所以Splinter Cell : Conviction沒辦法在PS3上發售。
但是在此同時,8/14號,三個PNNL的專家在DDJ發表了一篇文章。

Programming the Cell Processor
It may be tricky, but the performance gains are worth the effort
最佳化之後,單顆CELL的性能達到了Woodcrest的22倍,單顆SPE的性能最高可以達到1.4 ~ 4.75倍,足以和256顆CPU的BlueGene/L對抗....
好吧,程式碼變成20倍長了。XD
總之,人家用的演算法是BFS。 _A_
還附上完整的optimize guide....
原文:Some techniques (loop unrolling, function inlining, SIMDization) are familiar; others (bulk synchronous parallelization, DMA traffic scheduling, overlapping of computation and transfers) are less so.. |
