用OpenBlas时,OPENBLAS_NUM_THREADS设置为最大,让CPU负载跑满,并不能大幅提高速度,这是为什么?一直没搞明白。 看到Caffe上有人提交了《Parallel version of caffe for CPU based on OpenMP》,据说在CPU模式下有高达10倍的但似乎为了减少代码维护的复杂性,Caffe官方并没有接受这个PR。根据Caffe的作者Yangqing Jia的回...

一般来说,OpenBLAS FAQ说 OpenBLAS 的多线程可能与主程序的多线程“冲突”,并建议OPENBLAS_NUM_THREADS=1在这种情况下进行设置。然而,常见问题解答条目未能提供任何详细信息来验证其声明,因此它很可能已过时!根据https://github.com/obspy/obspy/wiki/Notes-on-Parallel-Processing-with-Python-and-ObsPy,这种“冲突”...

OpenBLAS does not set processor affinity by default. On Linux, you can enable processor affinity by commenting the line NO_AFFINITY=1 in Makefile.rule. But this may causethe conflict with R parallel. On Loongson 3A. make test would be failed because of pthread_create error. The error code...

特别是,你可以查看 driver/others/dynamic.c 或driver/others/parallel.c 等文件,这些文件中通常包含与线程创建和管理相关的代码。 4. 检查 pthread_create 失败的可能原因 pthread_create 失败可能由多种原因引起,包括但不限于: 系统资源不足:如上面提到的CPU、内存不足。 线程数限制:系统或用户级别的线程数限制...
