1) Message boards : Number crunching : The Year of the Ox Challenge (Message 13192)

Another big reason is definitely the collision with the Charity Crunch event initiated by the two top teams of 2008 Challenge Series (i.e. L'Alliance Francophone and SETI.Germany). Looking at the scoreboard, you'll indeed find not as many members of AF and even less members of SG as in the last comparable challenges. Thank you for posting a full tentative schedule for 2009, this will help to avoid such collisions in future. :)

Yes, that collision with the Charity Crunching (Benefizcrunchen) is the reason for me not to take part in this PG challenge. I enjoyed those challenges in which I took part. But I think 9 challenges in 1 year is quite much for a single project.

This is a tight challenge. I hope the validator and the stats can keep running fast enough so that we see what the standing is - there seems to have been a major lag this afternoon.

In order to speed up the clean up process, would it be possible to first resend those workunits for which (exactly) one success was reached before the end of the challenge, before sending workunits for which there was no success (e. g. because both tasks were aborted)?

I just looked through my WUs and suspended all of them which have no successful result sent and returned during the challenge, so I'm doing only "clean up work" at the moment. :)

That's a good point, thanks. I am going to do that check on my WUs occasionally, too.

I have noticed that some WUs have been sent out another time although there were two other tasks for that WU that were not failed/aborted. What is the reason for this 3rd calculation of a WU?

Thanks for your effort to offer such challenges! They make crunching more fun.

FYI...over 12,000 WU's were aborted during and shortly after the Challenge. While not necessarily a bad thing, it will make the clean up process that much longer. :( 3 days might be too agressive so anticipate closer to 6 days.

In order to speed up the clean up process, would it be possible to first resend those workunits for which (exactly) one success was reached before the end of the challenge, before sending workunits for which there was no success (e. g. because both tasks were aborted)?

Another point: The workunit processing apparently can end with an error (missing file) when paused and resumed.
