1. 解释blas_thread_init: rlimit_nproc -1 current, -1 max的含义 当你在使用Docker容器运行包含OpenBLAS库的程序时,可能会遇到这样的日志输出:blas_thread_init: rlimit_nproc -1 current, -1 max。这条信息来自于OpenBLAS库在初始化多线程支持时的日志记录。 rlimit_nproc是一个资源限制(Resource Limit),用于...

通过ulimit限制最大进程数目 说起进程数限制,大家可能知道ulimit的nproc这个配置:当调用fork创建一个进程时,如果该UID用户的进程数之和大于等于进程的RLIMIT NPROC值时,fork调用将会失败返回。 遗憾的是,默认情况下,Docker容器中启动的进程是root用户下的,而ulimit的nproc参数无法对超级用户进行限制。所以,准确地说,目前...

参数大致意思是,在当前所属用户 namespace 下允许该用户创建的最大的 PID,意思应该是最大进程吧,等同于参数 ulimit -u 的值,由内核初始化而定义的,具体算法应该是(init_task.signal->rlim[RLIMIT_NPROC].rlim_max = max_threads/2)。 kernel.cad_pid = 1 ...
