[Beowulf] Performance metrics & reporting

We report similar metrics, but do so in a very project oriented manner.
We have fairly strict project allocation guidelines that dictate
accurate system accounting.  Depending on which batch system you're
going to use, this can be fairly easy data to collect.  

The PBS accounting records are not terribly easy to read.  Our
accounting scripts utilize a simple state machine to pull the necessary
data.  GridEngine accounting records are very easy to grab data from.
Simple colon delimited format, one job per line.  Sun also released the
ARCo accounting tool.  [They released it open source immediately
following me completing development on just such a tool....]  It will
allow you to poll useful information out of the accounting records w/o
doing a bunch of scripting.  I believe Altair is working on releasing a
similar product for PBSPro [but not free].  

At any rate... hope this helps :-)
