OMP_DYNAMIC=TRUE | FALSE environment variable

The OMP_DYNAMIC environment variable enables or disables dynamic adjustment of the number of threads available for running parallel regions.

If it is set to TRUE, the number of threads available for executing parallel regions can be adjusted at run time to make the best use of system resources. For more information, see the description for profilefreq=num in XLSMPOPTS.

If it is set to FALSE, dynamic adjustment is disabled.

The default setting is TRUE.
