Functions
- assert (v, message)
-
Issues an error when the value of its argument `v` is false (i.e.,
nil or false); otherwise, returns all its arguments. `message` is an error
message; when absent, it defaults to "assertion failed!"
Parameters:
- v
- message
- collectgarbage (opt, arg)
-
This function is a generic interface to the garbage collector. It
performs different functions according to its first argument, `opt`:
* "stop": stops the garbage collector. * "restart": restarts the garbage collector. * "collect": performs a full garbage-collection cycle. * "count": returns the total memory in use by Lua (in Kbytes). * "step": performs a garbage-collection step. The step "size" is controlled by `arg` (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of * "arg". Returns true if the step finished a collection cycle. * "setpause": sets `arg` as the new value for the *pause* of the collector (see §2.10). Returns the previous value for *pause*. * "setstepmul": sets `arg` as the new value for the *step multiplier* of the collector (see §2.10). Returns the previous value for *step*.
Parameters:
- opt
- arg
- dofile (filename)
-
Opens the named file and executes its contents as a Lua chunk. When
called without arguments,
`dofile` executes the contents of the standard input (`stdin`). Returns
all values returned by the chunk. In case of errors, `dofile` propagates
the error to its caller (that is, `dofile` does not run in protected mode).
Parameters:
- filename
- error (message, level)
-
Terminates the last protected function called and returns `message`
as the error message. Function `error` never returns.
Usually, `error` adds some information about the error position at the
beginning of the message. The `level` argument specifies how to get the
error position. With level 1 (the default), the error position is where the
`error` function was called. Level 2 points the error to where the function
that called `error` was called; and so on. Passing a level 0 avoids the
addition of error position information to the message.
Parameters:
- message
- level
- getfenv (f)
-
Returns the current environment in use by the function.
`f` can be a Lua function or a number that specifies the function at that
stack level: Level 1 is the function calling `getfenv`. If the given
function is not a Lua function, or if `f` is 0, `getfenv` returns the
global environment. The default for `f` is 1.
Parameters:
- f
- getmetatable (object)
-
If `object` does not have a metatable, returns nil. Otherwise, if the
object's metatable has a `"__metatable"` field, returns the associated
value. Otherwise, returns the metatable of the given object.
Parameters:
- object
- ipairs (t)
-
Returns three values: an iterator function, the table `t`, and 0,
so that the construction
for i,v in ipairs(t) do *body* end
will iterate over the pairs (`1,t[1]`), (`2,t[2]`), ..., up to the
first integer key absent from the table.
Parameters:
- t
- load (func, chunkname)
-
Loads a chunk using function `func` to get its pieces. Each call to
`func` must return a string that concatenates with previous results. A
return of an empty string, nil, or no value signals the end of the chunk.
If there are no errors, returns the compiled chunk as a function; otherwise,
returns nil plus the error message. The environment of the returned function
is the global environment.
`chunkname` is used as the chunk name for error messages and debug
information. When absent, it defaults to "`=(load)`".
Parameters:
- func
- chunkname
- loadfile (filename)
-
Similar to `load`, but gets the chunk from file `filename` or from the
standard input, if no file name is given.
Parameters:
- filename
- loadstring (string, chunkname)
-
Similar to `load`, but gets the chunk from the given string.
To load and run a given string, use the idiom
assert(loadstring(s))()
When absent, `chunkname` defaults to the given string.
Parameters:
- string
- chunkname
- next (table, index)
-
Allows a program to traverse all fields of a table. Its first argument is
a table and its second argument is an index in this table. `next` returns
the next index of the table and its associated value.
When called with nil as its second argument, `next` returns an initial index and its associated value. When called with the last index, or with nil in an empty table, `next` returns nil.
If the second argument is absent, then it is interpreted as nil. In particular, you can use `next(t)` to check whether a table is empty. The order in which the indices are enumerated is not specified, *even for numeric indices*. (To traverse a table in numeric order, use a numerical for or the `ipairs` function.)
