Environment variables for parallel processing

The XLSMPOPTS environment variable sets options for program run time using loop parallelization. Suboptions for the XLSMPOPTS environment variables are discussed in detail in XLSMPOPTS.

If you are using OpenMP constructs for parallelization, you can also specify runtime options using the OMP environment variables, as discussed in Environment variables for OpenMP.

When runtime options specified by OMP and XLSMPOPTS environment variables conflict, OMP options will prevail.
