[OMPI devel] Multiworld MCA parameter values broken

[Tim Prins]

Hi,

Commit 16364 broke things when using multiword mca param values. For 
instance:

mpirun --debug-daemons -mca orte_debug 1 -mca pls rsh -mca pls_rsh_agent 
"ssh -Y" xterm

Will crash and burn, because the value "ssh -Y" is being stored into the 
argv orted_cmd_line in orterun.c:1506. This is then added to the launch 
command for the orted:

/usr/bin/ssh -Y odin004  PATH=/san/homedirs/tprins/usr/rsl/bin:$PATH ; 
export PATH ; 
LD_LIBRARY_PATH=/san/homedirs/tprins/usr/rsl/lib:$LD_LIBRARY_PATH ; 
export LD_LIBRARY_PATH ; /san/homedirs/tprins/usr/rsl/bin/orted --debug 
--debug-daemons --name 0.1 --num_procs 2 --vpid_start 0 --nodename 
odin004 --universe tpr...@odin.cs.indiana.edu:default-universe-27872 
--nsreplica 
"0.0;tcp://129.79.240.100:40907;tcp6://2001:18e8:2:240:2e0:81ff:fe2d:21a0:40908" 
--gprreplica 
"0.0;tcp://129.79.240.100:40907;tcp6://2001:18e8:2:240:2e0:81ff:fe2d:21a0:40908" 
-mca orte_debug 1 -mca pls_rsh_agent ssh -Y -mca 
mca_base_param_file_path 
/u/tprins/usr/rsl/share/openmpi/amca-param-sets:/san/homedirs/tprins/rsl/examples 
-mca mca_base_param_file_path_force /san/homedirs/tprins/rsl/examples

Notice that in this command we now have "-mca pls_rsh_agent ssh -Y". So 
the quotes have been lost, as we die a horrible death.

So we need to add the quotes back in somehow, or pass these options 
differently. I'm not sure what the best way to fix this.

Thanks,

Tim
