Welcome to Rosetta@Home.

To merge computers they have to be exactly the same, this includes the Operating System. So these computers will not merge.

D'OH! well anway I'll be running mostly on the Vista installation

thanks for the clarification and the welcome

Carlos,

If Rosetta wasn't using your CPU time, what was?? Sometimes another program gets stuck and steals all the cycles. Another thing that has happened to me once or twice is that the system idle process takes the cycles, and BOINC makes no move to use them. When this happens, I shut down BOINC, and then restart it (ie give it a kick in the pants)... that almost always gets it going again.

Good luck!

I wrote an internal benchmark for Rosetta last week, and Rom now has a version that uses this to compute credits. Rom suggests however that we wait until after CASP to deploy it because it may take a few iterations to make it acceptable to everybody. I don't know how difficult it will be to "get it right", but I'd like to start testing it on Ralph soon.

The new version soon to appear on ralph will also have a fix Rom put in for graphics problems; as reported on the boards, a good fraction of the errors seem to be associated with the graphics (I suspect the fact that they consume lots of memory is part of the problem), and in the new versions graphics related errors should abort the graphics but not disrupt completion of the Rosetta calculation.

Credit reporting 
By default, the claimed credit of a result is based on the product of its total CPU time and the benchmark values obtained by the core client. This can produce results that are too low if the application uses processor-specific optimizations not present in the core client, is compiled with different compiler settings, or uses a GPU or other non-CPU computing resource. To handle such cases, the following functions can be used. 

void boinc_ops_per_cpu_second(double floating_point_ops, double integer_ops); 

This reports the results of an application-specific benchmark, expressed as number of floating-point and integer operations per CPU second. 
void boinc_ops_cumulative(double floating_point_ops, double integer_ops); 

This reports the total number of floating-point and integer operations since the start of the result. It must be called just before boinc_finish(), and optionally at intermediate points. 

...

Recent progress in the BOINC world is towards awarding credits based on real work done (which I expect to upset some people accustomed to ultra-high benchmarks fitting in L2 cache, as in the case of real science apps accessing memory, often 3GHz and 2GHz PCs might actually doing roughly the same amount of real work per unit of time).

I do hope that Rosetta moves towards this model soon :-) I have two PCs, one AMD, one Intel, both are roughly similar in speed, but the AMD appears to get twice the credit (on Rosetta) that the Intel does. The other projects I crunch for (CPDN, Seasonal, BBC/CCE) all give points based on the work unit rather than the benchmarks, which I think is a 'good thing'.

Incidentally, I noticed that the credits per work unit have gone up by 50% or so on the Intel box since 5.16, which makes things fairer I feel. I haven't run Rosetta on the higher-scoring AMD recently so can't compare, since it's currently dedicated exclusively to a 3 month work unit...

Here's 6 of them, this individual is scaming the credit system bigtime!!!!

A question for members of the teams vying for dominance--Rom is currently working on an a benchmark internal to the rosetta code that will ultimately used in calculating credits. would you like to see this on rosetta@home sooner or later?

Sooner. Absolutely without question. Just make it fair.

Please make the benchmark balanced between windows & linux.

33 TFLOPS go baby go!!
