Yep, there are indeed two progress threads running - and no, you cannot disable
them. They are, however, “blocked” so they aren’t eating any cycles during
normal operation unless an event that requires their attention wakes them up.
So they shouldn’t interfere with your app.

Hi:
When running a simple MPI program in the form of:
int main()
{
...
MPI_Init();
...
sleep(10);
...
MPI_Finalize()
;
...
}
Two threads, additionally to the master, can be seen when using gstack:
Thread 3 (Thread 0x7f2238a6c700 (LWP 106578)):
#0 0x7f223a869783 in epoll_wait () f