The behavior of `next` is *undefined* if, during the traversal, you assign any value to a non-existent field in the table. You may however modify existing fields. In particular, you may clear existing fields.
Parameters:
- table
- index
- pairs (t)
-
Returns three values: the `next` function, the table `t`, and nil,
so that the construction
for k,v in pairs(t) do *body* end
will iterate over all key–value pairs of table `t`.
See function `next` for the caveats of modifying the table during its
traversal.
Parameters:
- t
- pcall (f, arg1, ...)
-
Calls function `f` with the given arguments in *protected mode*. This
means that any error inside `f` is not propagated; instead, `pcall` catches
the error and returns a status code. Its first result is the status code (a
boolean), which is true if the call succeeds without errors. In such case,
`pcall` also returns all results from the call, after this first result. In
case of any error, `pcall` returns false plus the error message.
Parameters:
- f
- arg1
- ...
- print (...)
-
Receives any number of arguments, and prints their values to `stdout`,
using the `tostring` function to convert them to strings. `print` is not
intended for formatted output, but only as a quick way to show a value,
typically for debugging. For formatted output, use `string.format`.
Parameters:
- ...
- rawequal (v1, v2)
-
Checks whether `v1` is equal to `v2`, without invoking any
metamethod. Returns a boolean.
Parameters:
- v1
- v2
- rawget (table, index)
-
Gets the real value of `table[index]`, without invoking any
metamethod. `table` must be a table; `index` may be any value.
Parameters:
- table
- index
- rawset (table, index, value)
-
Sets the real value of `table[index]` to `value`, without invoking any
metamethod. `table` must be a table, `index` any value different from nil,
and `value` any Lua value.
This function returns `table`.
Parameters:
- table
- index
- value
- select (index, ...)
-
If `index` is a number, returns all arguments after argument number
`index`. Otherwise, `index` must be the string `"#"`, and `select` returns
the total number of extra arguments it received.
Parameters:
- index
- ...
- setfenv (f, table)
-
Sets the environment to be used by the given function. `f` can be a Lua
function or a number that specifies the function at that stack level: Level
1 is the function calling `setfenv`. `setfenv` returns the given function.
As a special case, when `f` is 0 `setfenv` changes the environment of the
running thread. In this case, `setfenv` returns no values.
Parameters:
- f
- table
- setmetatable (table, metatable)
-
Sets the metatable for the given table. (You cannot change the metatable
of other types from Lua, only from C.) If `metatable` is nil, removes the
metatable of the given table. If the original metatable has a `"__metatable"`
field, raises an error.
This function returns `table`.
Parameters:
- table
- metatable
- tonumber (e, base)
-
Tries to convert its argument to a number. If the argument is already
a number or a string convertible to a number, then `tonumber` returns this
number; otherwise, it returns nil.
An optional argument specifies the base to interpret the numeral. The base
may be any integer between 2 and 36, inclusive. In bases above 10, the
letter '`A`' (in either upper or lower case) represents 10, '`B`' represents
11, and so forth, with '`Z`' representing 35. In base 10 (the default),
the number can have a decimal part, as well as an optional exponent part
(see §2.1). In other bases, only unsigned integers are accepted.
Parameters:
- e
- base
- tostring (e)
-
Receives an argument of any type and converts it to a string in a
reasonable format. For complete control of how numbers are converted, use
`string.format`.
If the metatable of `e` has a `"__tostring"` field, then `tostring` calls
the corresponding value with `e` as argument, and uses the result of the
call as its result.
Parameters:
- e
- type (v)
-
Returns the type of its only argument, coded as a string. The possible
results of this function are "
`nil`" (a string, not the value nil), "`number`", "`string`", "`boolean`",
"`table`", "`function`", "`thread`", and "`userdata`".
