Right now, I do believe that if you list a host more than once, it bumps the slots count. This is somewhat inelegant, but something like: shell$ mpirun -host node1 -host node1 ... Same as: shell% mpirun -host node1,node1 ... Will make node1 have a slot count of 2. We can certainly change this, though -- it wasn't implemented simply because I didn't think of this case. :-) -- Jeff Squyres Server Virtualization Business Unit Cisco Systems
