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. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Speaking of beta, are you going to turn the task deletion back on? I have some 500 going back to april showing up. Thanks for the good work. Gary Some small improvements today during the outage.

Task deletion has never been ON, at the beta site. And keeping them un-deleted shows how much optimisation has been achieved from first version until release here on main site. |
