Issue: MPI is not launching the correct tasks on the correct node with 1.10.2.

Symptom: When running a mpi rum on 1.10.2  you may see the following:

mpirun hostname 
-------------------------------------------------------------------------- 
A request for multiple cpus-per-proc was given, but a directive 
was also give to map to an object level that has less cpus than 
requested ones: 

#cpus-per-proc: 1 
number of cpus: 0 
map-by: BYSOCKET:NOOVERSUBSCRIBE 

Please specify a mapping level that has more cpus, or else let us 
define a default mapping that will allow multiple cpus-per-proc. 
-------------------------------------------------------------------------- 

Solution: This is a known issue (https://www.open-mpi.org/community/lists/users/2016/01/28393.php ). Pleasr upgrade OpenMP to 1.10.3rc1 or later.
