Happy new year! Actually, being that every moment is the beginning of some arbitrarily defined era, I should be more clear: Happy new calendar year number 2008, whoever uses this particular calendar system which I usually do!
The weekend was busy with the more-and-more-common fast workunits. Discussions today at the lab brought up the fact that about a third of our data will translate into these fast runners, so we better turn our attention back towards improving the data pipeline. We picked two low hanging fruits today: convert server bane from a redundant web server to a secondary download server. This will help determine if that bottleneck is the server or the storage. I also added a flag to the splitter scripts to select files in beam/polarization pair order, not filename order. This will help pseudo-randomize the creation of work, and hopefully spread the pain of fast workunit periods so we aren't so overwhelmed at times.
Nevertheless, we have Astropulse coming down the pike, and have a lot of SETI@home data to go through (and we're starting to collect new data again!). So we need to upgrade the network/servers in a big way. And acquire more participants. Not sure how this will all happen yet, but it has to happen.
Meanwhile, we might try another science database index build tomorrow (or soon thereafter). Bob found a way to do so while the database is up and inserting rows, so we might not have to shut down splitters/assimilators during the long build. Cool.
