Thanks,
Daniel

Daniel,
i double checked this and i cannot make any sense with these logs.
if coll_ml_priority is zero, then i do not any way how
ml_coll_hier_barrier_setup can be invoked.
could you please run again with --mca coll_base_verbose 100
with and without --mca coll ^ml
Cheers,
Gilles

Daniel,
ok, thanks
it seems that even if priority is zero, some code gets executed
I will confirm this tomorrow and send you a patch to work around the
issue if that if my guess is proven right
Cheers,
Gilles

MCA coll: parameter "coll_ml_priority" (current value: "0", data
source: default, level: 9 dev/all, type: int)
Not sure how to read this, but for any n>1 mpirun only works with
--mca coll ^ml
Thanks for helping

This is really odd...
you can run
ompi_info --all
and search coll_ml_priority
it will display the current value and the origin
(e.g. default, system wide config, user config, cli, environment
variable)
Cheers,
Gilles

No, that's the issue.
I had to disable it to get things working.
That's why I included my config settings - I couldn't figure
out which option enabled it, so I could remove it from the
configuration...

Daniel,
ML module is not ready for production and is disabled by
default.
Did you explicitly enable this module ?
If yes, I encourage you to disable it
Cheers,
Gilles

for n=1
mpirun -n 1 ./hello
it works correctly.
for n>1 it segfaults with signal 11
used gdb to trace the problem to ml coll:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6750845 in ml_coll_hier_barrier_setup()
from <path to openmpi 1.8.5>/lib/openmpi/mca_coll_ml.so
running with
mpirun -n 2 --mca coll ^ml ./hello
works correctly
using mellanox ofed 2.3-2.0.5-rhel6.4-x86_64, if it's
at all relevant.
