You can use the relative host syntax, but you cannot use a "pernode"
or "npernode" option when you have more than one application on the
cmd line. You have to specify the number of procs for each
application, as the error message says. :-)
IIRC, the reason was that we couldn't decide on how

page near the top is the simple example:
mpirun -pernode -host +n1,+n2 ./app1 : -host +n3,+n4 ./app2

i.e, 16 processors on 4 nodes. from which I can parse into file(s) as
desired. If I w
