I have never been able to get more then 1/2 of the requested credit on my iBook. Why is that and can it be fixed? This is the computer I am talking about https://boinc.bakerlab.org/rosetta/results.php?hostid=936171 Thanks!

Honestly it looks like it is happening with all your machines, not just the one. It looks like it is happening to everyone, not just you. Click on anyone elses name in the left hand column, then view their computers, then click on the tasks and you will see that almost all requested credits are around twice the granted credits. Not everyone lets you view their computers, but enough do to let you see what I mean.

The claims are actually rolled forward into the moving average. That is what granted credit is based upon, average credit claim, across the whole project for that protein, per model. So, *somewhere* in the project you will also find a similar number of TFLOPs crunching that are getting more then their claim (although perhaps just 10% more on a larger number of machines). It's just how the process works.

When you find the machines getting more then their claim it will always raise the question of bias, then a lengthy discussion of benchmarks will ensue. Bottom line is that running Rosetta for that specific protein is a benchmark as well. And some machines and architectures do better at it then others. With another protein and a different mixture of calculations and memory accesses, the tide may turn towards some other environment doing better. The application is not coded nor optimized to have any preferential bias.

In general, L2 cache is very important. And, just recently, the tasks have been using significantly more memory then previously. So making sure BOINC can access enough memory to run the work efficiently is important as well.

have a look at pentium D machines - they tend to get more than requested, i assume because their benchmarks are relatively low.
