1. Re: Could this be the reason "only" about 100 CUDA cores are utilized?
ECBowen Jan 3, 2011 4:11 PM (in response to gtacyclist)This 100 Cuda Core myth is so out of control. There is not a limitation to the amount of CUDA cores the MPE uses or any other CUDA based application. CUDA does not work that way. Think of it like a sprinkler. You have 1 stream of water coming in and a water droplets going to the first available opening. Cuda throws out threads to any Core available. It is not like standard CPU based applications where it has to be multithreaded correctly to thread out to multiple cores. Some benchmark site did a test and came to an incorrect assumption because they did not understand how CUDA really works. There use to be a very extensive white paper on Nvidia's website that explained CUDA memory management and threading. Last time I looked for it , it was no longer there but it may be back up again. Sheesh this has become as bad as someone putting something up on Wikapedia.
