The good news is that recent woes due to lack of workunit disk space have seemingly passed for now. We're still on the very edge of our capacity, but now that we're prioritizing the smaller regular workunits (as opposed to the big Astropulse workunits) we were able to build up a ready-to-send queue and network traffic stabilized overnight. The less-good news is that we still need to build some indexes on the science database. We're building one now, and it usually takes 12-24 hours. This adds a lot of CPU and disk I/O to the science database server, meaning the splitters can add rows as fast, nor can the assimilators. So the ready-to-send queue drops, and the assimilator queue rises. As an added bonus, when the assimilator queue rises, that means the deleters slow down, which means the available workunit disk space reduces, and we're back to square one again. No big deal as long as people are patient. All the backend services are doing the best they can until the index build finishes, and then we should catch up again. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Thanks for all your hard work to keep things going... And this explains why the RTS queue is now empty, and the cricket graphs have gone down... Mark |

Matt--thanks for the updates! I'll give you a call next week about hardware donations |

Thanks for the advance notice. Knew you were running on the edge, just didn't realize it was that close. Gary |

Matt--thanks for the updates! I'll give you a call next week about hardware donations @ Matt, Is there anything we can do to increase storage (like get some more/bigger drives) or is the server simply not able to plug any more drives (or cope with larger ones)? @ Blurf, Perhaps a limited time donation drive for this specific purpose (assuming more/bigger drives are useful)? Cheers, MarkJ BOINC blog |
