v2.9105.512 (beta8) on 9500GT

dnetc CUDA

早速、9500GTでbeta8を試してみた。
CUDAを2.1から2.2にあげる。
ちゃんとCUDA Clientを停止して、bench!

$ ./dnetc -shutdown

[Jul 27 01:03:25 UTC] RC5-72 benchmark summary :
                      Default core : #0 (CUDA 1-pipe 64-thd)
                      Fastest core : #6 (CUDA 4-pipe 64-thd)
[Jul 27 01:03:25 UTC] Core #6 is marginally faster than the default core.
                      Testing variability might lead to pick one or the other.


ここで確認したときは、
core #1 (CUDA 2-pipe 64-thd)を使って、
77,781,297 keys/sec
でしたので、やはり速度は1/2ですかねぇ。
芳しく御座いませんねぇ。
面倒なので、このまま放置。
9800GTX+は、beta7のままってことで。
