I'll start with hardware - just some minor things. First: the boinc.berkeley.edu website (and alpha projects) were down for a while this morning because the BOINC server froze. Still not sure why, but a power cycle cleared that up. Second: currently AstroPulse scientific data only exists in the "beta" realm - Bob and company are now creating the db spaces on the master science database server along with SETI@home. This may slow things down temporarily due to heavy disk I/O. Third: we got our second new enclosure (the previous one was broken) so we're starting to archive data off site again via our ISP, hence the slightly noticeable bump on our traffic graphs. I guess from this point on you shouldn't assume all transferred bits depicted on said graphs are due to workunit/result exchange.

Software wise, we're chugging along on the various projects mentioned in previous threads. When we all get into programming mode this generally tends to uncover bugs/issues that went unnoticed during network manager mode (or scientist mode, or administrator mode, or ...). Things like being able to insert workunit_groups of any size, but only able to read ones under 8K. Not a problem when all we're doing is inserting, but now that we have to read them back in to do some precess adjustments, this constraint uncovered a few such groups that were extra-large in size. Why? Well, that's what I mean - one little headscratcher leads to another. I've been on this all day, and Jeff's been beating his head on this "ragged file" problem causing some splitters to error out - but when we restart them on the same files they work. Why? Why?! Actually, these problems are kinda fun as when we do discover the root cause there's a happy "a-HA!" moment.

Thanks for the info Matt......was wondering what that uptick in network traffic was all about......
