Overview
The HMPP (Hybrid Multicore Parallel Programming) open standard directives are an OpenMP-like approach for explicitly offloading portions of code to the GPU and scaling host code. This approach leverages the strength of the GPU as a hardware accelerator (HWAs) to replace traditional SIMD computing units. PathScale ENZO and CAPS HMPP Workbench compiler are radically different implementations, but both allow the programmer to write hardware independent applications that can significantly speed up C and Fortran code.
Highlights
- Easy directive based approach
- Open standard
- Supports both host and accelerator targets
- Production ready now
- Multiple vendor implementations
