However, the default thread count seems to be implementation defined, and as far as I can tell there is no function included in OpenMP (?) that can tell …
WebOpenMP并行编程模式 OpenMP是基于线程的并行编程模型。 OpenMP采用Fork-Join并行执行方式： zOpenMP程序开始于一个单独的主线程（Master Thread），然后主线程一直串行执行，直到遇见第 一个并行域(Parallel Region)，然后开始并行执行并行 区域。其过程如下： WebSelect the Analyze OpenMP regions option, if it is not pre-selected (see the Details section to confirm).
