I think measuring a clusters success based on the number of jobs run
or cpu's used is a bad measure of true success. I would be more
inclined to consider a cluster a success by speaking with the people
who use it and find out not only whether they can use it effectively

What's the typical protocol about the cleanup of /tmp folders? Do
we just leave the default (2 week) cron-driven tmpwatch in place.
we don't have a lot of users who bother with /tmp, though, since
we have reasonable lustre-based storage on all our big clusters.

Redhat and the likes have a utility called 'tmpwatch'

The measure of a cluster depends on how it is intended to be used.
Big computer centers tend to measure the percentage of time the CPUs
are running jobs. In contrast, if a cluster is used for program develop
there must be idle CPUs in order to reduce that wait time, keeping in
mind when people wa

I couldn't have said it better myself. Be wary of suits asking for
asking for numbers.

What sort of business management level metrics do people measure on
clusters? Upper management is asking for us to define and provide
some sort of "numbers" which can be used to gage the success of our
cluster project.
We currently have both SGE and Torque/Moab in use and need to measure
both if
