Dynamic code path selection according to processor #23

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

Currently the NVTT library has to be compiled for a specific instruction
set. The SSE2 code path is 40% faster than the SSE code path, and no SSE is
much slower, 3-4 times slower. It would be nice to automatically select the
best code path dynamically according to the available CPU capabilities.
