[PS3] 目前PS3 所運行的Folding@Home WU為相對簡易且侷限之任務

What type of calculations the PS3 client is capable of running? The PS3 right now runs what are called implicit solvation calculations, including some simple ones (sigmodal dependent dielectric) and some more sophisticated ones (AGBNP, a type of Generalized Born method from Prof. Ron Levy's group at Rutgers). In this respect, the PS3 client is much like our GPU client. However, the PS3 client is more flexible, in that it can also run explicit solvent calculations as well, although not at the same speed increase relative to PC's. We are working to increase the speed of explicit solvent on the PS3 and would then run these calculations on the PS3 as well. In a nutshell, the PS3 takes the middle ground between GPU's (extreme speed, but at limited types of WU's) and CPU's (less speed, but more flexibility in types of WU's) [emphasis added].

PS3目前運行的WU為implicit solvation calculations，相對行之有年的PC WU而言範圍相對有所侷限。在未來PS3將可運行explicit solvent calculations 的WU，但性能表現將不如目前相對PC表現來得那嚜優異。此外目前來自ATI GPU X19系列的最高速Folding@Home 方案(約為PS3 Cell F@H兩倍性能)所接收的WU範圍更為侷限。.

GPU 咚惚萈S3 Cell更為簡易的WU，給PC用的是全種類的WU，相對性能負擔也越大。

PC在跑咚愕臅r候可以做其他事情
PS3不行

你连基本概念都没有。

总觉得Home是个“很未来”的东西，不大靠谱。
真这样带宽还不得爆了。

这个 咋说呢   SONY愿意  完全可以作到滴 [s:248]

难道SONY又缩水了?

那么有兴趣 亲自去参加一下分布式计算~

樓上完全誤解。

顯卡GF8800 518G Flops的性能在Folding @Home完全得不到應用，純CPU計算。
Folding Home支持的GPGPU方案為ATI X1900/1950系列，不歸屬在Windows PC中。

RSX 1.8T Flops，純屬YY一場。這年頭還有人把PS3當神機，從還有人yy數字就可見一番。
