Serpentine (Nov 10 2008)

Reminder: Tuesday (tomorrow) is a national holiday. We'll be having our weekly outage on Wednesday.

It's been a bit of a rocky weekend. A rocky week, actually - since the last regular Tuesday outage the CPU load on anakin (the scheduling server) has been kinda high. Like around 100. The obvious answer - turning on client logging for debugging on Tuesday - wasn't so obvious at first as we thought we vindicated that and moved on to finding other possible problems which were all red herrings. Eventually we were brought back to client logging and Dave made an optimization fix which we tested in beta this morning, and Jeff applied to the public project around noon. This brought the load back down to 1. I guess the fix worked.

Our raw data pipeline management still needs work. Lots of bottlenecks make it impossible to keep a steady, automatic flow of work. In a perfect world it would be simple and serial - data drives sent up here, files brought online and acted upon by both multibeam and astropulse splitters, copied down to archival off-site storage, and then deleted. However each step takes a rather long time (hours per file if not days), and storage is limited, so we have to parallelize as much as possible. One possible effect of this, and one we're seeing now, is that we currently don't have raw data available for astropulse to split. We're loathe to copy data back up from the archives unless we really have to. We still might do so, but we are expecting a new shipment of drives directly from Arecibo today or Wednesday so astropulse at least be will be fed then.

The bright side is this is now very clear on the server status page now that I made some updates to finally split out database counts/rates and splitter activity per application. There's still more updates to be done, but now it's much easier to tell what's going on between the two.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...
