[Research] Compute Machine Upgrade Complete

[Michael J. Baysek]

Hi Everyone,

All of the compute machines with the exception of LOKI (Alpha 
Archictecture) have been upgraded to CentOS 4.  *For most uses, you will 
not even know it is a different system.*

Some things to know working on the new installation:

1)  It is possible that you may need to recompile your binaries.  Keep 
this in mind if your programs misbehave.

2)  CCache is enabled systemwide by default.  This will speed 
recompilation of your programs.  To learn more about CCache, and how to 
use it to your advantage, visit 
http://www.autonlab.org/auton_intranet/docs/ccache.html

3)  During the upgrade process, a few ssh keys were lost.  You will 
receive a message stating that "REMOTE HOST IDENTIFICATION CHANGE" when 
you connect to LOQ1, LOR1, LOS1, or LINA.  Simply open up your 
~/.ssh/known_hosts file and remove all lines containing those machines, 
and this will allow you to connect.

If you have any questions or feedback, please let me know!

-Mike
