Message 958143 - Posted: 23 Dec 2009, 0:30:10 UTC

Oy! So the day ended yesterday with some good and bad news. The good news was that the air conditioning problems we were having were not due to our a/c unit, but due to the whole building turning off some circulation fans in order to save money over the holidays. Apparently these fans have been helping us out a lot. So we got them to turn those fans back on again until we figure out a better situation in the new year. At least they said they'd turn them back on again...

The bad news was that we discovered that spikes and gaussians were failing to be inserted into the science database by the assimilators. These were actually two separate problems that pretty much ate up our entire day today trying to figure out. The spike table simply needed more space. The gaussian table errors were terribly misleading, and we barked up several trees before determining there was some corruption in one of the indexes. We dropped a couple of the less crucial indexes until we were able to insert gaussians again. Jeez.

Other than that... we're ramping down our presence here at the lab now that the holidays and forced furloughs are upon us, but we'll of course be popping in from time to time anyway (remotely or directly) to deal with various chores, including this massive power outage on Sunday/Monday.

Happy remainder of the year!

Hey, so the Technical News page has been broken for over a week now ("Database Error"). Can someone fix that? It's at http://setiathome.berkeley.edu/tech_news.php , and linked from the home page as "Technical News".

Chris, I believe the reason is that it was moved to here: http://setiathome.berkeley.edu/forum_forum.php?id=908

Open up a window? ;-)

Happy holidays to you and the rest of the crew!
Hopefully you have a silent Christmas, without needing to rush over when things go down.

If they had windows then they would know when it's day/night & might stop working. :D

Have a good holiday there & stay out of the office! :P

Until then, Merry Christmas and all that jazz. :)

Will the http://boinc.berkeley.edu/ servers also be affected by the power outage? I seem to remember that those servers used to be co-located with S@h servers.

I checked the BOINC front page, there is no warning there of a power outage at the moment.

Hope everything goes down and back up smoothly.

Keith

[edit]
Also I assume that http://setiweb.ssl.berkeley.edu/beta/ SETI Beta will also be down as well. No warning on that site either, although it will affect a lot less people than BOINC servers going down, which is linked from every BOINC project.[/edit]

If you crunch more than one project, and the other project(s) are up, it won't affect you at all.

If you have enough work in your cache, it will be a non-event.

If you're brand new to volunteer computing, and you want to download BOINC, that will be more of an issue.

I think so, since it lives in the same building as the Seti project. Not sure if it's in the same server cabinet, but since the power outage for the major power upgrade will affect several buildings, it doesn't really matter where in the building the server is.

Matt, something is broken..

Results before and after the outage go in 'validate error's.
