RE: [myrinet] how to build a module of gm for use during linux boot/setupprocedure

This is what I do for RH 6.2.

0.  Build your kernel, then build GM, verify that GM works (run GM_INSTALL).

1.  Type:

for i in 0 1 2 3 4 5 6 7
do
	/bin/rm -f /dev/gm$i /dev/gmp$i
	/bin/mknod /dev/gm$i c 41 `expr $i "*" 2`
	chmod a+rw /dev/gm$i
	/bin/mknod /dev/gmp$i c 41 `expr $i "*" 2 + 1`
	chmod a+rw /dev/gmp$i
done

or

just run GM_INSTALL once to create

or

have your network installer do it.

2.  cp sbin/gm to /lib/modules/{kernel version}/net (no need to append .o,
just leave it as gm)

3.  Add to /etc/conf.modules:

alias myri0 gm

4.  Type depmod -a

5.  Create a ifcfg-myri0 entry in /etc/sysconfig/network-scripts (use
ifcfg-eth0 as an example).  Even if you don't need IP for your Myrinet, give
it an IP anyway, someone always asks for it.  E.g. NFS.

6.  Reboot and enjoy.

NOTE: if you plan on using NFS or any other IP-based service on start up,
mapper must be running somewhere.  If you want the active mapper node to
also boot this way, you need to create a mapper service in /etc/rc.d/init.d
that starts before network starts.  Your mapper service will have to load gm
first.  Static maps may be a good idea, but I have not tried it yet.  Ping
me next month to see if I have.
