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...
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:...
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...

1.1 什么是线程(thread)? 线程是操作系统能够进行运算调度的最小单位。它被包含在进程之中,是进程中的实际运作单位。一条线程指的是进程中一个单一顺序的控制流,一个进程中可以并发多个线程,每条线程并行执行不同的任务 A thread is an execution context, which is all the information a CPU needs to execute...
struct _ceval_runtime_state { int recursion_limit; /* Records whether tracing is on for any thread. Counts the number of threads for which tstate->c_tracefunc is non-NULL, so if the value is 0, we know we don't have to check this thread's c_tracefunc. This speeds up the if ...

类似于进程,每个线程也有自己的堆栈,不同于进程,线程库无法利用时钟中断强制线程让出CPU,可以调用thread_yield运行线程自动放弃cpu,让另外一个线程运行。 线程通常是有益的,但是带来了不小程序设计难度,线程的问题是: 1. 父进程有多个线程,那么开启的子线程是否需要同样多的线程 ...
