Remote Shell Server

The remote shell server is a DCOM server which resides on each host that provides CPU's for mpich applications. The DCOM server runs as a service under the SYSTEM account. When MPIRun connects to the remote shell server, the server impersonates the user who executed MPIRun and launches processes in the context of that user. The server does not map the network drives that the current user has mapped. The server does not load the registry hive of the current user.

With the server installed on all the machines in a cluster, you can use MPIRun to launch an mpich application:

You must install the MPICH runtime dlls before attempting to launch an application with MPIRun.

MPIRun

MPIRun has an option, -np, which runs an application on the first n available machines. To set up the -np option for MPIRun, run MPIConfig:
