Dear Sir or Madam,

How often are the stats updated on the team page, and when is credit actually granted in one's account after a work unit has been returned?

Thanks!


Sample of one of my WU's:

The stats are generally updated nearly instant, but I suspect with the demand being more than Dev counted on, this might be somewhat delayed.

As for when credit is granted. There is no set time. Each WU you return must be returned by two other hosts, and the results from each must be verified as scientifically "accurate". What this means, is your data is compared with the others to see that they are near identical. If the three results match, you are granted credit. If not, the "bad" result is resent to another host.

In an instance such as this, credit granted can be delayed by weeks. The scheduler must re-queue the WU, and send it to another host. Then, depending on that hosts CPU speed, WU cache size, and when the host returns the result by, is when your credit is granted. :)

Devil's Advocate - what happens if the re-send returns a bad result?

The scheduler will keep sending out more copies until a limit is met. If there still are not enough sucessfull returns after the limit to the number of copies is met the workunit will be marked invalid and give up on it.
