Things went mostly well in server land. The astropulse validator was (still) choking on various results so the backlog grew and thus the workunit storage filled up again for a minute there. That means the splitters halted, and we ran low on work to send out for half a day. Other than that, no major events. Today we began the final stages of the secondary science database shuffle. We were a bit disappointed by the results at first, and did some more reconfiguration/testing before learning to not trust the output of iostat so much as the other evidence that shows we may have improved our peak science db throughput by 10x. Well maybe not so much - we'll see - if it's 2x I'll be psyched. More work tomorrow on that (the secondary is still catching up from being offline for 5+ days). A followup on a recent story about our Overland Storage servers. I recently mentioned we hit an unexpected 4 TB file system limit on our workunit storage server (gowron). Turns out we actually hit a physical extent limit, and this will be fixed in the latest OS release. This is really just an academic point - we could only grow to 4.25 TB max anyway, given the number of drives. Thanks again to Overland for continued support. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Could you pass it on to the CUDA committee, please? ID: 855987 ·
