IU is setup and running on our Odin cluster.

Nightly we run 8 nodes (16 procs):
   trunk,v1.2 (gcc)
   IBM,Trivial,Intel,IMB
   Currently just using tcp,self (due to some cluster mgmt issues)

Weekly we run 32 nodes (64 procs):
   Same configuration as the nightly

We are still doing some local debugging (not MTT issues really, just
cluster stuff) so commits to the MTT DB may come a bit more
frequently now then they would normally.

We may have some other clusters coming online in the future, but we
can't give specifics at the moment.

I have been putting any bugs I see into Trac as they popup (sorry for
duplicates).

It seems that the DB 'cleans' itself every so often. Meaning that I
notice that runs from a week or so ago are no longer in the summary
page. Is this true? How often does it do this?

Cheers for all the hard work. This is looking really nice and useful.
