i have a computer that all it does is SETI, now my account info says that I did a packet of 14,081 and claimed 46.07 but end credit was 17.79. Now my q is why is my computer claiming so hight a credit?

I found the result you were referring to and there are two reasons:-

1. You are running version 4.19 of Boinc which is well known to overclaim.
2. All the other members of your quorum were running multi-CPU boxes and these seem to seriously underclaim (look particularly at the 4cpu Xeon which claimed less than 5).

At the end of the day you got a bit less than fair, which would be more in the 20 - 25 range.

I think you might find this link to the WIKI helpful

Thank you for the link but it still does not explane the differance between 46 and 17, i'm running a 2x MP2100 with a weak vid card. i'm not a computer smart person to start with.. any help would be great

Cliff - what your computer claims is seldom what it actually is awarded. The other computers crunching help determine the awarded credit. As I recall, they toss the high and low numbers and average the two remaining numbers. If you're overclaiming, as asserted by an earlier poster, then your wu may well be the high getting tossed. Either way, you're getting an "average" of the four numbers being submitted.

Hi Cliff
A few things

• 1. turn off Boinc/project graphics and screensavers. It runs a lot faster.
  
• 2. The claimed credit is calculated from the benchmark and time to crunch. Usually when the third result is in they throw out the top and bottom claimed figures and give everybody the centre figure.
  
• 2a. Benchmark - you will see figures for integer and floationg point when benchmark has run (Boinc/manager/run benchmark) but it will run automatically on version change and every 5days approx.
  
• 3. Look on this board for optimized seti clients by Tetsuji Maverick Rai. They will decrease time to crunch a unit very significantly
  
• 4 For any questions you may have look in Paul's Wiki first using the search function.
  

Have fun

BOINC 4.19 claimed more credit based on the benchmark scores. That was fixed in 4.45 (maybe earlier, I forget). The optimized clients sometimes claim more credit also (as mine does). Some optimized clients claim less credit. It varies because of the way that the client was compiled. I don't normally get what I claim. I usually get less.

Benchmark scores vary because of different client version, cpu types (& speeds), L2 cache, RAM, motherboards... there's some of it, but hopefully you get my drift here.

A standard 4.45 client (for example) may claim 10
A optimized 4.45 client (for example) may claim 7 or 20

If I missed something here someone will correct me or better explain this.

I hope that this helps you. :-)

No matter where you go, there you are...

Because of optimized clients credits should be based on the mean and not the median.

Nah, that would take away one of the reasons for having a quorum. A faker claiming 10000 credits would get 3333+ credits awarded.
