Dear LAM/MPI users and developers,
I am very satisfied with the SSI "tm" module which allows to "lamboot"
easily on the nodes allocated by Pbs, without using rsh or ssh.
But at times I would like to "cheat it" somehow. Here is why.
Four of our nodes are equipped with Gigabit interconnections (they have
Gigabit cards connected to a four-way Gigabit switch).
So each one has two names, say "node1, node1-1000"... "node4,
node4-1000".
If I submit a job to Pbs with a special property ("fastcomm"), I am sure
to land on these nodes.
The nodes declared to Pbs are "node1"..."node4".
So if I use the tm module to "lamboot", it will enlist "node1"...
"node4", and thus the network interface that will be used for the
communications will be the standard (slow) one.
Is it possible to cheat the tm module so that it enlists instead
node1-1000... node4-1000?
Thanks for any tip,
