Description
OpenCL™ (Open Computing Language) is a low-level API for heterogeneous computing that runs on GPUs. Using the OpenCL API, developers can launch compute kernels written using a limited subset of the C programming language on a GPU.
Required Modules
Serial
- opencl
System Variables
- HPC_{{#uppercase:opencl}}_DIR
- HPC_{{#uppercase:opencl}}_INC
Additional Information
The following example shows how to build a sample code with OpenCL.
[prescott@r11a-s17 ~]$ mkdir opencl [prescott@r11a-s17 ~]$ cd opencl [prescott@r11a-s17 opencl]$ module load opencl [prescott@r11a-s17 opencl]$ wget -q https://raw.github.com/smistad/OpenCL-Getting-Started/master/main.c [prescott@r11a-s17 opencl]$ wget -q https://raw.github.com/smistad/OpenCL-Getting-Started/master/vector_add_kernel.cl [prescott@r11a-s17 opencl]$ gcc -c -I$HPC_OPENCL_INC main.c -o main.o [prescott@r11a-s17 opencl]$ gcc main.o -o myopenclprog -l OpenCL
