T****O 发帖数: 407 | 1 Parallels针对Windows虚拟机优化更好,那些采用DirectX的软件,在Parallels支持下
更流畅。VMWare差一些,Windows下面任务一重,明显感觉迟滞。他们共性是吃内存很
厉害,强占硬盘吞吐。建议Mac内存增至8GB以上,把虚拟盘文件放在SSD上。 |

T****O 发帖数: 407 | 2 这年月Parallels撑起来的虚拟机居然还有换盘操作?你的SAS版本是DOS,Win95, 还是
NT4?
实在不行你找个PC,用匹配的操作系统装SAS,测试通过之后联机,用Parallels导入功
能。也许需要先把PC系统转换成虚拟硬盘文件,记不清了,反正不麻烦,就是很耗时间

100%cpu使用率别人还不疯掉了。
我在2,4,6核的机器上都试过,全是100%, 而且无法调整。
msdn上说parallel computing是代替thread pool的。如此表现我们就是有100个胆也不
敢用啊。还是thread poolx先混着吧。 |

S***k 发帖数: 370 | 9 在c#里一般不能超过cpu数目,否则cpu usage可能会太高。影响background program

java的parallelism似乎也是和cpu数目有关,但是可以设到100的量级。java的
parallelism 到底是个什么?太高的话会不会有问题? |
|
s***o 发帖数: 2191 | 10 我的理解parallelism强调的是同时进行(simultaneous execution)。一个典型例子比
如list.map操作,list 可以split成几段,在不同的core上处理完再合并。Java
ForJoinPool parallelism default level就是cpu数量,设置成100不知会对
