Hi Dave, Yes... 8300 is old and not even listed as a supported CUDA platform, but it supports CUDA, in fact.
It is Multiprocessors x Core/MP = Cores : 1 (MP) x 8 (Cores/MP) = 8 (Cores) Well... if you need a guinea pig ... let me know and I run your tests in my old GPU. I plan to install 2 x 8800 GTX cards in my topology. Not sure if they will fit, etc, etc... but it will become an interesting environment to play. My wife has laptop with a 8600 GS (running Kubuntu) which eventually will participate... if got her permission :D Cheers :) Richard Gomes M: +44(77)9955-6813 http://tinyurl.com/frgomes twitter: frgomes JQuantLib is a library for Quantitative Finance written in Java. http://www.jquantlib.org/ twitter: jquantlib On 19/11/10 01:21, Dave Cunningham wrote: > In the case of my old GeForge 8300 board, they report: > >> >> autoThreads = 1 >> autoBlocks = 8 >> >> > I've never heard of an 8300, I assume it has 2/16 of the MPs enabled? > > They should never return that, they should return threads as a multiple of > 64 and blocks as a multiple of 2.
