Message 1072869 - Posted: 31 Jan 2011, 23:44:06 UTC

Tomorrow during the usual weekly outage we're planning to make the switch from "synergy" bruno back to the "real" bruno. The synergy substitute has performed wonderfully, though it did reboot itself yesterday (not exactly sure why but I think a runaway process clobbered the system). This was why the uploads weren't working between yesterday afternoon and this morning. Speaking of outage tasks, I also hope to start converting thumper into a non-database server tomorrow. Going to be a pretty busy day I guess.

Today I've been during the usual post-weekend cleanup and some analysis stuff. I'm doing a timing test right now on oscar doing some of the hefty reads necessary to generate all the plots for public consumption. On thumper these were taking 50 minutes per a specific time-wise chunk of spikes. Now it's more like 35 minutes per chunk. So that's good, and we haven't even fragmented this table/index yet, and still have plenty RAM to use for buffer space. Slow, steady progress.

Oh yeah, heads up: There's going to be a lab-wide network outage out of our control Wednesday morning (Pacific time) around 5:30am until 7am. This may not affect the Hurricane traffic, so you might not notice except for not being able to reach this web site, and event then we might be down much less than 90 minutes.

Thanks for the update and the heads up Matt. You got things fixed just in time this morning, I was crunching my last GPU WU. Best of luck on all you have to do tomorrow.

Matt, thanks for the news!


My 940 BE with 4x GTX260 OC is still ULing. Still ~ 500 results. But not longer backlog.
I love my DSL light with 8 KB/s UL speed.

Excellent news - we all were wondering what happened with the uploads not working and still seeing a green light on the server status page.

I never could wrap my head around all that DBA stuff. Hats off to you and your expertise Matt. I know you don't like to take all the credit, but you do an amazing job keeping things going and tweaking the systems for optimum performance. I don't think I could ever do what you do, and I'm thoroughly impressed with what you write here (even if some of it is in brevity).

A yay for synergy and a big woohoo for bruno's return. Don't know much about the plots but I'm sure they'll look pretty :)

Would those plots have something to do with the "Signals already found" section of the "Science status" page? (which hasn't worked since before the October outage...)
