1.2.4 Directory Structure
All HP-MPI (for Linux) files are stored in the /opt/hpmpi directory. Table 1-3 describes
the directory structure.
If you choose to move the HP-MPI installation directory from its default location in
/opt/hpmpi, set the MPI_ROOT environment variable to point to the new location.
