Zombies (Oct 29 2007)

There were minor minor hiccups over the weekend, mostly due to a concentrated bunch of noisy workunits being pushed through the pipeline. Other than that - no big server issues to mention.

Some people discovered a single BOINC client creating new, redundant hosts at the rate of one every few seconds. In the grand scheme of things this is no big deal. Bob usually checks for such things every so often and removes the zombie hosts to keep our hosts database as trim as possible. This case was slightly unusual due to the creation rate. I contacted the participant in question and we confirmed an old client on a system running Vista was to blame.

Brain Transplant (Oct 30 2007)

Some small improvements today during the outage. First, just to get the ball rolling in some positive direction, we moved ptolemy (the redundant scheduling server, among other things) out of our secondary lab and into the actual closet. This was an easy procedure, except it wouldn't boot up after the move. After successive reboots, but before utter panic set in, I guessed it was a hardware RAID configuration problem - I pulled out all the superfluous non-boot drives and then it booted up just fine. Phew.

Second, we pretty much given up on bane which meant its parts were free to cannibalize. So I upgraded the memory sidious (MySQL replica server) - it was at 16GB, now it's at 24GB. Sidious has been having more and more trouble keeping up with the master database on jocelyn as of late. Perhaps this will help.

Jeff is compiling a new multibeam splitter with additional smarts to account for a new radar blanking signal in the actual data (to help keep radar noise out of the workunits before they are split). We'll test this in beta first - which as it happens ran out of work last night. So workunits generated by this new splitter should be in beta any second now, and then soon in the public project.

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
