Installation Instructions

To compile GM on VxWorks platforms, you will need to follow the detailed installation instructions in the README-vxworks file in the GM distribution. Specifics about GM can be found in the file README. Unresolved questions may also be addressed in the FAQ.

Current cautions and common problems:

  • GM-1 does not support the new M3-CLOS and M3-SPINE Myrinet-2000 switches.
  • Do not use the configure flag --enable-directcopy with GM 1.5.2.4. This flag is not a valid option to GM 1.5.2.4. It will be re-enabled in a future release.
  • If the host is rebooted, you must reload the GM driver and rerun the GM Mapper.
  • The GM Mapper must be run before any communication over Myrinet can occur.
  • In most cases, the GM Mapper should not be run continuously. It is intrusive and can interfere with network traffic intensive jobs (e.g, MPI applications).
