[运算]请教CST多核计算

请问在CST中如何设置多核并行计算，我用的是双CPU，每个4核，但显示只用了一个核 .. Ay[6rU

现在是自动认多核的吧，不用设置也可以默认吧

CST MWS帮助文件《Acceleration》。

自动识别的，不过跟求解器有关，有的能满核，有的不行

也分计算的阶段，有的阶段只用一个核

好像对多线程支持的不好

只认物理核心不认超线程

Why are only half of the available processor cores used by the CST solvers? (hyperthreading) (Faq #348) j7:r8? G

Newer processors have a feature called hyperthreading, i.e., the processors have not only the so called physical cores but they also have virtual cores which provide some limited functionality but are shown in the Windows Task Manager as normal processor cores. This means that you will see 24 processor cores in the Task Manager on a machine which has 12 physical processor cores with hyperthreading enabled. M`q|GY

For some type of applications hyperthreading can improve the performance. However, the performance of the CST solvers suffers if they run not only on physical processor cores but also on the virtual cores. For this reason the solvers are only started on the physical processor cores found on the machine. The virtual cores are ignored. This is the reason why you see only 50% processor load in the Task Manager.

my god！ 真的不支持新版cpu的超线程技术！？求解器的性能至少损失20%-30%！对之前旧版cpu的超线程技术支持的很好，为何现在不行了？CST的开发人员在用旧机器吗？摩尔定律尚未过时，非常期待CST能够早日加入对新版cpu的超线程技术的支持。
