更新到6.04后执行率下降了,当然不知道是不是个人问题,按官网论坛里介绍调整后利用率上去了CPU占用率也高多了,另外就是HD7750的显卡和HD6770的显卡运行起来总时间差不多,7750略快,但是在官网记录里显示的有点不明白这里是两台机器的配置,HIS刀卡HD 7750 900/1250,,蓝宝HD 6770 800/1200

6770运行记录,,CPU时间和运行时间,这里是几次按官网优化的记录,感觉像是牺牲CPU的处理性能提高了总运行时间,但是CPU也被占用很多

HD7750的,之前我也发帖子问执行率只有50%,然后优化了就99%了

优化的设置
verbose=1
items_per_kernel=20
kernels_per_reduction=8
threads=8
sleep=1
build_options=-Werror
--------忘说重点了实际上两种卡性能差不多吧,但是感觉还是有很明显的差距,不知道是不是架构造成的,还是其它什么方法可以优化,大概就是尽量节约CPU性能提高GPU的运算效率,减少总运行时间之类的方法。。。
