i know its a touch off topic but

.. what type of recoards arcive are they useing here.. i know at my work we are stuck using a (sorry if i make mistakes typing the name) SQLserver database >a nightmare to sort out or through<

i understand how dificult it is to sort throught databases for a specific refrence. honestly i would love to get credit for any WU's i have that are Maximum CPU time Exceeded... but from my minor ability and knoledge i would look myself at . for my self my stats and spend my own time figureing out the work units that are overlimit time...like thisand mabey post all the ones i could find together in a request for credit.. personaly i run beta projects and alpha projects also so if i loose a job now and then im not going to spend my time huntning down every loss of a credit so i dont expect the scientists to spend there time eithor.

Although.. if the scientists could give us a list of what they would like to see from us to request credit for errored jobs or such it might make it easyer for myself and others to supply the info

Good questions. I do not know the answer to the first, but as for the second don't think they will need anything from us. Right now the problem is that when a WU errors out it is resent to another machine, so it takes quite some time for all of them to drain out of the active data base, and reach the archive. It is my understanding that at that point they can process them for credit. This happened just recently with a bad batch of WUs, and some of them are still floating around on machines with long queues.

I do know that David Kim has increased the time available for a WU to complete and shortened the number of process cycles to be run on each WU to fix this problem. From what I am seeing on my systems it is working. I have been two days without a Max time error on my systems. This of course will make the 1% problem worse as it will take a WU longer to time out. Also some of the longest WUs may still fail.

Fairly easy to search for the affected results, just do a search in the stderr out section of the result for max cpu time exceeded. It might take a bucket load of hrs to complete the search, but then we have contributed a bucket load of cpu time in good faith. David is being very silent on this point.

Live long and crunch.

You should not be having this problem any more. I know they are very interested in this. They have made adjustment to the WUS to fix it. They are now waiting to see if they have killed the problem. If you see any of these please report them so they will know. If they have the problem nailed then they can worry about the credits. Why should they put in the time to process the credits now, and then have to run the process again later if the problem is not yet fixed?

I really do not understand what difference it makes if we get the credit now or a month from now. I for one am willing to wait for the credit until the problem is actually fixed.

Am I missing something here?

Phil

MODERATOR NOTE: I am going to open a thread for Maxt Time Exceeded WU, and make it a sticky for the project team. With your permission I am moving your post to that thread. I will leave this post in its place here.
