Well, like I mentioned yesterday I'm working on more scientific programming than network administration these days (for a refreshing change). Actually plotted out some recent data this morning for the gang which pointed out a bug in our splitter - apparently we haven't been notching out as much garbage data as we should have. Eric/Jeff are fixing that now. That should eventually mean less overflow workunits wasting everybody's time.

Jeff and Bob and also quite busy working on the science database replica stuff. It's been a real bear getting Informix up and running on the replica machine, due to all kinds of version, configuration, and permissions issues. But as I overhear their discussions it sounds like slow but positive progress is being made.

The outage recovery yesterday was pretty quick. Seems like recent web tuning and workunit file distribution over several servers has been working perhaps? Eric is managing the transfer of date from one NAS to two until it's a 75/25 split. Currently it's about 80/20.

Thank for the update, Matt. And keep up the good work.

Matt!
I have a qustion about the pending credit.
What's doing it? I'm sure you have mention in before, but I also though you already fix the problem. Or is the reason something new?
And why does it take so long time to get back to zero pending again?

Nice Work there Matt - Congratulations to All of You @ Berkeley . . .

Pending credit will rarely if ever be 0. You will almost always have something waiting for the other host to finish up.

Even more so with the long deadlines on these Work Units and the initial replication & distribution of only 2.

Yup. I'll admit I've used the longer deadlines to sneak in some time on other projects (gasp!) for my Laptop...

A question from nearly no-tech user:
Would this mean that the "tapes" are going to be handled by more than one physical machine?

Right now, Lando is the only machine actively splitting. However, Bambi is able to/available to split as well. The file system limitations are the problem currently with limiting the number of splitters.

Drop the "if ever" bit. The pending on my P60 is ZERO 99.9999% of the time, Of course it takes 3-5 weeks per wu, so everyone waits for it's return, and the WU is validated credited nearly immediately. LOL

so, if you don't want any pending, get yourselves some Pentium 60 Mhz machines.

Everybody getting geared up and crunching the new 5.28's may be causing some to have more pending WU's...If you crunch 'em fast you have to wait for the rest of the world to catch up...And when a bunch of people started crunching the 5.28's all at the same time...There is going to be a big differential on how soon they get finished.
