Rosetta@Home Question

Hi guys. I posted this a couple of days ago in a stats thread but received no response. I have googled it, but found no answer, unfortunately...



I'm fairly new to Rosetta, and I have got a question. Why is there such a big discrepancy in a WU between "credit claimed" and "credit granted"?

Example: Claimed: 51.57 Granted: 20.00

Does anybody know?

Thanks for your help...

 
sorry for the late reply!

It's normal that you have a differences betzeen the 2 values:
first of all the claimed value is boinc's stock credit system, while the granted credit is rosetta's own credit system. Rosetta awards credit for the real science done by you, boinc by the cpu-time you have spent on it.

Very often rosetta's is lower than boinc's system.

The granted credit is computed by the average of protein structures processed by the first WUs returned on that protein. That means if 2 i7 return the first WUs on that protein they'll ask for instance 100 credits with 100 structures. This average is now the base benchmark. If you now return with your cpu 50 structures on that same protein you'll get 50 credits, 10 structures - 10 credits, ... Everything depends on the benchmark results on the beginning of every protein WU-set.

Having a fairly modern cpu and having your computer always on helps get a closer match. Although varying your WU runtime to find your best solution helps sometimes.
