Intel OpenMP run-time lib default configuration

Intel OpenMP run-time lib default configuration

Hello:

What is the default openmp runtime configuration ( number of threads, scheduling policy, and chunk size) for the intel openmp library?

Thanks,

Hello!

You can use KMP_SETTING=1 environment variable to get internal variable values used by the OpenMP RTL as well as OMP*, KMP* environment variables set by you (if any).

As for the number of threads - if no explicit settings were used (OMP_NUM_THREADS env var or num_threads clause) the RTL will use the number of threads equal to the number of available hardware threads.

Thank you.