Parameters:
- v
- unpack (list, i, j)
-
Returns the elements from the given table. This function is equivalent to
return list[i], list[i+1], ..., list[j]
except that the above code can be written only for a fixed number of
elements. By default, `i` is 1 and `j` is the length of the list, as
defined by the length operator (see §2.5.5).
Parameters:
- list
- i
- j
- xpcall (f, err)
-
This function is similar to `pcall`, except that you can set a new
error handler.
`xpcall` calls function `f` in protected mode, using `err` as the error
handler. Any error inside `f` is not propagated; instead, `xpcall` catches
the error, calls the `err` function with the original error object, and
returns a status code. Its first result is the status code (a boolean),
which is true if the call succeeds without errors. In this case, `xpcall`
also returns all results from the call, after this first result. In case
of any error, `xpcall` returns false plus the result from `err`.
Parameters:
- f
- err
- module (name, ...)
-
Creates a module. If there is a table in `package.loaded[name]`,
this table is the module. Otherwise, if there is a global table `t`
with the given name, this table is the module. Otherwise creates a new
table `t` and sets it as the value of the global `name` and the value of
`package.loaded[name]`. This function also initializes `t._NAME` with the
given name, `t._M` with the module (`t` itself), and `t._PACKAGE` with the
package name (the full module name minus last component; see below). Finally,
`module` sets `t` as the new environment of the current function and the
new value of `package.loaded[name]`, so that `require` returns `t`.
If `name` is a compound name (that is, one with components separated by
dots), `module` creates (or reuses, if they already exist) tables for each
component. For instance, if `name` is `a.b.c`, then `module` stores the
module table in field `c` of field `b` of global `a`.
This function can receive optional *options* after the module name, where
each option is a function to be applied over the module.
Parameters:
- name
- ...
- require (modname)
-
Loads the given module. The function starts by looking into the
`package.loaded` table to determine whether `modname` is already
loaded. If it is, then `require` returns the value stored at
`package.loaded[modname]`. Otherwise, it tries to find a *loader* for
the module.
To find a loader, `require` is guided by the `package.loaders` array. By
changing this array, we can change how `require` looks for a module. The
following explanation is based on the default configuration for
`package.loaders`.
First `require` queries `package.preload[modname]`. If it has a value,
this value (which should be a function) is the loader. Otherwise `require`
searches for a Lua loader using the path stored in `package.path`. If
that also fails, it searches for a C loader using the path stored in
`package.cpath`. If that also fails, it tries an *all-in-one* loader (see
`package.loaders`).
Once a loader is found, `require` calls the loader with a single argument,
`modname`. If the loader returns any value, `require` assigns the returned
value to `package.loaded[modname]`. If the loader returns no value and
has not assigned any value to `package.loaded[modname]`, then `require`
assigns true to this entry. In any case, `require` returns the final value
of `package.loaded[modname]`.
If there is any error loading or running the module, or if it cannot find
any loader for the module, then `require` signals an error.
Parameters:
- modname

"Kublai Khan does not necessarily believe everything Marco Polo says when he describes the cities visited on his expeditions, but the emperor of the Tartars does continue listening to the young Venetian with greater attention and curiosity than he shows any other messenger or explorer of his."
So begins Italo Calvino's compilation of fragmentary urban images. As Marco tells the khan about Armilla, which "has nothing that makes it seem a city, except the water pipes that rise vertically where the houses should be and spread out horizontally where the floors should be," the spider-web city of Octavia, and other marvelous burgs, it may be that he is creating them all out of his imagination, or perhaps he is recreating details of his native Venice over and over again, or perhaps he is simply recounting some of the myriad possible forms a city might take.

Phoenix Point trailer sets the grim scene ahead of next week's launch
by Fraser BrownX-COM spiritual successor Phoenix Point is only a week away from launch, and things aren't looking too hot for Earth, judging by the new trailer. Give it a watch above to see what you're getting yourself in for if you join Project Phoenix.
