Hi
we have a cluster on which several people want to run their lam/mpi jobs
as themselves. alas, this appears to be impossible.
we have a special "lampi" user and lamboot is run as "lampi".
we have a daemon (run as lampi) who accepts "job requests" from
individuals, queues them, and runs them using mpirun one by one.
it works just fine, except that the jobs are run as "lampi".
we want the jobs to be run as the owner, so we tried to have the daemon
run them as "sudo -u <user> mpirun ...".
this fails with the message

-----------------------------------------------------------------------------
It seems that there is no lamd running on the host <main-cluster-server>.
This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.
Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

(as I said, lamd is running as "lampi" on all the hosts).
what are we doing wrong?
Thanks.
Sam.
