[argobots-discuss] Program aborting in ABT_finalize (ABTI_pool_release failed)

[Dorier, Matthieu]

Hi,

I’m getting this error in a program, when calling ABT_finalize:

../src/include/abti_pool.h:238: ABTI_pool_release: Assertion `ABTD_atomic_acquire_load_int32(&p_pool->num_scheds) > 0' failed.

The program only uses the primary ES, it does not create additional ES, however it does replace the primary ES’s pool and scheduler by creating a fifo_wait MPMC pool and passing it to ABT_xstream_set_main_sched_basic, with ABT_SCHED_BASIC_WAIT as sched_predef.

I’m using Argobots 1.0. I haven’t tested with other versions of Argobots. I’m sure I must be doing something wrong somewhere in my code. Could you tell me what I could look for that would lead to such an error?

For additional information, here it the stack trace when the error happens:
