Topic 188988

I'm not sure how extensive a problem this is as it's difficult to track. My most recently added machine received new work units which (since it's fairly fast) were all adding up as valid and pending, so I've been keeping an eye on it to see when the first "granted credits" would appear. So far so good...

On the 16th a granted credit of 86.03 was awarded, but the total credits for the machine was still being reported as 0.00. I figured that this was simply due to a delay in the results server. Then yesterday a second result was granted 78.12 credit, and the TOTAL for the machine was quickly updated to 78.12. As you can see the older result was never credited. Does any one have an explanation of how this could possibly be happening?

Here's the link to the machine:

http://einsteinathome.org/host/104724

notice: Total Credit - 78.12

Here's the link to the results:

http://einsteinathome.org/host/104724/tasks

15 Apr 2005 21:25:58 UTC / 17 Apr 2005 12:19:32 UTC / Success / 19,446.45 / 70.86 / 78.12

15 Apr 2005 13:27:42 UTC / 16 Apr 2005 18:54:45 UTC / Success / 19,451.25 / 70.88 / 86.03

As of now it still hasn't been fixed.
Thanks!

Valid, confirmed results not being added to totals

Three more new results have now been credited, but this oldest one has still not been added to the machine's total:

http://einsteinathome.org/task/3231139

Notice it was even selected as the canonical result:

No answers from the experts?

No ideas anyone?

Is this a consistant problem or an isolated incident?

The total has been way off there since the beginning.

Please explain. In what way?
How is it related to the problem documented above?
Please post details.

Remeber that a team only gets credit form a participant during the time a participant is part of the team. If i have 1,000 credits and join a team, those credits will not be added to the team total.
Likewise if a participant quits a team the team will keep the credit that participant earned during the time he or she was part of the team.

I hope this makes sense.

Ok so that is how it

Ok so that is how it works.

I was not on a team at first and when I joined the one I am on I figured they would add my total to the total of the group.

Ok, this team issue is solved and anyway has nothing to do with the original problem outlined in my first 2 posts of this thread.

Any explanation for the credits missing from the total for the computer?

Thought I'd add a final

Thought I'd add a final update to this. 17 results have now been awarded credit for this machine:

http://einsteinathome.org/host/104724

Of those, only the last 16 have been added to the total. This one still has not:

http://einsteinathome.org/task/3231139

Einstein is clearly not doing his math correctly. I'm not going to track this anymore as it's obviously not just a delayed update at this point. No one has attempted to offer a reason for this, or even a comment, so I assume nobody cares that there's a problem in compiling the result totals. Leaves me feeling that reporting bugs is pretty much a waste of time, unless it's in regard to the all important screensaver. :-)

I see exactly what you are talking about. I added your 17 results up with a calculator and indeed your total credit falls short by 86.03, the amount of this work unit. The credit was granted but never added to your total. I wish i had an answer for you. Hopefully this isn't something that happens all the time. We'd never know about it if it does, since past results are deleted from our pages. That one will be gone soon too, so hopefully someone will address this for you before it disappears.

Just to say: It's not that we

Just to say: It's not that we don't care, but I have to admit that I don't have any explanation for this yet. The only idea I have so far is that the credits got lost in one of database crashes we had (see news...), but that doesn't satisfy even myself.

I can confirm that the

I can confirm that the problem is a real one:

mysql> select sum(result.granted_credit) from result join workunit where result.hostid=104724 and workunit.id=result.workunitid and workunit.canonical_resultid!=0;+----------------------------+
| sum(result.granted_credit) |
+----------------------------+
| 1265.2366171823 |
+----------------------------+
1 row in set (0.01 sec)

whereas the total credit shown for the machine is 1179.21. The difference is exactly the 86.03 of missing credit.

I'll talk with David Anderson about this and see if I can understand what's gone wrong. It may be some subtle database-access/locking related bug.

Thanks very much for pointing this out. You have sharp eyes!

Cheers,
Bruce
