MPICH Simple Launcher

This is a simple socket based launcher used to start mpich applications. It is not secure and it does not impersonate the client user when launching processes. It does not require special privileges to be installed. The reason this launcher is provided is so that users who want to evaluate the software can install an run mpich applications easily, without requiring administrator privileges to install.

There are two parts to the launcher:

1. MPICHSH.exe
2. MPIRun.exe

MPICHSH.exe is the server which resides on each host in the cluster.

MPIRun.exe is the application launcher which connects to the servers and launches the mpich application.

Note: The MPICH runtime dlls must be installed on each node before an MPICH application can be launched.
