Shell, Environment, and Other Software Settings

KMP_AFFINITY=granularity=fine,compact
The value for the environment variable KMP_AFFINITY affects how the threads are distributed across processors.
Specifying granularity=fine binds threads to individual thread contexts, i.e. avoids migration of OpenMP threads between multiple thread contextss on one core.
Specifying compact binds the OpenMP thread n+1 on a free thread context as close as possible to the thread context where the OpenMP thread n was bound.
OMP_DYNAMIC=FALSE
OMP_DYNAMIC=[ 1 | 0 ] Enables (1) or disables (0) the dynamic adjustment of the number of threads.
OMP_NESTED=FALSE
OMP_NESTED=[ 1 | 0 ] Enables (1) or disables (0) nested parallelism.
OMP_STACKSIZE
The OMP_STACKSIZE environment variable indicates the stack size of threads created by the OpenMP run time.
