Description

opencl website  

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_OPENCL_DIR
  • HPC_OPENCL_INC
  • HPC_OPENCL_LIB

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
