Modules

  • Versions
$ module avail namd
------------------------------- /opt/soft/modulefiles -------------------------------
namd/2.6.2009-02-11-Linux-x86_64-MPI-icc-1(default)
namd/2.7b1-MPI-icc-1
Version 2.6 is the CVS development version, and NAMD 2.7b1 the subsequently released official version.
  • Add the following to the end of your ~/.bashrc file:
module switch openmpi openmpi/1.3-intel10-4
module load namd
and also issue it on the command line (or simply re-login). The program will be available under the name namd2.
  • Verify availability
$ type -p namd2
/opt/soft/namd-2.6.2009-02-11-Linux-x86_64-MPI-icc-1/bin/namd2
Note: This step is solely meant to verify that the binary is reachable simply by its name. As with other applications, do not call it directly, as the paths are version dependent. Use the module command to select appropriate versions.
