I'm running on about 170 SUN Ultrasparc 1 Solaris machines, and 10 SGI
machines. I wrote scripts to monitor other users' activity so as not to
interfere. During the day (8am-midnight) a console login kills any
process using more than 5 minutes CPU time. After midnight, or if no one
is on the console, I check to see if any one else is logged on and
working. If there is, I kill -STOP the dechall client. If everyone has
been idle for 10 minutes or more, I kill -CONT the client. I also stop it
if the load gets above 1.2, waiting until it drops below 0.1 before

Last week a lot of student were working on year end projects, so only
about 20 sparcs were running deschall at any given time during the day.
We're now up to 50-80 at most points during the day.

A grad student friend of mine is running it on their lab of half a dozen
Ultrasparcs. A few students are running it on their PCs, but not many.
I've given up getting more support for now. Most students leave after
this week. Perhaps during next week I'll look into getting deschall
running in the PC and Mac labs, if they aren't being used much. I go home
on the 19th. :(
