Would somebody please explain this concept to me?
I'm brand new to BOINC and do not comprehend what determines granted credit. Do I lose points for not
processing work units immediately or...?
Thanks in advance. :^)

How credit is determined

When your computer completes a result, BOINC determines an amount of claimed credit in one of two ways:

* In general, the claimed credit is the result's CPU time multiplied by the CPU benchmarks as measured by the BOINC software. NOTE: the BOINC software is not optimized for specific processors. Its benchmark numbers may be lower than those produced by other programs.
* Some applications determine claimed credit themselves, and report it to BOINC. This would be the case, for example, with applications that use graphics coprocessors or other non-CPU hardware.

Claimed credit is reported to a project when your computer communicates with its server. The granted credit that you receive may be different from the claimed credit, and there may be a delay of a few hours or days before it is granted. This is because some BOINC projects grant credit only after results have been validated.

Recent Average Credit

Projects maintain two counts of granted credit:

* Total credit: The total number of Cobblestones performed and granted.
* Recent average credit: The average number of Cobblestones per day granted recently. This average decreases by a factor of two every week, according to the algorithm given below.

Both quantities (total and recent average) are maintained for each user, host and team.


Computation credit


the Function for the RAC is a different think............... :)

Greetings back atcha,

Thanks Ulli. Really! The fact that somebody responded is more important to me than the initial query. I realize the "number crunching" board is not the place for questions NOW. Apparently some people are special though... I was on the verge of posting an obscene suggestion to everybody in this snotty clique. Until you intervened. Now I can go to sleep knowing that there is still at least one decent human being left on the planet. No wonder I am searching.

You made my day (better than it was),
Take care!
MOPy :)

THe only time you lose points is if you don't return work befoe the deadline.

If you click on my signature it will take you to 700 pages of material on BOINC, it has a FAQ, search, Glossary ... I recommend it because the material there is more comprehensive than what we can give here in a short answer ...

Paul, is it true that even if you miss a deadline, but are part of the quorum of results, that you will get credit? Another user was asking this in reference to an outage, in which case he had completed the work unit, but could not transmit it because of server problems. I told him that he would still get credit because when the server came back up, his result would be received in the same order as if there had not been an outage. Even if the unit had been reissued immediately following the outage, I assume his would still reach Berkeley as part of the quorum, since it had already been crunched and simply needed to be submitted. In this case, all parties concerned would get credit, including the reissue?

Please correct me if I'm wrong.

Thanks,

Dig,

If the quorum has not been formed, and the system went down, in theory, he should get a chance. Because if the system notices he blew past the deadline it is most likely going to issue new work, and he is going to return NOW, allowing a quorum, and thus it can be formed while the new work is in process.

If a quorum has been formed and credit granted it is also possible to get credit if the canonical result has not been deleted.

Lots of ifs in there. And it is hard to be precise as there are many "it depends"... Since we are all in this for the science and the chance to meet new friends of the opposite sex ... well, credit does not matter ... :)
