I am using a G5 iMac with OS 10.4.7
For most of my time working on Rosetta, submitted credit and granted credit have been the same. For the last month only 50-33% of my submitted credit has been granted.
2. Rosetta recommend BOINC 5.2.5 for Macs.
Boinc recommend 5.4.9 the version I'm using, who is right?

I think you should be fine with either BOINC version.

Rosetta implemented a new credit system in that timeframe. And what has come up is that on a Mac, the benchmarks run very quickly, and so they presume the machine will crunch well, and yet Rosetta doesn't run as fast as predicted by the benchmark. The new credit system grants credit for the number of models you've crunched. And since the Rosetta models don't compute on par with the BOINC benchmarks, you see a disparity between your claimed credit and your granted credit.

Just this week they added a mention on the site that says:

Note: the Mac OS X (PPC) application is not optimized and will not fully utilize the PPC processor.

"PPC" means Power PC.

Surely there must be some MAC Rosetta crunchers who are capable of optimising the PPC applications. It seems wasteful for MAC's to be only computing at 1/3 to 1/2 the performance rates.

so this problem has no solution?

If so, I won't run rosetta on Mac any more, it's a waste of energy.

sorry to say that.

Get an intel Mac ;-)

I think there where some people looking at it (someone mentioned Team-MacNN) but you are still doiong JUST as much science as you where before that has not changed, before you where just getting more credit for it.

Is it not possible for a MAC to run multiple tasks in parallel to fully utilize the bench mark speed.

morrisian,

you are right: the Mac client is not optimized at all and therefore needs almost twice as much time for the same amount of calculations. Since they changed the credit system this directly converts to credit as well, because credit is granted according to the number of calculations you do.
