We have a user who's hitting a hang in MPI_Allgather that totalview is
showing is in a tuned collective operation.
How do we disable the use of tuned collectives? We have tried setting
the priority to 0 but maybe that wasn't the correct way:
mpirun -mca coll_tuned_priority 0 ...
Should it have been a higher number or is there another param that
should be set?
Thanks,
david
