Hi All, ATI STREAM SDK 2.4 is compatiable with my Ati hd 6850. I ran the test burst with the GPU. I have following queries if you can answer please: 1- The test burst (i.e. a single burst) is taking more time on GPU i.e. 2 minutes as compared to CPU 1.5 minutes. Why is that? I am using two hard

Hi, What are the current performance of the lookup code running on the GPU ? (even in not yet released version). In rounds per second ? (one round being going from 64 bits states - 100 + 64 bits generated) Cheers, Sylvain ___ A51 mailing list
