GPU acceleration #118

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The idea is to use modern graphics cards to accelerate ADDA.

Marcus Huntemann and Georg Heygster have succeeded in porting ADDA to OpenCL, 
so incorporating their code should address this issue.

The current revision r1023 is capable of doing the matrix vector multiplication 
part on the GPU as long as no dimension is bigger than 512/256 on Nvidia/AMD 
GPUs respectively. This restriction is because of the used FFT routine.

This might be a new issue but belongs to GPU acceleration as well:
AMD GPUs seem to suffer a lot more from unaligned read and write operations on 
the global GPU memory in a kernel. So the next task is to align the global 
memory access using local memory as cache. Both, AMD and Nvidia GPUs will 
benefit from that.

I have added a few specific issues for further development of adda_ocl. It is 
already quite mature and almost ready for ADDA 1.1 release. Thus I am closing 
this issue.
