だ・か・らっ、Dia“l”yだってばさ!

これは『戯れ言』です。また、“Diary”ではなく“Dialy”です。つまり、日記に似て非なるものです。 所謂『日記』ではありません。お間違えの無いようお願いします。(^^;A

[Jul 08 08:52:15 UTC] RC5-72 benchmark summary :
                      Default core : #0 (CUDA 1-pipe 64-thd)
                      Fastest core : #9 (CUDA 1-pipe 64-thd busy wait)
[Jul 08 08:52:15 UTC] Core #9 is significantly faster than the default core.
                      The CUDA core selection has been made as a tradeoff between core speed
                      and responsiveness of the graphical desktop.
                      Please file a bug report along with the output of -cpuinfo
                      only if the the faster core selection does not degrade graphics performance.

微妙に改善された。
しかし、まだまだ遅い・・・ orz