The crowdfunded tactics game was originally due out last year, but it was postponed to give the team more time to match the expectations people had after the successful Fig campaign. Designer and X-COM creator Julian Gollop said it had grown larger than initially planned.
With the release date in sight, the team is working on balance, polish and fixing bugs. Based on feedback from testers, it's reworked faction weapon stats, reduced the frequency of Haven attacks and made missile launchers less accurate. There have been a few other changes, which you can read in the November development update.
Phoenix Point is due out on December 3 at 7 pm GMT/11 am PST. While it's an Epic Games Store exclusive, at least for a year, Xbox Game Pass subscribers will also get access. It should launch on the platform at the same time as the Epic Games Store version, though the timing depends on Microsoft.

F.A.Q.#
Q: Pytorch supports quantization-aware training. Why should I use Brevitas?
A: Quantization in Pytorch is designed to target specific backends supported by PyTorch itself (currently FBGEMM and qnnpack).
Brevitas is designed as a platform to implement novel quantization algorithms to target a variety of hardware backends adhering to a loose set of assumptions (i.e. uniform affine quantization).
Q: How can I train X/Y and run it on hardware W/Z? I can’t find any documentation.
A: Brevitas is still sparsely documented. Until the situation improves, feel free to open an issue or ask on our gitter channel.
Q: Training with Brevitas is slow and/or I can’t fit the same batch size as with floating-point training. Why? What can I do?
A: Quantization-aware training involves a lot of element-wise operations, which carry low arithmetic intensity and contribute to a more involved computational graph during backpropragation. As such, it typically ends up being slower and more resource-intensive than standard floating-point training.
Brevitas in particular is biased towards greater flexibility, at the cost of some training-time effieciency. The general principle is that it’s trading off more complexity at training time for more efficiency at inference time.
To mitigate somewhat the slow-down, try enabling BREVITAS_JIT as reported in the Settings section.
Q: Inference with Brevitas is slow. I thought the point of quantization was to make my model faster at inference time. What I am doing wrong?
A: Brevitas is concerned with modelling a reduced precision data-path, it does not provide inference-time acceleration on its own. To achieve acceleration, you should export your Brevitas model to a downstream toolchain / backend. See the
Q: My (C/G/T)PU supports float16 / bfloat16 / bfloat19 training. Can I use it to train with Brevitas?
A: Datatypes outside of float32 at training time have not been tested. That includes training on TPU / Pytorch-XLA. Do the math in terms of which reduced-precision integers can reasonably fit in a reduced-precision floating-point format at training time, and use at your own risk.

Plane class
Basic usage
Plane class inherits from the BasePlane class, which is a class that just sets up the WebGL (buffers and attributes) and sources loading parts of a plane.
Plane extends the BasePlane class by adding various properties and methods to keep your WebGL plane in sync with its associated HTML element. All sizes and positions are handled by two matrices that you will have to use inside your vertex shader: the model view matrix and the projection matrix.
Creation
To create a plane, you will need to pass a mandatory HTML element. It will be used to calculate the size and position of your plane.
You will have to use the addPlane method of your Curtains class object:
Parameters
The code above will create a basic plane but you won't be able to do much with it. The addPlane method has a second parameter in which you can pass all the options you need:
See the list of all the addPlane possible parameters to know more.
Passing shaders via data attributes
You can also pass the IDs of the vertex and fragment shaders using respectively data-vs-id and data-fs-id attributes of your plane HTML element:
Properties
-
alwaysDraw (boolean): v2.0
Whether the WebGL renderer should always draw the plane or if it should draw it only when the plane is contained in the canvas viewport. Used for performance optimizations.
Check the Plane properties and transformations cheat sheet example to see how it could be used.
-
autoloadSources (boolean): v2.0read only
Whether the sources (images, videos and canvases HTML children elements of your plane) should be loaded and according textures created on plane initialization.
-
canvases (array): v1.4
An array containing all the canvases loaded via the load methods into the plane.
