Dear members of gridengine,
I have problems running mpi jobs with SGE. The error message is:
"unable to find pe_start file
"/softw".
Unfortunately not the whole path is printed so I can just guess.
I created with qmon --> Parallel Environment Configuration the Environment: "mpi"
-->
Start Proc Args: /software/sge/mpi/startmpi.sh -catch_rsh $pe_hostfile
Stop Proc Args: /software/sge/mpi/stopmpi.sh
which MPI implementation do you intend to use? With Open MPI and MPICH2 you get
a Tight Integration nowadays without and special procedures.
I guess the tight integration without special procedures means I don't
need to determine "Start proc Args" and "Stop Proc Args" in the Parallel
Environment Configuration. I just did gave them the value "none" and now
the jobs are executed. Thanks.
But I have another problem: the mpi communication should go over the
infiniband-network and not over the management network (at the moment it
does the last one). To do so should I change the names in the /etc/hosts
file (the hostnames and the management interfaces have the same names,
and SGE selects hostnames not interfaces)? Or is there another possibility?
Ursula
