For C# there exist many wrappers that offer an interface to communicate with OpenCL. OpenCL.NET: This is one of the most low level wrappers out there. It offers a complete implementation of the OpenCL API for C# without adding any abstraction at all. So C\C++ examples are easily ported for this ...

if I forget the password then I'll get error. $ mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) I tried to solve the issue by first knowing the status: $ systemctl status mysql.service mysql.service - MySQL Community ...

In order to show an alert dialog containing a link which can be opened by clicking it, you can use the following code: AlertDialog.Builder builder1 = new AlertDialog.Builder(youractivity.this); builder1.setMessage(Html.fromHtml("your message,<a href=\"http://www.google.com\"&gt...

<?php $con = mysqli_connect("localhost", "root", "", "database"); ?>

Atom is versatile and flexible text editor and has hundreds of community-made, open-source packages that can compile and run source files, for many languages. This guide will show how easy it is to code Python with the Atom editor. This guide assumes you do not have Python nor Atom installed in you...

$data = $result->mysqli_fetch_array(MYSQLI_NUM);

$data = $result->mysqli_fetch_array(MYSQLI_BOTH);

The key of parallelism is to use multiple threads to solve a problem (duh.) but there are some differences to classical multithreaded programming in how threads are organized. First lets talk about your typical GPU, for simplicities sake I'll focus on A GPU has many processing cores, which make it...

The GPU offers six different memory regions. They differ in their latency, size and accessibility from different threads. Global Memory: The largest memory available and one of the few ones to exchange data with the host. This memory has the highest latency and is available for all threads. Cons...

The typical scenario for your memory usage is to store the source data and the processed data in the global memory. When a threadblock starts, it first copies all relevant parts into the shared memory before getting their parts into the registers. Memory access latency also depends on your memory s...

OpenCL Kernels can be either executed on the GPU or the CPU. This allows for fallback solutions, where the customer may have a very outdated system. The programmer can also choose to limit their functionality to either the CPU or GPU. To get started using OpenCL, you'll need a 'Context' and a 'Devi...

Kernels can be compiled at runtime on the target device. To do so, you need the kernel source code the target device on which to compile a context built with the target device A quick terminology update: A program contains a collection of kernels. You can think of a program as a complete C/C...

To initiate any operation on your devices, you'll need a command queue for each device. The Queue keeps track of different calls you did to the target device and keeps them in order. Most commands can also be executed either in blocking or non-blocking mode. Creating a queue is pretty straightforwa...

So now we come down to the real stuff, executing your kernels on the parallel device. Please read about the hardware basics to fully understand the kernel dispatching. First you'll need to set the kernel arguments before actually calling the kernel. This is done via err = Cl.SetKernelArg(_kernel, ...

scons describes running phases itself. Running it over an empty SConstruct yields this: $ scons scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... scons: `.' is up to date. scons: done building targets. To suppress phase messages, add -Q op...
