I am using multiprocessing library of python and also emcee which also uses different threads to implement MCMC. The problem is that even when I close the pool still it seems python uses the processors and slows down the cores and I have no idea what is the efficient way to release the cores after the job is done. Could anybody give me an idea of what I should do?
Update: My code has been already posted here.

关闭 aPool并不会阻止它工作,它只会阻止将新的工作项添加到其中

关()

防止任何更多的任务被提交到池中。完成所有任务后,工作进程将退出。

因此,如果您有很多排队的任务,关闭它们Pool不会对资源使用产生任何影响 - 所有工作人员都会继续使用这些排队的任务,直到它们消失。如果您想立即中止所有工作项,则必须使用pool.terminate

终止()

立即停止工作进程而不完成未完成的工作。当池对象被垃圾回收时,terminate()将立即调用。
