However, if GPU support is not available, Aparapi will revert to Java threads.

The API will convert Java byte codes to OpenCL at runtime. This makes the API largely independent from the graphics card used. The API was initially developed by AMD but has been released as open source. This is reflected in the basic package name, com.amd.aparari.
