I just checked the head of both the master and 3.0.x branches, and they both
work fine:
$ mpirun --map-by ppr:1:socket:pe=1 date

Hi Ralph,
the problem occurs when you add --host with a different machine. Without
--host or with "--host " everything works well.
pc03 fd1026 111 which mpiexec
/usr/local/openmpi-3.0.0_64_gcc/bin/mpiexec
pc03 fd1026 112 mpiexec -np 2 --map-by ppr:1:socket:pe=1 date
[pc03:09373] SETTING BINDING
Nope - works that way too (running from rhc001):
$ mpirun -H rhc002:24 --map-by ppr:1:socket:pe=1 date
