Description

This is an internal function exported for those people who know what they are doing.

This function hard codes responses to a set of environments, like detecting snowfall, or running on a cluster where "OMP_NUM_THREADS" is set or otherwise returning 1 or 2 cores to avoid consuming all the resources on CRAN's test machines during release cycles.

This makes it not suitable for getting the number of available threads.

To get the number of cores available locally you want omxDetectCores or perhaps the detectCores function in the parallel package.
