Hi,

I am using openmpi on several machines which have different user
accounts and I cannot find a way to specify the login for each
machine in the machinefile passed to mpirun.
The only solution I found is to use the -host argument of mpirun,
such as:
mpirun -np 2 --host user1@machine1,user2@machine2 MyProgram
which is very inconvenient with a lot of machines.
Is there a way to do the same using a machinefile text? :
mpirun -np 2 -machinefile machinefile.txt MyProgram
the program can be found at the same location on all machines?
When you use ssh as startup, this can be coded in ~/.ssh/config:
Host node001
User fubar
Hostname headnode.my.cluster.test
Host node002
User foo
Host node003
User bar
-- Reuti
I cannot find the appropriate syntax for specifying a user in
machinefile.txt...
Thanks in advance,
Olivier
