Hello, 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 I cannot find the appropriate syntax for specifying a user in machinefile.txt... Thanks in advance, Olivier
