Short credits

[Melanie]

Greetings all,
I have noticed quite a few very short wu's that only yield 14 - 20 credits. Does any one know what these are. It is a bit bizarre that some days I get lots of astropulse work for hundreds of points then get a load of 15 pointers ??? Are these mini crunches or is something up with my set up?

Hi Melanie
I don't do much seti but most projects don't have set times for wu's
Theres nothing wrong your end  :D
You should try a few ABC's ...anything from 30 mins up to 24 hours  :lol:
The lowest i had was 30 credits and anything over 7 1/2 hours gives me 1000

On your account page at Seti you can set preferences for the project to send you  "SETI@home Enhanced" and/or "Astropulse", sounds like you get both, the "enhanced" are the short ones.

Thanks for that guys. The normal enhansed WU are about 45 credits which was why  I was wondering what these 15 points are. Maybe they are just WU's without much info in them, I guess some parts of space are just empty !!!

Some of the WU's running on the Nvida graphics cards are around 15 credits for 1 min of cpu time and the longer ones 60+ credits for 4 mins.

hmm thats interesting, I downloaded the cuda drivers and the beta test but couldnot get it to work at all so went back to the normal version, I wonder if some of the units are working under cuda? surely not if I don't have the updated Boinc ? is there a way to tell?

Hi

Assuming this is you, then no, you're not running the cuda app.
The difference in credit awards is down solely to the angle range of the work units. If you look at yours results, the higher credit WUs have angle ranges like 0.2 or  0.4 and give around 45 credits whereas the "shorties" have angle ranges  >2.0  and give about 14 or 15 credits. They also take much less time to run

Many thanks ,