-
crossOrigin (string): v1.4
The cross origin process used to load the medias.
-
cullFace (string): v6.0
Which face of the plane should be culled (ie not drawn). Could either be "back" (only the front side of the plane is drawn), "front" (only the back side of the plane is drawn) or "none" (all the side of the plane are drawn). Default to "back".
You might want to change the default culling behavior if you apply a rotation along the X or Y axis for example (therefore showing the back side of the plane).Check the Plane properties and transformations cheat sheet example to see how it could be used.
-
drawCheckMargins (object): v4.0
Additional margins to add in the draw check calculations, in pixels.
Positive value means the plane will be drawn even if outside the canvas by less than the value, negative value means the plane will be hidden if inside the canvas by more than the value.
Useful if you're messing with the vertices positions in your vertex shader.- top float margin to apply when comparing the top side of the plane and the bottom side of the canvas (0 by default).
- right float margin to apply when comparing the right side of the plane and the left side of the canvas (0 by default).
- bottom float margin to apply when comparing the bottom side of the plane and the top side of the canvas (0 by default).

Examples: used in Plane properties and transformations cheat sheet and Post processing scrolling wheel with custom transform origin example.
-
updatePosition(): v1.6 triggers reflow
Internally, the planes positions are updated only when the window is resized. But if you are updating your plane HTML element position without resizing the window (typically while scrolling, animating its CSS position or transform values), call this method in your animation loop at the same time.
This method calls getBoundingClientRect() therefore causing a reflow/layout repaint of the page. See setRelativePosition to update your plane position without any reflow. -
updateScrollPosition(): v4.0
Use it if you want to handle the scroll event by yourself, like with a virtual scroll library. You will have to pass the scroll values to the Curtains class with updateScrollValues() before calling this method.

This page demonstrates techniques for improving the accessibility of data visualizations. It is for demonstration purposes only. See full DOHMH COVID-19 Data webpages.
Properly formatted tables, with labeled headers and rows, offer better access to users with screen readers than charts or graphs do.
Visualizations can help sighted users make sense of the data, but charts are usually inaccessible to users with screen readers. The screen reader does not have enough information to interpret the values it encounters. It reads off a series of values without making clear what these values are.
This table shows the same data as the chart above (actually, it also shows additional data in the source file). The table reads the same source file as the chart. It is formatted to offer better access to a person using a screen reader.
It's limited by unlabelled buttons, but allows somebody using a screen reader to access the data.
We can combine these experiences by using the aria-hidden="true"
attribute on visual-only elements. This attribute makes that element invisible to a screenreader.
For content intended for screen readers, we use a CSS class
.sronly {position: absolute; left: -9999px;}
. The screen reader encounters it as it reads
through the code, but it's
positioned off the screen, not visible to sighted users.
By combining these techniques, we create a page of visualizations that offers more accessible data products to different types of users.
This map is best for a sighted audience. The table is another helpful way to explore the data. Clearly labelling it as an accessible table, offers better access to users with visual impairments.

Both of the currently supported methods for LINGO computations with pySIML share the same general data flow and methods, to make it easy to switch between CPUs and GPUs as needed. The overall structure of a Tanimoto computation with pySIML is as follows:
- Read SMILES (from file, database, generator, etc)
- Preprocess SMILES for reference and query sets (see section Preprocessing SMILES in pySIML) into a pair of ‘SMILES sets’, each consisting of a Lingo matrix, count matrix, length vector, and magnitude vector.
- Create a LINGO comparator object (a CPULingo, GPULingo, or OCLLingo object)
- Initialize the comparator with the reference and query SMILES sets using the set_refsmiles and set_qsmiles functions.
- Request a single row from the Tanimoto matrix using the getTanimotoRow or getTanimotoRow_async methods, or a contiguous range of rows using getMultipleRows or getMultipleRows_async.
