Page 54: Setting Environment Variables In System-Wide Startup Files
Editing Environment Variables Setting Environment Variables in System-Wide Startup Files This method is used to set a system-wide default for which MPI implementation is used. This method is the easiest for end users; users who log in automatically have MPI implementations set up for them without executing any special commands to find MPI executables, such as mpirun or mpicc. -
Page 55: Editing Environment Variables Manually
Chapter 7 MVAPICH MPI Editing Environment Variables Manually Typically, you edit environment variables manually when it is necessary to run temporarily with a given MPI implementation. For example, when it is not desirable to change the default MPI implementation, you can edit the environment variables manually and set MVAPICH to be used for the shell where the variables are set. -
