IU is setup and running on our Odin cluster.

Nightly we run 8 nodes (16 procs):

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

It seems that the DB 'cleans' itself every so often. Meaning that I

page. Is this true? How often does it do this?

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