OpenMP nested parallelism

Accelerated Computing HPC Compilers Legacy PGI Compilers

I’ve tried to specify nested parallelism using both setting the OMP_NESTED=true environment variable, and calls to OMP_SET_NESTED(.true.).

Neither appears to work. For example, immediately after the call to OMP_SET_NESTED(.true.), a call to OMP_GET_NESTED() returns a “false”.

I’m running on Red Hat Linux on an x86_64.

Any ideas?

Hi tsalem,

Support for OMP nested parallelism will be available in the PGI 2012 (12.0) release.