The following is a simple demonstration of how to calculate a full N x N similarity matrix on a set of compounds read in from a file. Note that it lacks niceties such as error-checking; a more detailed example code is present in the examples directory:
import sys
import numpy
from pysiml.compiler import cSMILEStoMatrices
from pysiml.CPULingo import CPULingo
f = open(sys.argv[1],"r")
smiles = f.readlines()
f.close()
numMols = len(smiles)
# We use cSMILEStoMatrices because it is almost 100x as fast as
# SMILEStoMatrices, and more correct to boot.
#
# The SMILES compiler also returns the molecule name associated
# with each row of the output matrices
(lingos,counts,lengths,mags,names) = cSMILEStoMatrices(smiles)
# Construct a similarity object. This could also be a GPULingo
comparator = CPULingo()
# Initialize the comparator with our SMILES sets. Since this
# computation is a self-similarity matrix, the reference and
# query sets are the same
comparator.set_refsmiles(lingos,counts,lengths,mags)
comparator.set_qsmiles(lingos,counts,lengths,mags)
# Create an empty storage place to put the result
similarityMatrix = numpy.empty((numMols,numMols))
# CPULingo-specific: see if we can run the computation in parallel
numProcs = 1
if comparator.supportsParallel():
# If we can do a row-parallel computation (OpenMP supported), choose the
# number of processors here
numProcs = 4
similarityMatrix[:,:] = comparator.getMultipleRows(0,numMols,nprocs=numProcs)
print similarityMatrix
The following sections explain details of the CPULingo and GPULingo APIs and differences in their respective behavior.
This module exposes the API for computing LINGO similarities on a CPU. Calculations of multiple rows can be parallelized across multiple CPUs, if the library has been built with OpenMP support. There is currently no support for parallelizing the computation of a single row across multiple CPUs.
The CPULingo object is the interface to compute LINGOs on a CPU. Creating multiple CPULingo objects will not parallelize computations on each across multiple CPUs (as with GPULingo); the only parallelism currently exposed is across rows, using OpenMP.
For interface consistency, CPULingo exposes asynchronous operation methods (getTanimotoRow_async() and getMultipleRows_async()); however, these methods as currently implemented are not actually asynchronous operations.
Object to handle computation of LINGO similarities on the CPU
Return True if all asynchronous operations on this object have completed.
In current implementation, always returns True.
Computes multiple Tanimoto rows rowbase:rowlimit corresponding to comparing every SMILES string in the query set with the reference SMILES strings having index row, row+1, ..., rowlimit-1 in the reference set, and returns this block of rows.
If pySIML has been built with OpenMP enabled, nprocs may be set higher than 1 to parallelize computations over multiple CPUs (each CPU will handle a disjoint set of rows). If called with nprocs larger than 1 on a non-OpenMP build of pySIML, print a warning to stderr and compute with one CPU.
Computes multiple Tanimoto rows rowbase:rowlimit corresponding to comparing every SMILES string in the query set with the reference SMILES strings having index row, row+1, ..., rowlimit-1 in the reference set, and stores this block of rows internally as the last asynchronous result value.
If pySIML has been built with OpenMP enabled, nprocs may be set higher than 1 to parallelize computations over multiple CPUs (each CPU will handle a disjoint set of rows). If called with nprocs larger than 1 on a non-OpenMP build of pySIML, print a warning to stderr and compute with one CPU.
To retrieve the result block, call retrieveAsyncResult().
Note that this function is actually synchronous, due to the limitations of running on the CPU; it will not return until the block has been completely calculated.
Computes the single Tanimoto row row corresponding to comparing every SMILES string in the query set with the single reference SMILES string having index row in the reference set, and stores this row internally as the last asynchronous result value.
To retrieve the result row, call retrieveAsyncResult().
Note that this function is actually synchronous, due to the limitations of running on the CPU; it will not return until the row has been completely calculated.
Returns result from last asynchronous computation (getTanimotoRow_async() or getMultipleRows_async()).
