Run-Time Library Routines
OMP GET NUM THREADS: Returns the number of threads that are currently in the team executing the parallel region from which it is called.
Format |
| int omp get num threads(void) |
- If this call is made from a serial portion of the program, or a nested parallel region that is serialized, it will return 1.
- The default number of threads is implementation dependent
OMP GET MAX THREADS: Returns the maximum value that can be returned by a call to the OMP GET NUM THREADS function.
Format |
| int omp get max threads(void) |
- This routine can only be called from the serial portion of the code.
- This call has precedence over the OMP NUM THREADS
OMP GET THREAD NUM: Returns the thread number of the thread, within the team, making this call. This number will be between 0 and OMP GET NUM THREADS-1. The master thread of the team is thread 0
Format |
| int omp get thread num(void) |
- If called from a nested parallel region, or a serial region, this function will return 0
OMP GET THREAD LIMIT: New with OpenMP 3.0. Returns the maximum number of OpenMP threads available to a program.
Format |
| int omp get thread limit(void) |
OMP GET NUM PROCS: Returns the number of processors that are available to the program.
Format |
| int omp get num procs(void) |
