Thanks for that link. I see what you mean though. Reminds me of reading the tax code! Oh my aching head!

Since BOINC is open-source, everyone can easily look on the code, and additionally where's a wiki-page detailing the credit-system... ... but while it's easy to look on the wiki-page (or the code), understanding the credit-system is much harder... The wiki-page detailing CreditNew are here: http://boinc.berkeley.edu/trac/wiki/CreditNew Yes - thank you for the link. It doesn't seem that complex until you get to the various normalizations that are done. It might be a good thing for people to look at for those who are concerned with points allocations. I'm not clear on how you get the wide variation in allocated points Movieman is talking about but I did only skim the entry.   |

The issue that I see seems to be related to the Claim part of this.
----------------------------------------If it were wu related and the job was particularly difficult then, when there is a wingman, I would expect that he too was struggling. observation says otherwise. The sometimes 10 fold difference between wu's points claimed doesn't seem to be the result of failures or aborts either else all would be similar... wouldn't they??  |

Almost all of my FAHV(Vina) workunits are single redundancy which means no wingman. On these I always get exactly what I claim for points. On the few that require a wingman, we are generally pretty close in claims and granted. Even though most are single redundancy, they still vary widely, which means the differing points per hour are a result of the crunching process contained in a particular unit. Some units are crunched more efficiently than others, thus garnering more points per hour. Makes complete sense to me. Cheers

Not to nitpick, but wouldn't 'no wingman' be zero rather than single redundancy?
----------------------------------------Back on topic though, I don't understand how differences in efficiency would account for 10x the difference in pph. |

Back on topic though, I don't understand how differences in efficiency would account for 10x the difference in pph. Efficiency, as I understand it, is the amount of work done over a given amount of time. Work/Hour = 1 and (10 times Work)/Hour would result in 10(1), thus 10 times as many points per hour. Cheers

I noticed a strange behaviour with the fluctuating points per hour for Vina's. Usually I upload tasks after they are finished, so basically one at a time. And the claimed credits are all over the place. But now that the server temporary has upload problems, tasks are uploaded in batches. The claimed points for these batches are suddenly rock solid. How is that possible? It would suggest that the moment at which points are reported is a factor in the calculation. But time should not be a factor, or should it? Has anyone else noticed this behaviour?

Set to upload in one go in preferences here so we will see

It doesn't matter to me. I'm using the Phenom-node for warming up my feet (souterrain w/o floor heating) and the difference between full load and idling isn't that big on my i5-Workstation.

Just uploaded 30 faah vina's in one go. Lowest points per hour is 24.8 and highest is 25.0. Practically nothing between them. So wu's that are reported simultaneously get the same points. Spread out over time they get different points. Very strange.
