thread.error: can't start new thread 方案:使用Thread中的event,并进行上锁设置来解决。 原因:这个是由于每台计算机能进行的并行是有上限的,经过测试本机的上限为1023个左右(win7 64位,i3 2核4线程),可以进行设置提高上限,但我觉得此处没有必要,也不方便扩展,所以想自行定义一个并行的上限数进行处理。 参考:...
参考:在多次百度无果之后,选择了google,查看了国外的一些评论和解决方案,在google学术中搜索“python thread number limit”,下载了此篇pdf,在13-14页中找到了解决方案,果然是老外做的东西,老外更懂啊。 http://python-ray.googlecode.com/hg-history/425d613ba8a2c7bd367b573018df45e5ec474428/doc/PyThreads.p...
用 Python 做到每秒处理上百万次 HTTP 请求，可能吗？也许不能，但直到最近，这已成为现实。

Currently,threadpoolctlhas support forOpenMPand the mainBLASlibraries. However it can also be used to control the threadpool of other native libraries, provided that they expose an API to get and set the limit on the number of threads. For that, one must implement a controller for this libr...
