Shell, Environment, and Other Software Settings

MTEXCLUSIVE
If set to "Y", additional memory allocation buckets will be created, so that threads will not need to share buckets unless more than 2*NCPUS threads are created. This variable is used by mtmalloc.

OMP_NUM_THREADS
Sets the number of threads to use in OpenMP parallel regions.

SUNW_MP_PROCBIND
Binds threads in an OpenMP program to the virtual processors enumerated in the assignment. Can also be set to TRUE, which casues threads to be bound in a round-robin fashion.

SUNW_MP_THR_IDLE
Specifies whether idle threads should SLEEP or SPIN.

STACKSIZE=<n>
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.

ulimit -s <n>
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
Note that the "heap" and the "stack" share space; if your application allocates large amounts of memory on the heap, then you may find that the stack limit should not be set to "unlimited". A commonly used setting for SPEC CPU2006 purposes is a stack size of 128MB (131072K).
