Generating OpenCL C kernels from OpenACC
Tristan Vanderbruggen, John Cavazos · 2014
Hardware accelerators are now a common way to improve the performances of compute nodes. This performance improvement has a cost: applications need to be rewritten to take advantage of the new hardware. OpenACC is a set of compiler directives to target hardware accelerators with minimal modification of the original application. In this paper, we present the generation of OpenCL C kernels from OpenACC annotated codes. We introduce a method to produce multiple kernels for each OpenACC compute region.
