性能 function (of a machine, etc.); performance; property; nature; [中医] property and action 飞机性能 airplane characteristics; 反应堆性能 reactor behaviour; 金属的性能 metal properties; 性能优良 high performance; 这种机器性能良好。 this kind of machine performs satisfactorily. 你对你的新车的性能满意吗? are you satisfied with the performance of your new car
Peak performance is a consequence of matching your individual strengths with the requirements of an event 达到峰值性能是你个人的强项与某次比赛的要求匹配的结果。
With the advance in hpc , many high performance computers are emerged and used . the computers ’ peak performances increase with a continuous and rapid way 随着高性能计算的发展,各种高性能计算机不断涌现并得到广泛发展,机器的峰值性能不断提高。
But the sustained performances achieved by real applications do not increase in the same scale as the machine ’ s peak performances do . the gaps between the applications ’ sustained performances and the machines ’ peak performances are widening 但是,实际应用程序获得的持续性能并未随着机器峰值性能的提高而同比例提高,两者的差距日益扩大。
There are some distance between the tested performances and theoretical peak values because of high systematic cost and access memory delay , but they all satisfy the performance requirements of the confidential server 由于系统开销和访存延时等原因,通过操作系统进行的以上测试的性能虽然与理论峰值性能间存在一定差距,但均达到高性能密码服务器的性能要求。
In real applications , the gap between the applications ’ real performance and the machines ’ peak performance is widening . the performance analysis tool is needed to solve this problem and find out performance bottlenecks quickly . then users can develop high performance programs that execute efficiently on high performance computer 在实际应用中,高性能计算领域面临实用性能与峰值性能差距日益增大的问题,因此需要构建并行程序性能分析工具,使得用户能够快速定位性能瓶颈,从而开发出高质量的并行代码,并在相应的高性能计算机上高效执行。