Note that this result is only guaranteed to be valid if no operations have been run on this CPULingo object since the asynchronous call, except for asyncOperationsDone() and retrieveAsyncResult().
If no asynchronous operations have been invoked on this object, result is undefined.
Return True if this installation of pySIML was built with OpenMP support for parallel calculations.
Note that even if this function returns False, the getMultipleRows() and getMultipleRows_async() methods can still be called with nprocs > 1, but only one processor will actually be used
This module exposes the API for computing LINGO similarities on a CUDA-capable GPU. It uses the pycuda library to interface with the GPU; in particular, due to bugs related to context management in pycuda 0.93 and before, pycuda 0.94 or greater is required.
The GPULingo object is the interface to compute LINGOs on a single GPU. To do similarity calculations on multiple GPUs, create multiple GPULingo objects, passing a different CUDA device ID to each one’s constructor:
gpu0 = pysiml.GPULingo(0)
gpu1 = pysiml.GPULingo(1)
By using the asynchronous operations on each object (getTanimotoRow_async() and getMultipleRows_async()), similarity calculations can be carried out simultaneously on multiple GPUs using only one host thread:
# gpu0 and gpu1 have been initialized with reference and query SMILES sets
# Carry out simultaneous computation of rows 0 to 10 of each set on both GPUs
gpu0.getMultipleRows_async(0,10)
gpu1.getMultipleRows_async(0,10)
# The busy waits could be replaced by a sleep, or any other work
while not gpu0.asyncOperationsDone():
pass
gpu0result = gpu0.retrieveAsyncResult()
while not gpu1.asyncOperationsDone():
pass
gpu1result = gpu1.retrieveAsyncResult()
After an asynchronous computation has been requested on a GPULingo object, check asyncOperationsDone() to see when the job is complete. Once the job is done, retrieveAsyncResult() can be called to retrieve the result. Note that the retrieved result is guaranteed to be valid only if no methods were called on the GPULingo object after the asynchronous request, except for asyncOperationsDone() and retrieveAsyncResult().

Result is a tuple of (matrix,vector). The vector contains, for each reference string in rowbase:rowlimit, the number of neighbors found. The matrix is of size (rowlimit-rowbase, maxNeighborsFound), where maxNeighborsFound is the maximum value in the returned vector. Each row of the matrix (corresponding to one reference SMILES string) has as its elements the query indices of neighbors. In row i, only the first vector[i] elements are valid (that is, the values elements of the matrix beyond the number of neighbors found for a given row are undefined).

Note that this result is only guaranteed to be valid if no operations have been run on this object since the asynchronous call, except for asyncOperationsDone() and retrieveAsyncResult().
If no asynchronous operations have been invoked on this object, result is undefined. If an asynchronous operation is still pending, this method will block until completion.
Sets the reference SMILES set to use Lingo matrix qsmilesmat, count matrix qcountsmat, and length vector querylengths. If querymags is provided, it will be used as the magnitude vector; else, the magnitude vector will be computed (on the GPU) from the count matrix.
Because of hardware limitations, the query matrices (qsmilesmat and qcountsmat) must have no more than 65,536 rows (molecules) and 32,768 columns (Lingos). Larger computations must be performed in tiles.

This module exposes the API for computing LINGO similarities on an OpenCL-capable GPU, CPU, or other accelerator device. It uses the pyopencl library to interface with OpenCL.
