Hi jack

I've just noticed the run times for the current batch of wu's is way off, times like 250 hrs to 500 hrs. The actual run times seem to all be within 40mins to 1 hr.this makes it impossible to download work for other projects(instant high priority) That having been said otherwise they seem to run without problems.

I don't know if these run times are way off. I think the run times of the last batch was more off and the Duration Correction Factor has to regulate itself down again. Downward always goes slow, while upward seems to be instant.
I had 1 successful result so far and 2 errors:
[error] Can't rename output file run_1244025320379086472_2_0
When erroring out, the DCF isn't adjusted downward so I'll have to manually edit the DCF when I keep encountering errors.

Hi Bart I don't know what your DCF was like, on my pc's it was between 97 and 100.I had to knock down to 0.9 before any other project could get work. It still sets DD@Home wu's to around 14 or 15 times longer than they really take.

M4rtyn,

my DCF's were 100 dot something, but decreasing now I've had another good result on both my computers. I think in the end the deadline situation will resolve itself, because the long term debt will go down enough for other projects to get work again before DD does, but it could take some time (a couple of hours in my situation).
Don't know what the exact estimates were when the Wu's came in, around 900 hours or so, while finishing in an hour.
If your estimates are still 15 times too high, you could try to divide your current DCF by 15 again and see what happens.

I Did think about it but it could be a bit risky as some wu's seem to take to be taking a lot longer than the others,Dont want to over do it and get swamped with wu's. Main problem at the moment though is I keep getting the following error on other projects

03/06/2009 16:52:50|Milkyway@home|Sending scheduler request: Requested by user. Requesting 227714 seconds of work, reporting 1 completed tasks
03/06/2009 16:52:52||[error] Proposed work request 842211.148191 bigger than max 436321.745280
03/06/2009 16:52:55|Milkyway@home|Scheduler request succeeded: got 0 new tasks

I've had the same problem at Hydrogen at home, a couple of times never seen it any where else though. detaching and reattaching normally fixes it but it means trashing work in progress and download wu's.
