PAPI_thread_init(3) PAPI PAPI_thread_init(3)
Initialize thread support in the PAPI library.
Pointer to a function that returns current thread ID.
PAPI_thread_init initializes thread support in the PAPI library.
Applications that make no use of threads do not need to call this routine.
This function MUST return a UNIQUE thread ID for every new thread/LWP created.
The OpenMP call omp_get_thread_num() violates this rule, as the underlying
LWPs may have been killed off by the run-time system or by a call to omp_set_num_threads() .
In that case, it may still possible to use omp_get_thread_num() in
conjunction with PAPI_unregister_thread() when the OpenMP thread has finished.
However it is much better to use the underlying thread subsystem's call,
which is pthread_self() on Linux platforms.
