[CSBi-HPC] IBM cluster firewall upgrade

[Al Davis]

We need to upgrade the OS on the firewall system for the Whitehead half of the 
IBM cluster.  As there hasn't been much activity so far this year, we purpose to 
do it on Thursday or Friday of this week.  Let me know asap if either of those 
days will cause a severe problem for any computations that you had planned.

The firewall should only be down for several hours, but plan on it be 
unavailable for the whole day.  Note:  This won't affect any jobs that are 
currently running on the cluster as only the firewall will be impacted.

We plan on upgrading the software on the cluster nodes over the next couple of 
months and will coordinate this with everyone.  We'll upgrade a few nodes at a 
time so you can test your software on them to verify everything still works as 
before.  This should provide us with a more stable system and better batch 
scheduling software - yeah.

thanks, al
