Check and finalize the warp specific features for the OpenCL kernel #39

Closed ancahamuraru closed 9 years ago

ancahamuraru commented 9 years ago

Currently the warp size is dynamically computed and sent to the kernel through the WARP_SIZE_TEST macro.

Test WARP_SIZE_TEST usage inside the kernel.

Check if WARP_SIZE_TEST and WARP_SIZE can be merged into one single parameter.

Implement any other warp specific feature not yet implemented. For example this line still uses WARP_SIZE: reduce_energy_pow2(f_buf + (tidx & WARP_SIZE), e_lj, e_el, tidx & ~WARP_SIZE);

Check also #38

WARP_SIZE_TEST not used anymore inside the kernel. The kernel still uses WARP_SIZE as defined for NVIDIA. It works for AMD as the wavefront size is 64.
