CUDA Cores not showing up correctly
Posted: Mon Feb 21, 2011 9:56 pmI have a Quadro 4000, and CUDA-Multiforcer and table gen apps are only reporting 64 CUDA cores. The Quadro 4000 has 256 actual CUDA cores.
Any ideas?
Any ideas?
What version? 0.72, or 0.80 alpha?
If it's 0.72, that's a known issue - nVidia changed their way of counting shader processors when they went to sm_20, and the 0.72 code only knows the old way. The 0.80 code should be correct.
In either case, it's only a reporting issue - all the cores are being used properly.
