[auton-users] CPU Upgrades and Request from Sysadmin: PLEASE RESPOND

[Michael J. Baysek]

Hi Lab,


I have great news.  We are going to be upgrading our computing machines 
to much faster processors.  We have tested this upgrade on LOR2, and we 
saw a test run of AFDL go from taking 12 hours to 7 hours. 


In order to make sure each machine is built with the proper revision of 
hardware, I am going to need to power down and remove each and every 
LOP, LOQ, and LOR machine from the rack for a few moments so I can 
visibly inspect the system boards.  Any processes that are running will 
need to be stopped or administratively killed before I can proceed.


If you are a current active user of the lab, please get back to me by 
WEDNESDAY if you have (or plan to have) any crucial processes running 
anywhere on LOP/LOQ/LORS for the upcoming weeks.  Please specify your 
time frame start and end, if you expect to have any processes running 
for > 24 hours.


I prefer to do this check on a weekend, and all in one shot if possible, 
which basically means a couple of hours of complete downtime for the 
machines in question. 


Thanks.  Please try to respond by Wednesday, so I can formulate the plans.


Best,

--
