9800GX2 可以10000以上阿~!
但是要單GPU破萬還要等等吧~:PPP:
按一下展開……

喔 ... 有點想生一塊來跑跑看 :PPP:
但為何看peter0968兄分享的9800GX2 ppd值不如預期 ? ;em28; 還是我看錯了 ...
 
在官網上讀到一篇討論關於使用 GPU 還是 CPU 算蛋白質摺疊哪種方式比較好?

What is better, Folding with GPU or with CPU?

由官方的發言

7im 說：
GPU is "less accurate" but many times faster, and more than makes up for it. But both types of clients are still important to the project, because not one type can do all of the work that Stanford needs done to make good progress.

GPU 模擬略微不準確, 但是處理速度快好幾十倍, 相對的可以彌補這方面的不足.

bruce 說：
The current generation of CPUs does, indeed contain the hardware that was once packaged separately as a math co-processor. It has evolved since then with the addition of SSE instruction sets and the uniprocessor client has been using SSE for quite a few years now and is able to process four floating point operations simultaneously with the speed varying since the early days of the PIII (at about 800 MHz) right up to the speeds of the most modern CPUs that we have today. In contrast, the GPUs typically process several hundred floating point operations simultaneously.

Nevertheless, the GPUs are limited in code complexity and, as has already been said, are not capable of running all of the types of calculations needed by FAH, but the ones they can run are extremely fast.
按一下展開……
GPU 運算能力仍被限制在譯碼上的開發, 並且無法完全適用來作於所有 FAH 的計算需求, 然而他們可算的部分卻又特別快.

想必這些訊息可以解除各位的疑惑. :)
 
FAH 界大事件

排名第一團隊 [H]ardOCP 今天被扣高達 1 千 2 百萬的積分

事因團隊有人暗藏 FAH 程式在 BT 分享軟件, 目前還未得知是哪套軟體 ....

肇事者 - party2go9820
 
他們的total point 好可怕;rr;
把程式暗藏在bt軟體，程式會自己執行嗎;rr;

monkp兄是在 f@h 的forum 看到這消息的嗎;tongue;

虧他寫得出來~用別人的電腦幫他跑分~....;em44;

看來我想潛入圖書館每台電腦的計畫還是就此打住好了


上禮拜去圖書館沒開是天意?:PPP:

Nightstalker 說：
在小弟心中只有4870x2才叫單卡:PPP:
按一下展開……

55ｍ　ＤＤＲ５　ＧＴＸ280比4870Ｘ２強一些些、那才叫單卡～～

不知ＰＰＤ值會如何？
