The AC work is complete, it will probably take me longer to power the
systems back up than it took to replace whatever belts and rollers
needed replacing....

In future we know we can roll through this amount of Air Conditioner
downtime, sorry for the disruption.

- Matlab licenses unavailable this weekend:

The Whitehead server that provides Matlab licenses to the NE47 half of the 
cluster, will be down for the entire weekend and thus you won't be able to get a 
license.  If you've precompiled your Matlab code it should run without a problem.


- Running the correct Matlab version:

Some people are still using the old version of Matlab and the expired licenses 
on this half of the cluster.  I've moved the new Matlab installation and license 
file to a common directory that is pointed to by the environmental variable: 
MATLAB and have included the new executable directory in your default PATH. 
These variables are defined automatically for you when you login.  To make sure 
they're also included in your loadleveler jobs you can add the following command:

environment = MATLAB; PATH;

or to get all the environmental variables use:

environment = COPY_ALL;

I'll soon remove the old version of Matlab from the system.


- Running Matlab without java and a terminal display:

To run Matlab, you should just use the command:

matlab -nojvm -nodisplay

The nojvm & nodisplay options startup Matlab in command mode without any graphics.
