Mac Knifed (Jul 22 2008)

Message 785481 - Posted 22 Jul 2008 21:16:02 UTC
Yesterday afternoon we installed in a new scheduler which included some updates necessary for the upcoming Astropulse rollout. However, our network performance took an immediate hit. After about 10 minutes trying to figure out what was causing this Jeff and I realized our scheduler switch perfectly coincided with several expensive credit-analysis queries Eric was running, also in regards to the Astropulse rollout. So it wasn't the scheduler - just the database getting overloaded. That got cleared up quickly.

Last night I noticed people complaining about Mac computers being denied work. This is still an issue, probably with the new scheduler implementation, and we'll address it shortly.

We had the regular weekly outage today during which I tackled some extra things. First off, due to continuing mysql database performance issues we completely dropped the credited_job table (before we just dropped the indexes). Reminder: this is the table that connects user ids in the mysql database to result ids in the science database, so we know who did what. This is also the only table in the mysql database that grows without bounds, and therefore has been the cause of much headaches as of late. Don't worry - we have all this data archives in three formats in three different locations, and will continue to collect this data in flat file format. I also checked the integrity of the database filesystem now that it was cleaner. No problems there. I started up the projects and mysql is currently handling well over 2000 queries/sec without breaking a sweat.

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...

Thanks for the stats, RD. :beer:

Sure hope our MAC crunchers don't run out of work before the problem is fixed.
