Pull request overview
This PR ports the “xstride / excl-stride” communicator-setup updates from the
driver-mct implementation into driver-moab, ensuring exclusive-task groups
are initialized early enough to be honored when creating component
communicators.
Changes:
- Add early initialization of exclusive-stride MPI groups (via
xcount+
comp_exstride_init) prior tocomp_comm_initcalls. - Add helper subroutine
comp_exstride_initto build/store excl-stride groups. - Update
seq_comm_setcommto exclude exclusive-task groups across all comm IDs
(not just IDs created earlier).
