positively
confirm it is actually running - though I have some indication that
it is.
This is probably my fault somehow; I can look into this but not
immediately. I'm guessing this is related to the IOF fix that I put
in last week sometime. If you can deal without io from the
COMM_SPAWN children for a little while, I can look at it in a few
days...
2. if running on multiple hosts, I see the output from the child
processes,
but mpirun "hangs" in MPI_Comm_disconnect. A ctrl-C is able to kill
the
entire job.
I can't comment on this one...
Any ideas on what might have happened? This was all working not
that long
ago...can't swear to an r-level at the moment, but am hoping
someone has an
idea before I start having to blindly work backwards to find out
what broke
it.
Thanks
Ralph
