6.36 time crunched for 225.9 claimed
6.48 time crunched for 199.8 claimed
This does not compute, more time crunched, less points claimed. Both are from the same computer. How is this possible? Will wait for granted before I get to steamed up.

Re: Points don't look right

Every few days boinc runs a benchmark on your system to figure out approximately how much work your system does. So, my guess is that boinc recently ran a benchmark on your system and it thinks it can do more work then last time it ran the benchmark.

Using new benchmark
225.9/6.36 = 35.5 pts per hr

using old benchmark
176.7/5.73 = 30.8 pts per hr
199.8/6.48 = 30.8 pts per hr

So now all of your WUs will ask for 15% more credit per hr of work. :)

Re: Points don't look right

You may not feel better after you see the points awarded. The points-allocation algorithm used when one wingman doesn't finish all 16 jobs in the WU doesn't seem to work very well given the very unequal computing demands of the individal jobs.

Here's a link to a thread in which Crystal Pellet explains the calculation:

Re: Points don't look right

Kate,

This calculation only applies if the two wingman did an unequal number of jobs/attempts/positions.

As for Bearcat prepping to get steamed up, he's the one at the wheel feeding his own oven ... in the know what he did between the 29th and the 2nd to that client to suddenly have 15% bigger claim due a change of benchmark, as anhhai correctly "did compute!". Him torquing the CPU cycles (OCing) could have done that, but another dozen things only Bearcat knows could have done it too. Vaguely remember a discussion recently of someone finding his/her CPU to not stick to max speed :P

Re: Points don't look right

Why are so many concerned about "points"? Aren't we here to find cures and other things to benefit mankind and/or make our planet better?

On this particular box, its a dual dual core 2 ghz xeon woodcrest with 4 gb memory. This one has not had any throttling issues as my westmere box has. Zero OC or anything else. Shouldnt have changed by much but since i run clean water and CEP2 one at a time. My guess will be since CEP2 writes allot to disk, CEP2 is slowing down boinc in general. This box does nothing but crunch 24/7. Already found granted points similar to my post. Thanks for the replys.

Nanoprobe, its about efficiency. In this day and age, waste is expensive. if i determine a project is wasting cycles, like CEP2 does IMHO, then its time to move on to something that doesnt. been here long enough to know between getting the bugs out to something thats wasteful.

No replies needed anymore here. I will move on to something else!

Re: Points don't look right

Bearcat, wouldn't results per amount of time crunched be a better barometer of effeciency than points? I agree with you 100% that CEP2's effeciency is less than stellar but I guess it's up to the individual to decide if the costs outweigh the benefits or vice versa. I am one of the fortunate ones that has not had issues running CEP2. Hopefully some time in the near future there will be some modifications to the code for CEP2 that will make it more efficient. I apologize if upset you. That was not my intention. We are all in this together. peace

Re: Points don't look right

nanoprobe, WUs/hr is not a good barometer because WU size vary so much, but the work still needs to be done. Pts is a good barometer. Let me give you an example. One of my PC will get only around 8 pts per hr crunching HFCC and HPF2. However, it get 15 pts per hr for everything else (except CEP2). This tells me that I should not run HFCC or HPF2 on it. For other machines most project can run fairly well on it. But if I want to optimize, I look at how efficient my system compares to others by the way of pts.


Edit: this is assuming the same OS. Because Linux efficiency is different from windows, you have to compare linuxes boxes to linuxes boxes. windows boxes to windows boxes

Re: Points don't look right

anhhai, I'm afraid were going to have to agree to disagree on this one and here is why I believe points by projects per machine is a bad comparison because results should always trump points. Using Windows to crunch will award more points per hour but Linux will do more WU per hour. Twice as many when running HCC for far less than twice the points. To me it doesn't matter how many points per hour either of them award. If you run machines that are solely dedicated to crunching and you want the maximum efficiency, which in my book equals results completed, then Linux is the most efficient by far IMHO. Look at my sig for example. I'm almost 150 places higher in ranking when comparing results to points and results is why I do this.

Re: Points don't look right

nanoprobe, I said assuming the same OS. We all know that linux is better at doing work. Comparing pts between Linux machines and windows machines is a worthless exercise and just gets people made at how wrong it is.
Ranking is also a very misleading. You can do several HCC WU or 1 CEP2 WU. But it doesn't matter, crunch whatever you like. Do what makes you happy.
