bug or feature?

Yes ... :)

The credit baseline has been increased and the bonus reduced, so people don't get mad if they miss a bonus ;)
Edit: further details here.

What the heck does the amount of Credit have to do with when the WU is returned, it should have absolutely nothing to do with it. I always thought X amount of Credit was supposed to be given for X Amount of work. I also thought the Credit was increased in the 1st Place a few weeks ago because the Project was or had been giving out less than it was supposed to in relationship to Dr. A & his Almighty SETI Project.

This Project is just shooting it's self in the Foot with all this X amount of Credit because it supposedly wasn't giving out enough & then changing it 2 weeks later to a lesser amount again. It will be interesting to see what the Milkyway Project gives in relation to the GPUGrid project when they come out with their NVIDIA Application.

" then changing it 2 weeks later to a lesser amount again"

The differnce is in the timing of the changes they have made to the credit calculations which are apparently tied to when the WU was sent out and to the science version.

What you are considering the "lesser" amount, I believe, really is the *bonus* for returns in X amount of time. Yes, there has been a lot of churn recently, the base switch to 2X flops to then 2.4X flops and also another set of changes on the bouns credit from 50% if returned within 24 hours to 25% if returned within 48 hours. Hopefully they will settle down and within a week all the old WU and application versions will have been completed so people will stop seeing the direct comparisons between old and new and begin to realize the benefits of the current credit calculations.

the benefits of the current credit calculations

That would be over @ the Milkyway project I take it ... :P

Take a look at your *claimed* credit from last week and this week ... this week is much higher which is the result of the base multi moving from 2 to 2.4.

The bonus credits which are added to your claimed credits to arrive at the granted credits amount have been explained as an incentive to return results quickly as this project streams the results from one batch of WUs into the next batch of WUs so quick turnarounds are very important. Last week the bonus was 50% for 24 hour turn and this week it is now 25% for 48 hour turn because lots of people did not think the 50% on one day was attainable for most given the current configuration limitations in BOINC. This created a conflicting goal for individuals who are more concerned with PPD thatn the science to consider aborting cached WUs that would not be returned within 24 hours.

If you have been returning WUs within24 hours then the net is almost nothing between the base increase to 2.4X and the bonus decrease to 25%.

Although I am not crunching just for credits, please do let us know the hr vs. hr credit comparison between GPUGrid and MW.

Poorboy,

you may want to start reading about here in the thread which I linked to, or maybe some posts before this one. If you understand what's written there all the questions which you posted will be answered.

@snow: If I remember correctly the initial change was base credit x 1.5, with a 50% bonus for 24h and 20% for 48h. Now we went to base x2 with a bonus of 25% within 48h.

From what I read it's just keeping everybody in mass confusion on just what was being given & what will be given now & what will be given later on as soon as somebody gets a itch to change it again ... Maybe I'll live long enough to Decipher it all some day though :)

I was happy with the way it was and wasn't complaining about the Credits 1 bit, the thing I'm complaining now about is that it's one way one week & then another the next, or so it looks that way to me anyway.

It's not even close with the Milkyway Project giving out more Credit on about a 3 to 1 Ratio at least even with the increased Credits here, but according to the MWay Project there are other factors involved for that Credit difference between the 2 Projects.

ooh yes, it's the "travis is fixing it again" factor that has to pay extra..

<ROFLMAO>

Well.. no. Just give it a few days to settle in and possible bugs to be sorted out. Then you can forget the entire credit policy history and you don't have to be confused any more.

The change was made for a good reason (explained / named in the post I linked to), but the actual values needed to be readjusted for better balance. A bug was found in the calculation and is hopefully corrected. These changes were not made out of a strange mood, they're here to benefit us all: credits in line with seti for us and a faster "supercomputer" for GPU-Grid.

We understand that there were too many changes in credits in these weeks. These have been the very first substantial one since the beginning of the project.

As there is also seti now for GPU, we had to align with them and return more credits. To do that we had to update the applications, like yesterday.

All the adjustments were done upwards, now you get 2.5x if you return fast, but only 2x if you return later. The average should be somewhere less than 2.4x, so fine.

Now, we are set. The new scheme also benefit science (with fast returns).
Now, happy crunching. no more changes.

Until we change again ... :)

Seriously ... not a problem ...

Though as one that was turing around most of my tasks all the time in 24 hours or less it matters not that much to me ... the trick is to have more than one GPU in a system ... :)

Faster ones helps too ...

But, regardless of bonus or not, my 9800GT is here and working though I will bet I almost never get the bonus for work done on that system. It does make me want to replace it ... or at least put it into a system with other GPUs so that I can get my average up ...

Personally, I think GDF and the rest of the staff have done a reasonable job trying to explain what is going on and why ... and I thank them for that ...

Credits in line with SETI has never Benefited any anybody except for the SETI Crunchers ...;)

I'll put it more precise then: credits per flop in line with SETI ;)

So, what's the final word on credits. I'm still getting 1.25X on returns within 24 hours since April 19. It was 1.6X prior to that.

The last word is that there hasn't been a readjustment for some time and I wouldn't expect any to happen. The credit baseline has been increased and the bonus reduced, so in the end you get the same credits (compared to the 1.6x version) for early returns and more for late returns (so it's not that important if you miss the bonus every now and then).
