#include <omp.h> void main () { int i; double ZZ, func(), res=0.0; #pragma omp parallel for reduction(+:res) private(ZZ) for (i=0; i< 1000; i++){ ZZ = func(I); res = res + ZZ; } } In the last line: Actually added to a private ...

In our last two examples, numpy assumed that a[0,:] was the first vector, a[1,:] the second, and a[2,:] the third. Numpy.cross has an optional argument axisa that allows us to specify which axis defines the vectors. So, >>> a=np.array([[1,1,1],[0,1,0],[1,0,-1]]) >>> b=np.array([0...

You can pass parameters to the functions in tf.cond() using lambda and the code is as bellow. x = tf.placeholder(tf.float32) y = tf.placeholder(tf.float32) z = tf.placeholder(tf.float32) def fn1(a, b): return tf.mul(a, b) def fn2(a, b): return tf.add(a, b) pred = tf.placeholder(tf....

pthread_mutex_t queueMutex; pthread_cond_t queueCond; Queue queue; void Initialize() { //Initialize the mutex and the condition variable pthread_mutex_init(&queueMutex, NULL); pthread_cond_init(&queueCond, NULL); } void Producer() { //First we get some new data ...

The error message in the title is a common beginner mistake. Let's see how it arises and how to fix it. Suppose we need to compute the average value of a list of numbers; the following declaration would seem to do it, but it wouldn't compile: averageOfList ll = sum ll / length ll The problem is...

It's a good practice to scope patches using Refinements, but sometimes it's nice to load it globally (for example in development, or testing). Say for example you want to start a console, require your library, and then have the patched methods available in the global scope. You couldn't do this wit...

One major aspect of process substitution is that it lets us avoid usage of a sub-shell when piping commands from the shell. This can be demonstrated with a simple example below. I have the following files in my current folder: $ find . -maxdepth 1 -type f -print foo bar zoo foobar foozoo barzoo ...

A synchronous producer-consumer solution ensures that the consumer reads every data item written by the producer exactly one time. Asynchronous solutions allow the consumer to sample the output of the producer. Either the consumer consumes the data faster than it is produced, or the consumer consume...

This example uses the main procedure as the producer task. In Ada the main procedure always runs in a task separate from all other tasks in the program, see minimal example. ------------------------------------------------------------------ -- Sampling Consumer -- --------------------------------...

Some applications may want to create so-called "Fire & Forget" tasks which can be periodically triggered and do not need to return any type of value returned upon completion of the assigned task (for example, purging old temp files, rotating logs, autosaving state). In this example, w...

It is often necessary to execute a long-running task and use the result of that task once it has completed. In this example, we will create two classes: One which implements the Callable<T> interface (where T is the type we wish to return), and one which contains a main() method. AsyncValueT...

ArcPy is composed of a number of modules: arcpy — the basic functions and geoprocessing tools arcpy.mapping — access to mapping and map document tools arcpy.da — a data access module for working with feature classes and tables arcpy.sa — the Spatial Analyst extension module arcpy.na — the Net...

This example shows multiple producers and consumers sharing the same buffer. Protected entries in Ada implement a queue to handle waiting tasks. The default queuing policy is First In First Out. ------------------------------------------------------------------ -- Multiple producers and consumers ...

The traditional GLSL compilation model involves compiling code for a shader stage into a shader object, then linking multiple shader objects (covering all of the stages you want to use) into a single program object. Since 4.2, program objects can be created that have only one shader stage. This met...
