Running MPI on the algol and qstruct clusters In order to run MPI, the MPI runtime needs to know about what machines you will be running on, and to ensure that you have permission to run on these. The following is what I did in tcsh -- you may need to use slightly different commands to set your environment variables in different shells. These commands should only need to be done once: 1. create a file .mpd.conf in your home directory and change its permission to only be readable by the owner, i.e. [[email protected] ~/TEST]$ chmod 600 .mpd.conf It should contain the line: MPD_SECRETWORD=xxxxxx The xxxxs should be replaced with a random string of letters and numbers -- this word lets MPI keep your processes separate from other's processes. DO NOT PUT YOUR PASSWORD IN HERE! 2. Create a file with the node names you want to use. Call this file mpd.hosts, and put it somewhere you can remember, like your home directory or the directory you run programs from.
