OpenMP Special Functions

Artificial functions are constructed and put onto the User mode call stacks reflecting events in which a thread was in some state within the OpenMP runtime library. The following artificial functions are defined; each is followed by a description of its function:

• <OMP-overhead> – executing in the OpenMP library

• <OMP-idle> – slave thread, waiting for work

• <OMP-reduction> – thread performing a reduction operation

• <OMP-implicit_barrier> – thread waiting at an implicit barrier

• <OMP-explicit_barrier> – thread waiting at an explicit barrier

• <OMP-lock_wait> – thread waiting for a lock

• <OMP-critical_section_wait> – thread waiting to enter a critical section

• <OMP-ordered_section_wait> – thread waiting for its turn to enter an ordered section
