此时,你可能会在程序输出中看到类似“omp_num_threads environment is not set. defaulting to 1 thread”的警告信息,提示你环境变量未设置,因此将默认使用单个线程。 提供设置omp_num_threads环境变量的方法: 你可以通过以下几种方法来设置omp_num_threads环境变量: 在Unix/Linux系统上: 你可以在运行程序之前,在...

The number of threads set using thenum_threadsclause takes precedence over that set using theomp_set_num_threadsfunction. The number of threads set using theomp_set_num_threadsfunction takes precedence over that set using the OMP_NUM_THREADS environment variable. The number of threads set using ...
If you do not set theOMP_NUM_THREADSenvironment variable, the number of processors available is the default value to form a new team for the first encountered parallel construct. By default, any nested constructs are run by one thread. ...

If it is not set, the library checks for OMP_NUM_THREADS; if it set, that value is used. If it is not set, then the number of total threads (not the concept, but the single user-facing number) is left unspecified. Indeed. Now, while I can see that having dedicated environment ...
We have R linked to OpenBLAS which by default uses all threads on a server for calculations such as matrix multiplication. Setting an environment variables like export OMP_NUM_THREADS=1 restores expected behvious for R command-line, but ...
