Feel free to send these types of questions to [email protected].

If GM_INSTALL fails with unresolved symbols such as the _Rsmp
suffix, then this signals that there is a mismatch between
the running kernel and the source kernel tree in your 2.4.19
installation.  Details can be found in (5.) in the following
FAQ entry:

  http://www.myri.com/scs/faq/faq-install.html#install6b

The GM_INSTALL script performs the following operations:

   * Shuts down existing IP over Myrinet
   * Unloads existing GM module (if it exists)
   * Creates the devices (/dev/gm0-4 and /dev/gmp0-4)
   * Loads the GM module (insmod)

Feel free to contact us if you have further questions.
