Problems of PREFETCH instruction on UltraSparc T1

2007-08-21 Thread jiaqi zhang
Hi, everyone, I don't really know if it is proper to post this topic here. In order to accelerate our applications, I adopted the PREFETCH instruction of UltraSparc. However, the results are not expected: the one with prefetch works even a little bit slower. The whole program is listed below. I r
