opencl-examples

This repository contains examples of running OpenCL kernels from C/C++. It requires OpenCL to be installed on a machine. To ensure that OpenCL is installed run the following command which will list all the available OpenCL devices in the system:

$ clinfo

The examples in this repository have split the application code to two parts:

• host.cpp: The host code contains the functionality for the initialization of the OpenCL data structures and the input data as well as the orchestration of the execution on platform <platform_id>.
• mykernel.cl: The kernel code is the parallel code that can run on a heterogeneous hardware accelerator (e.g. multicore CPU, GPU).

To run the examples, open a terminal and execute:

For Saxpy:

$ cd saxpy
$ make
$ # ./host <platform_id> <elements>
$ ./host 1 1024

For Matrix Multiplication:

To run the MatrixMultiplication example, open a terminal and execute:

$ cd mxm
$ make
$ # ./host <platform_id> <elements>
$ ./host 1 1024
