<P><FONT SIZE=2> Hi,<BR>
Once you have MPICH2 installed on a windows machine, the process manager is already installed/running on the machine (No specific configurations required). The firewall may block connections to the machine, so make sure firewall is turned off (or use appropriate rules as mentioned in the windows developer's guide - <A HREF="http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs">http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs</A>) on the machines.<BR>
You can use a machinefile to provide information on the nodes used to launch your MPI job. In your case you can create a machinefile, say mf.txt, containing the text "G-server:8" and launch your job using the "-machinefile" option of mpiexec (mpiexec -machinefile mf.txt -n 8 cpi.exe).<BR>
Let us know if you need further assistance.<BR>
