Step 2 of 7: Getting Started

The first step in using MPI is to create a MPI directory under your root directory. To do this, execute the 'mkdir' command in a command tool:

% mkdir MPI

Second, you must have a file called .rhosts. This file will allow connections from the specified machines by the specified user names. This will allow MPI to start a process on the specified machine. An example of the .rhosts file is given below. This file should be stored in your home directory.

#
# .rhosts -- File allowing remote connections
#             from specified machine and user
#
# The second argument must be your user name.

Once you have the .rhosts file, you need to execute the following commands at a command tool prompt from inside your home directory:

% chmod 600 .rhosts
% fs setacl . system:anyuser rl
% fs setacl ~/MPI system:anyuser rl
