[mpich-discuss] Execute in two machine

[Jayesh Krishna]

Hi,
 The "-machinefile" option allows specifying a machine file (you can create a text file using notepad containing the ipaddresses of each node in a separate line) containing the information about nodes where your MPI processes would be launched.
 You have two options with respect to your executable,

1. Copy the executable to the same location (e.g. "c:\mpitest") on all the nodes
OR
2. Share the directory containing the executable and use the "-map" option of mpiexec so that each process can map the shared drive.

 As mentioned before "Windows developers guide" contains a lot of information related to your questions.

Regards,
Jayesh

Hi. I have set all the nodes with the same windows username and
password. But, I still confuse how to use commang "-machinefile"
Whether each node must have the executable file? Or simply just on one
node and then shared to all nodes?
Thanks

I would recommend using the "-machinefile" option (see the Windows developers guide for details - http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs) to specify the list of hosts to execute your job.
