PAPI_unregister_thread(3) PAPI PAPI_unregister_thread(3)
Notify PAPI that a thread has 'disappeared'.
PAPI_ENOMEM Space could not be allocated to store the new thread information.
PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
PAPI_ECMP Hardware counters for this thread could not be initialized.
PAPI_unregister_thread should be called when the user wants to shutdown a particular
thread and free the associated thread ID. THIS IS IMPORTANT IF YOUR THREAD LIBRARY REUSES
THE SAME THREAD ID FOR A NEW KERNEL LWP. OpenMP does this. OpenMP parallel regions, if
separated by a call to omp_set_num_threads() will often kill off the underlying kernel
LWPs and then start new ones for the next region. However, omp_get_thread_id() does not
reflect this, as the thread IDs for the new LWPs will be the same as the old LWPs. PAPI
needs to know that the underlying LWP has changed so it can set up the counters for that
new thread. This is accomplished by calling this function.
