So synergy is currently acting as a maul replacement. In fact, I turned off maul to keep the temperatures down in our secondary lab where these and other servers are currently located. I've been running all kinds of other tests on synergy that I've been up[ until recently running on vader. In short, we're burning it in.

We continue to work on the disk i/o issues on oscar. When we do these weekly database backups it really gums up the works. Some of you have noticed the assimilators falling behind, etc. Actually Jeff stopped the aforementioned science analysis programs to allow the database to finish up its current extra load. It's also running a weekly "update stats" on various tables. I'm still hopeful we have a solution without our current means that we have yet to try (give more memory to informix, db or raid configuration tweaking, fragmenting the indexes, etc.).

Meanwhile, I'm back to work mostly on some actual science/visualisation stuff.

So, what are you guys going to do when you actually have to get back to work instead of babysitting servers all day? :-)

I hope all three of these new computers live up to or exceed all expectations. You and all of us deserve some great uninterrupted time to get something done.

Thanks for the updates and hard work. Once this I/O issue gets sorted out on Oscar, are there any plans to extend the validated result purge cut-off to at least 12 hours? It's not a show-stopper, but for myself (and presumably others who are actively involved in beta testing the optimized apps) it's just a little bit inconvenient.

Personally I would prefer 24 hours as before. I'm not on 24/7 and there can easily go 12 hours before I can check tasks.

Read Matt's latest post.....
He says it's now back to at least 24 hours.

Just did 10 secs ago :) Great!
