Hi,

I saw your posting on the Myrinet mailing list.  Feel free to send questions
to [email protected] if you have difficulties.  We'd be happy to help you.

gm-1.4 does not work with Linux 2.4.

We're in the process of final testing for gm-1.5, we highly suggest that
you download:

ftp://[email protected]/pub/GM/gm-1.5pre4.tar.gz

and if you're using MPI, there is also a new release of MPICH-GM,
that will be posted to the webpage as soon as gm-1.5 is released.
This version of mpich-gm requires gm-1.5preX.

ftp://[email protected]/pub/MPICH-GM/mpich-1.2.1..7.tar.gz

The official gm-1.5 release should occur sometime in the next week.

Hope this helps.
Susan
