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/

The OMP_NUM_THREADS environment variable sets the default number of threads to use during execution, unless that number is explicitly changed by calling the omp_set_num_threads library routine or by an explicit num_threads clause on a parallel directive.The...

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 ...

This call has precedence over theOMP_NUM_THREADSenvironment variable. The default value for the number of threads, which may be established by callingomp_set_num_threadsor by setting theOMP_NUM_THREADSenvironment variable, can be explicitly overridden on a singleparalleldirective by specifying thenum...
