Dear William,
This is the essential line you need to focus on:
> rsh: host.utoronto.ca: not found
It is telling you that host.utoronto.ca cannot be found. The problem is
thus with your mpi configuration. You need to check the mpi machine
definition file for your system.
- Does it list the correct machine names and number of processors.
Try typing "uname" to get the correct hostname for your machine and
correct the mpi definition file as necessary.
You will also need to add this host and all other hosts you want to run
the mpi job over to .rhosts in your home directory in order to allow rsh
to these machines without a password.
Without more detailed information on your system set up and mpi
configuration it is a little hard to offer a detailed solution.
All the best
Ross
