I was checking the status of BOINC on my computer a few minutes ago and noticed that BOINC has been crunching SETI units out of order. It doesn't appear to be much of a problem for due dates since there aren't many with the early deadline left, but if it keeps doing that it could end up a problem or be a problem for others.

Currently on the work tab I have 3 units showing they have been fully crunched (and turned in) with a deadline of 2004-09-15 @20:23:20. The one being crunched currently has the same deadline. In addition, there are 7 more workunits with the same deadline that have not yet been processed at all.

There are 20 units with deadlines of 2004-09-21 @19:21:04 and 19:20:05, with 20 more due about 10 minutes later and another 10 due about 10 minutes after that. There are 20 more workunits that have deadlines of 2004-09-22 @ 02:17:28 and 02:17:29. Two of those workunits with the latest deadline (ending in 29 have already been processed and turned in even though though all but 4 other workunits are due before them of which a substantial amount are due an entire week before them.

I'm running BOINC 4.05 on WinXP SP2 on an AMD system. My other computer hasn't been processing units apparently since I forgot to log it back in a few days ago after it was turned off so I don't know much more than this computer is telling me.

Last group of wu's I got was 20 with a deadline of 2004-09-15 and 20 with a deadline of 2004-09-16. So far I haven't noticed any processing out of order, and 10 of the wu's due the 15th are finished and reported.

Only difference apparently between our system are the OS (and perhabs the type of AMD CPU), I'm running Win2k pro SP3.

Hmm. Hopefully your system remembers to take the deadlines into account.

How many days have you set "Connect to network about every" to? (and how many days do you estimate you have work for now?)

Well I don't really know what the cause of it is, but I would imagine that the software is somehow misreading something. My computer is always connected to the internet so it connects to the server whenever it wants/needs to. Looks like when I wrote that I had about 75 unprocessed units which at a little under 3 hours per unit puts me at 225 hours which is just a little over 9 days I think. So I have about 9 days of work in theory. In reality that 9 will probably be more like 7-8. Maybe less I don't know for sure. In any event, it shouldn't be a problem on my computer unless it finishes processing the early deadline units after EVERY other workunit which I doubt. Even then it *may* be ok. It's only done 2 out of order. I've never really noticed it have this problem before so that's all I can really say. Something caused it, whether it be a bug or some really wierd fluke. And like I said, it probably won't effect me any, but I'm worried that if it really is a bug in the software it could happen again (and perhaps more severely so that it does effect me) and for others who really would be effected by it.
