Implementation-Specific Information of OpenMP

This appendix details the implementation specific details of OpenMP C and C++ Application Program Interface Version 1.0 - October 1998 (available from: http://www.openmp.org)

In the absence of an explicitly defined OMP_SCHEDULE environment variable, this implementation uses static scheduling for loops with schedule(runtime).

In the absence of an explicitly defined schedule clause, the default is static scheduling.

If you do not explicitly specify the number of threads in a team through either the opm_set_num_threads function or the OMP_NUM_THREADS environment variable, the default is 1.

If you do not explicitly specify whether dynamic adjustment of threads is enabled through either the omp_set_dynamic function or the OMP_DYNAMIC environment variable, the default is enabled dynamic adjustment.

Nested parallelism is not supported and is disabled by default.