The OCLLingo object is the interface to compute LINGOs on a single OpenCL device. Multiple OCLLingo objects can be used (on the same device or multiple devices); in particular, similarity calculations may be parallelized across multiple GPUs by creating multiple OCLLingo objects, one per device. To build an OCLLingo object, an OpenCL device (obtained from an OpenCL Platform using pyopencl) must be passed to the constructor:
import pyopencl as cl
platform = cl.get_platforms()[0] # Use first platform
dev0 = platform.get_devices()[0]
dev1 = platform.get_devices()[1]
gpu0 = pysiml.OCLLingo(dev0)
gpu1 = pysiml.OCLLingo(dev1)
By using the asynchronous operations on each object (getTanimotoRow_async() and getMultipleRows_async()), similarity calculations can be carried out simultaneously on multiple GPUs using only one host thread:
# gpu0 and gpu1 have been initialized with reference and query SMILES sets
# Carry out simultaneous computation of rows 0 to 10 of each set on both GPUs
gpu0.getMultipleRows_async(0,10)
gpu1.getMultipleRows_async(0,10)
# The busy waits could be replaced by a sleep, or any other work
while not gpu0.asyncOperationsDone():
pass
gpu0result = gpu0.retrieveAsyncResult()
while not gpu1.asyncOperationsDone():
pass
gpu1result = gpu1.retrieveAsyncResult()
After an asynchronous computation has been requested on a OCLLingo object, check asyncOperationsDone() to see when the job is complete. Once the job is done, retrieveAsyncResult() can be called to retrieve the result. Note that the retrieved result is guaranteed to be valid only if no methods were called on the OCLLingo object after the asynchronous request, except for asyncOperationsDone() and retrieveAsyncResult().

In consideration of the day and hour of my birth, it was declared by the nurse, and by some sage women in the neighbourhood who had taken a lively interest in me several months before there was any possibility of our becoming personally acquainted, first, that I was destined to be unlucky in life; and secondly, that I was privileged to see ghosts and spirits; both these gifts inevitably attaching, as they believed, to all unlucky infants of either gender, born towards the small hours on a Friday night.
Demonstration Area
Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else,
these pages must show. To begin my life with the beginning of my life, I record that I was born
(as I have been informed and believe) on a Friday, at twelve o’clock at night. It was remarked that
the clock began to strike, and I began to cry, simultaneously.

ic-always-update
- The Always Update AttributeThe ic-always-update
attribute forces an element to always update the DOM when new content
is downloaded, even if the current content is identical to the downloaded content.
This can be useful if you want to clean non-DOM related state (such as checkboxes) after an operation causes an update.
The value of this attribute can be either true
or false
No effect.


What is xargs?
xargs
is a UNIX command line utility for bulding an execution pipeline from stdin
(standard input). xargs
can be used with any command that need the stdin
as argument such as echo
, mkdir
, rm
to cite the simplest command
Illustration
The default behavior of xargs
is to take items from the stdin
and execute a command once for every argument.
In this following example xargs
takes the output of the command echo
and pipes the output as arguments for the command mkdir
. In the example below, we end up with 3 new directories one, two and three.
echo "one, two, three" | xargs mkdir
ls
one two tree
xargs' common used options
-p, ---interactive
Prompt the user about whether to run each command line and read a line from the terminal. Only run the command line if the response starts with y' or
Y'. Implies -t.
-r, --no-run-if-empty
If the standard input does not contain any nonblanks, do not run the command. Normally, the command is run once even if there is no input. This option is a GNU extension.
-o, --open-tty
Reopen stdin as /dev/tty in the child process before executing the command. This is useful if you want xargs to run an interactive application.
--delimiter=delim, -d delim
Input items are terminated by the specified character. The specified delimiter may be a single character, a C-style character escape such as \n, or an octal or hexadecimal escape code.

| global sort {pbdMPI} | R Documentation |
This function globally sorts distributed data for all ranks.
comm.sort(x, decreasing = FALSE, na.last = NA, comm = .pbd_env$SPMD.CT$comm, status = .pbd_env$SPMD.CT$status)
x |
a vector. |
decreasing |
logical. Should the sort order be increasing or decreasing? |
na.last |
for controlling the treatment of |
comm |
a communicator number. |
status |
a status number. |
The distributed quick sort is implemented for this functions.
The returns are the same size of x
but in global sorting order.
All ranks may not have a NULL x
.
