It really isn't a good idea to look at the credit granted.
2 WUs
Runtime  Credit
270.46   120.02
272.46    70.93


An extra 2 seconds gets 49 less Credits.
:-/

That's Credit Screw for you. :-(

But watch how everyone's RAC goes up while those GBT tasks dry up. ;-)

Cheers.

That doesn't mean much, the task could have been suspended while other tasks ran, or the computer was shutdown.

That's not too good. Worth to observe if it's rare event or frequently occuring one.
Seems this particular task almost finished and then was restarted at 100%.
Can be just coincidence (if rare) or some problems on task finalization(if frequently occuring).
Also, restart wasn't fully correct cause BOINC client lost info about task duration and reported only length of run after restart.

This can be emulated by completing task offline then copying all corresponding files back to BOINC folder.
That way BOINC will restart from last checkpoint (~100%) but will not have any real info about task duration.
Time printed in stderr app's own measurement and has no connection with BOINC's ones.

But, I must admit that the kitties are luvin' this all Aerecibo kibble diet.

With no BLC data currently I would imagine the campus bandwidth will be higher than normal. Would be interesting to know how much higher but I think this would be hard to measure

Well, I don't know if that is strictly true, but I do know that my 2 machines, which were doing about 50-55K and 70-75K RAC/day , respectively, have bumped up to roughly 75K and 100K the last 3 days after the GBT WUs ran out, and I've gotten only a handful of APs, so that's mostly due to the lack of GBT.

It is the measure of the feeling we have already sensed that GBTs make us sweat more, but bring less credit.
The possible reasons have been discussed here by Raistmer et alii.
Probably, already people using the Linux Special application may have a different feeling.

Crunch on!

Well, yeah, and this should have been anticipated by one and all - after all, the current apps were written for Arecibo data, and therefore somewhat "optimized" (by default) for whatever characteristics that data had (at an unconscious level). So the GB data is not "optimal" for the app, and, naturally, has different characteristics, and therefore poorer computing characteristics for the app. The Linux app has been reoptimized for the GB data, and you see what improvements could be made if the Arecibo app had been tuned for GB, which it (seemingly) wasn't, just made to run on the GB data.

Too bad...
