I haven't used Rosetta in a while, so I was wondering if my credit is normal, it seems kind of low. Average WU takes about 10K secs per thread with an i7 920 at 3.6Ghz, with about an average of 60 credits each. That means 24(hours in a day)*3600(seconds in an hour)*8(threads)*60 (credits per WU)/10000(seconds to finish WU per thread) = ~4000 credits per day. This seem to mesh with what the rest of you are getting? Thanks.

Not for me, you are actually getting more credits than I am! I have 2 pc's and one of them is doing this:
10,639.33(time to crunch) 22.69(requested credits) 13.88(granted credits)
The other pc is doing this:
10,447.70(time to crunch) 28.78(requested credits) 37.95(granted credits)

The 1st pc is a 3.4ghz dual core while the 2nd is a 2.8ghz dual core, the 1st has 2 gig of ram while the 2nd has 4 gig of ram in it.

Can someone explain to me how credit is worked out. Nearly all my workunit granted credit is way below what is claimed.
For example
https://boinc.bakerlab.org/rosetta workunit.php?wuid=343084200
CPU Time 17,069.93 Claimed Credit 96.74 Granted Credit 0.46

Geoff, the task that your mention is likely a long-running model, see the thread sited and the discussion there about credit and fairness and averages and benefit to science and the project.

I only see two tasks with extremely low credit. One had what I can double headers. For whatever reason, these only seem to grant credit for the last set of headers (2 models in both of your cases). If you can help the developers understand what was going on with your machine at the time these ran, that might help track down that problem.

This is from the BOINC Messages for one of the very low credit tasks

As can be seen from this I am at present running 3 projects, Rosetta, Climate Prediction and Einstein which means that tasks will be suspended and restarted as resources are shared between projects.
The previous task that restarted at 10:54:58 and finished at 10:56:22 did not receive low credit.
The task that received low credit started at 10:56:22 then restarted at 17:05:37 and finished at 17:07:23

I hope this may be of some help

Geoff.

Geoff, how do you have the setting for leave tasks in memory while suspended? This is the checkbox on the disk/memory tab of the preferences.

Unticked, so the tasks are removed from memory and forced to restart from a preserved checkpoint each time. Good to know. Thanks.

I am uncertain if that is related to the problem at all, but it could be, so I wanted to ask. Also, unless your are having other problems using your machine or something, BOINC generally gets a tad more work done if you check the box. That way suspended tasks get swapped out to the page file and can resume where they left off, regardless of last checkpoint... although I believe the BOINC Manager is now much better at only preempting tasks after they checkpoint, so that is probably less of an issue then it used to be.
