hi all,
My GPU conf is:-
Name : GeForce 9800 GX2
I am confused about the threads per block i can use.
Is that Thr/Blk per dimension? ie. can u get 512512 64 threads for my 3D block of size 512512 64 ??
what are the other factors thread per block is dependent upon?
thank you

The maximum number of threads per block is 512, total. The maximum in each dimension is 512, 512, 64…so you could have a 512x1x1 block, a 256x2x1, 3x2x64, etc., as long as the total number is less than 512.
