4. Non-SMPlib-API Routines

The next two routines are included in v2.2+, but they are not part of the SMPlib v2 API. The two routines are intended for calling by non-SMP programs.

void SMP_Pinit(int nprocs, int myid);

SUBROUTINE SMP_PINIT(NPROCS, MYID)
INTEGER NPROCS, MYID

• performs pin-to-node for process MYID (0..nprocs-1), assuming a fixed number of threads per process (defined by OMP_NUM_THREADS). The environment variable SMP_PINIT is still checked for the actual activation. Note: this function should NOT be used together with SMP_Fork() or SMP_Forkthread().
• error code: SMP_ERR_NODE, SMP_ERR_PINIT

void SMP_Pinit_thread(int nprocs, int myid, int nthreads[]);

SUBROUTINE SMP_PINIT_THREAD(NPROCS, MYID, NTHREADS)
INTEGER NPROCS, MYID, NTHREADS(0:*)

• same as SMP_Pinit except that it accepts a variable number of threads per process. The same restrictions for SMP_Pinit apply to this function.
• error code: SMP_ERR_NODE, SMP_ERR_PINIT
