[padb-users] padb stalls with no output.

[Rahul Nabar]

I'm stumped, since I had a perfectly running padb just a day ago and
now on the same system it won't produce any output at all. I'm sure
it's me doing something terribly silly, but can't figure out what!

[rpnabar at eu001 test]$ whoami

[rpnabar at eu001 test]$ NP=64;mpirun  -np $NP --host
eu001,eu002,eu003,eu004,eu005,eu006,eu007,eu008   -mca btl
openib,sm,self    /opt/src/mpitests/imb/src/IMB-MPI1 -npmin $NP
gather

[wait for test to stall]
[then in another shell window onto the same node]

[rpnabar at eu001 ~]$ whoami
rpnabar

[rpnabar at eu001 ~]$ /opt/sbin/bin/padb --all --stack-trace --tree
--config-option rmgr=orte -v

[gather test is still stalled in the other window]

Any ideas what could be going on here? What's even more confusing is
that ompi-ps produces  no output either (see below)! Have I broken my
mpi install somehow? But that wouldn't make sense since the actual mpi
tests are running file. Again, the symptoms are so bizarre that I
suspect I am the one doing something stupid. But can't figure out what
it is!!

[rpnabar at eu001 ~]$ ompi-ps
[No output]
