Technical news, and SETI@home daily stats for 26.04.2007.

[Rattledagger]

Yesterday afternoon I mapped out a bunch of ethernet cables in the closet. Still stumped by stymied splitters I went ahead and started moving all the BOINC backend servers to the new gigabit switch. Right off the bat there were no obvious gains by doing this, except for the much nicer monitoring tools. This is not to say the switch is useless - the problem is we are currently running mostly on servers that can't speak faster than 100 Mbit. This will vastly change once bruno/sidious/et al. are brought into the closet. Jeff and I re-routed some of those cables this afternoon - cleaning up some of the spaghetti.

Back to the splitters: I pretty much determined the bottleneck is strictly CPU. Some tests this afternoon (which caused even less work to be created/distributed) more or less proved this. We can only run splitters under solaris and those machines are almost tapped out. Jeff is close to compiling the splitters under linux, and then more servers can come to our rescue. We'll get you more work, I promise.

Bob fixed the replica problems I was having last night. Simple configuration stuff. Now I know so I could fix the problem myself next time. But then it failed when trying to sync up from the vast master backlog. Turns out one of my donation-processing scripts was still writing to the replica, so this caused it to barf on updates from master with duplicate IDs. Luckily I was able to track this down and clean it up rather easily, so the replica is back on line and probably caught up by the time you read this sentence. Or maybe this sentence.

By the way, after the outage yesterday I purposefully didn't restart the web server on kryten, so bruno is now officially the only upload/download server. Kryten was still getting a few hits here and there, but enough is enough already.

Some pesky search engine robots (from livebot) were causing our web servers to slow to a crawl - a link to our cvsweb.cgi utility sent them into a frenzy. I firewalled them (for now) and updated my robots.txt.
