Over committted CPUs

(moderation:
I noticed a day or so ago that one of my Q6600 quad cores is overcommitted with E@H. Geez folks, this one's got eight WUs ready to start at an estimated time of 10.5 hours each, and they all have to be done by 1/4/08. The problem is that E@H only gets 5% of my resources for that machine these days. I used to only get two, maybe three at a time; now I'm getting clobbered! I don't think it's too much of a problem since boinc will go into panic mode (EDF) to finish them on time if it needs to. But I wonder if anyone else is having the same problem, and more importantly, why all of a sudden is my boinc getting overcommitted with E@H? Hmmm.

Not likely to be a problem with Einstein per se. Rather, the question is likely to be 'why is the other 95% undercommitted?'.
What is likely to have happened is that your computer asked for work from the other project(s) that have the 95% allocation, and for whatever reason didn't get any. Only then would BOINC turn to old faithful Einstein so that it would have some work - any work - on hand to keep the CPU busy.
You'll have no difficulty finishing the results before deadline, even if, as you say, you need a bit of EDF panic mode to borrow some time from the other project(s). Then it's payback time: BOINC won't fetch any work at all from Einstein, and will concentrate fully on your other project(s), until the resource shares are back in balance. Unless, of course, your other project(s) run out of work again, when the whole cycle will start all over again.

I also had similar problem, Most of my computing effort goes to Seti. With Einstein effectively getting 1hr/cpu/day, which is more than enough to do 1 unit per 14 days per cpu. Unfortunately when Seti was off or had no work available BOINC decided to supply enough work for 2 complete weeks of Einstein units. I ended up aborting 5 units on my pent M and 10 units on my C2D.
And now that I have completed then units I kept, within the deadlines, the Einstein LTD indicates I probably will not download any more Einstein work for about a week.

But that's just the point: all of the other projects are about where they should be in terms of my usual cache. Excuse my french, but sheesh!! :o) I run eight projects on my quads, only 1 of which is offline for now.
Maybe I found a wormhole or other similar inter-spatial flexure perhaps.
