1) Message boards : LHC@home Science : screensaver/graphics bug (Message 23237)
Posted 24 Sep 2011 by Profile Nawiedzony
Post:

I do agree that visual attraction is important. We plan to resurect the screen saver, but it should not be coupled to the program any more.


Maybe it will be enough to give an animation of particles speeding in the LHC tunnel, animated WU progress bar and some small but interesting pictures connected with CERN. This will not affect the calculation of WU and should be attractive.

LHC is awarding proper credit. Primegrid is awarding too much credit. Primegrid should change, not LHC.


So compare to other projects and You most often will get credit/s value 1.5-2.3 times higher than in SixTrack.

I think LHC is giving too low credits to theirs participants.
For example:

about 0.01615 cretit per second
it is 3 times more than in LHC
(on the same PC)



I know LHC is very important project for science and I do not participate for credits, but I think LHC should reward it's participants with higher credits, like others project do.
Of course it is no high priority for admins, but they should look at this in near future...

Also LHC scoring is very low, for example:

188.9s/1 credit

only 94.7s/1 credit, so in 188.9s it will give 2 credits

I think I noticed something important:
All my WU that got the status valid, are calculated on another PC with the same operating system as mine (winXP)
All my WU that got status inconclusive, are calculated on another PC with a different operating system than mine.

Is it important information?

Recently my PC counted several WU (with typical remaining time), but the validator did something like this:

Is there any explanation or is it just an accident?
