is there a way in the runtime to tell whether the runtime was
initialized through a call to the kmp or gomp interface? As I understand
the initialization, this is currently not possible.
A way to implement this would be to pass a flag through
__kmp_get_global_thread_id_reg to __kmp_do_serial_initialize. Would this
The background for this question is the different behavior regarding
OMPT callbacks. Specifically, gomp has currently no way to provide a
callback for the single-end event.
Following the specification, the runtime should return
ompt_set_sometimes instead of ompt_set_always when registering
ompt_callback_work knowing that the application uses the gomp interface.
