End of the week wrapup. I'm still working on the workunit table cleanup, but we're in the paranoid-testing-before-we-drop-the-old-table phase. So far, so good.

As for Astropulse, the splitters are off, and will remain off for at least the weekend, for a couple reasons. First, we made some global changes to the science database schema, and thus the db library code, which affect both multibeam and Astropulse. So we still need to recompile the Astropulse splitter to accommodate these changes (and it cannot be run until we do). Second, from what I understand we are close to releasing another Astropulse client, which will also require some splitter-related tweaking. Both these things are waiting on Eric, and he's out of the lab until Monday.

However, somewhat conveniently, we had a RAID drive fail on the Astropulse database server this week, so it's been quite nice and easy to replace this drive and rebuild the RAID while everything is quiescent. So there's that silver lining.

In case nobody noticed I had to mess around with jocelyn (the mysql replica server) today. It's root filesystem filled up as the qlogic card started cluttering the logs with dozens of useless messages a second. I upgraded several packages and the kernel and rebooted the system and that seems to have calmed it down.

The two new servers (paid for by donations to the GPU User's Group) have been assembled and soon to be en route. We'll start playing with those hopefully by early next week! These will really go a long way towards improving the performance per rack unit of our server closet!

And to echo what I already posted on the front page: The entire lab is undergoing some electrical power tests on the morning of Monday, March 5th. All SETI web sites and servers will be unreachable for 2 hours (from 8am to 10am, Pacific Time).

Astropulse 6.01 released for linux i686 and x86_64
This is mainly to finally get the outlier detection working for the BOINC credit determination scheme. Windows version will either be out in the next 24 hours or a week from now.28 Feb 2012 | 1:49:59 UTC

I'm waiting for an official AP app for OSX. Any clue if that is coming anytime soon?

Speaking of power issues - did anyone ever find any smoking guns causing the power fluctuations that plagued the project, hrm, a year or more ago? Is this test aimed at resolving an issue you found and then isolated and kept the servers away from?

Thanks Matt, your updates are always welcome.
All the best for the power outage on Monday, and that Murphy slumbers long and deep that day.

Thank you, Matt. The kitties luv your news posts!!!
Get them servers offline Monday before the power surges!

Hoping you have a little bit of fun, aside from the chores, when getting the new servers online.

Meow.

Hi, Matt -- Since the AP servers are off, the SETI system is running so smoothly without the internet link congestion. What ever happened to the possibility of joining the gigabit link that the rest of the lab has? It would be utopia!

Thanks. Whit
