Terry,
was this with the trunk or v1.3? If it was the trunk, was it before
r19929 was applied? The reason I ask is because r19929 should remove all
error messages related to 'non-existing communictors'. Hierarch btw. is
not the cause for the error messages even before that, it just exposes
it more frequently...
Thanks
Edgar

I am seeing the message "Dropped message for the non-existing
communicator" when running hpcc with np=124 against r19845. This seems
to be pretty reproducible at np=124. When the job prints out the
message above some set of processes are in an MPI_Bcast and the 15
processes reporting the message are stuck in MPI_Barrier.
I am not sure how related this is to #1408 since I am not invoking the
hierarchical collectives. I just wanted to see if anyone else has tried
to run hpcc at such an np size with any success.
My next steps are to try to run this with the latest trunk and to narrow
down the failing case.
