Hello, I'm so thirlled we've moved to the server assigned credits and understand that'll be tweaked here and there for a bit.

I was just looking up the new credit values and noted that some of my work units are getting the new values (which are much more) and some are getting the old values (which are much less). I keep about 2 days of work units in each machine to smooth out any server downtime (worth doing because though it does happen rarely at least you can keep crunching for most of that time and not need new work). Does that mean that units assigned before a particular time are getting old values and some are getting new and it'll be 2 days or so before full credit is being assigned to all untis? Just checking, thanks.

From what I've seen most tasks I received after some point on August 3rd have all been granted the fixed credit. The only one so far that gave me the old credit was a task that was reissued because the first host never returned it.

That's my experience so far.

Yeah, some of my units are being applied iwth the new system. In fact, I have one computer where most everything has been on the new system. But some of my other systems are getting a mix of new and old scoring systems for work untis being returned even within the last couple of hours. Should I abort all unfinished work units and fetch all new ones? Anyone else seeing this issue? I've got at least three machines (10 cores) affected by this. Three of the other machines seem to be faring better.

AFAIK the method of granting credits is determined with the creation of the WU, unless someone with the projects writes an extra script to fiddle with the database afterwards. Those with the old credits are probably old WUs, perhaps resends or just some who still linger on the machines.

Yes, that's correct workunits previous to 1k1j will get variable credit, and all workinits after that will get fixed credits

It is not an issue!
If you abort...someone else would just get them and have to cover your butt. Just do the work for crying out loud. We all will finish them up in time.
Try to remember why we are really doing this.

Well, of course I"m not going to do it now that they've clarified the odl score is for particular batches of work units. You could imagine a situation where the old scores are being used on units issued before a certain time and if they were reissued now they would get scored under the new system, at which point it would make sense to abort and then anyone who got those would get credited under the new system. Since the server is continuing to assign old credit values for older BATCHES of work units then yes, it would be rude to abort them now and I won't do that. That's why I was seeking clarification. Everyone relax.

You won't be smiling at me Heidi..... I aborted them....., But mainly because it looked like my farm was going to be down for nearly a week (budgetary restraints) and most of them were too near to the deadline - I run a fairly long cache.

Sorry Captain!!! :(

Currently there seems to be one series of results that has way too high credits,
something like : claimed=10, granted=100

Lately there have been credits way too low.
something like : claimed=10 granted=34

Oh, then the higher grant is planned - I assumed that 10/34 was normal.

Never assume anything. I just prefer it to be higher.

I had one task that took 11 minutes to crunch. 2 credits claimed/100 granted. There was only one like that in the few dozen I reviewed.

About a month ago, most of my tasks took about 8 hrs to crunch on my PC, and the ratio was roughly 40/120. Then, there was a batch of much longer tasks where the ratio was 120/200. Now, there is a batch in the 10/100 range. I'm fairly new to the project, so I do not know if fluctuations like this are normal or not. I guess that over the long term, it all averages out?

They sure had a warning with "Code101" in them, I have seen a few of those too.

I guess this catches a condition that should not occur in a regular result, similar to those at SETI where terrestrial signals polluted the Arecibo data.

I reported it in a separate thread, those sure need a special treatment in the science database.

Hi,
I'm crunching docking with a 8 core and till a week ago i got ~10 0000 credits per day. Now since days I got maximum yesterday 500, today 1000 credits, no errors occured, all looks like normal on my server side.

whats up with the creditsystem ?
Is'nt it working ?

Hi,
from the last wu's some blocking my 8 core since 28 hours now.
aborted now..
best would be resetting the project.
think I will quit for a while
bye

Sorry about that, they were possibly part of the incomplete workunits

We had some problems with workinits in the past days, and since the credit is very democratic it assigns the average of what all the volunteers in the past 3 hours were asking for the same type of workunit, that's why it varies from time to time
