Folks,
i made a trivial test
echo hello | mpirun -np 1 cat
and with v2.x and v1.10, the output is "hello" as expected
but with master, there is no output at all (!)
i was able to fix that with the dirty workaround below.
the root cause (on master) is that orte_cmd_options.stdin_target is NULL.
fwiw, i could not see such option in the output of ompi_info --all
as far as i understand, such option is registered in
orte/mca/schizo/ompi/schizo_ompi.c and/or orte/orted/orted_main.c
i tried various things, but was unable to have this option registered.
can someone more familiar with this part please have a look ?
Cheers,
Gilles
