Message 313477 - Posted: 22 May 2006, 19:18:01 UTC - in response to Message 312760.  

I wasn't in most of yesterday and then forgot to send a reply.

Here are some statistics that I have pulled together from 3 different computers using different versions of the Seti app:

Genuine Intel (R) Pentium(R) 4 650 CPU 3.40GHz running Microsoft Windows XP Professional Edition, Service Pack 2, (05.01.2600.00)

5.3.12.tx36 BOINC client and standard Seti V4.18 (average of 23 work units)
CPU time = 2,072.61 sec., Claimed credit = 16.81 CS/hr., Granted credit = 23.30 CS/hr.

You must ask yourself why if this computer was running a calibrated client why was it claiming so low.

5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V4.11 (average of 97 work units)
CPU time = 3,110.58 sec., Claimed credit = 34.90 CS/hr., Granted credit = 29.81 CS/hr.


Why was this one claiming so high, the 'magic' figure of 32/unit was for the reference unit which takes 20% to 30% longer than an average 4.18 unit. It should be claiming on average 24 credits

5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V5.11 (average of 34 work units)
CPU time = 12,654.50 sec., Claimed credit = 40.92 CS/hr., Granted credit = 15.71 CS/hr.


Why were you using an old app the first app that should have been used for enhanced was 5.12. Even if you didn't know Crunch3r knew that this app over claimed by 7:3.25. (Why is it still listed on his site?)

5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V5.12 (average of 31 work units)
CPU time = 13,751.11 sec., Claimed credit = 14.38 CS/hr., Granted credit = 14.13 CS/hr.


Got it right at last I see.

Authentic AMD AMD Athlon(tm) 64 Processor 3000+ running Linux 2.6.16-1.2108_FC4

5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V5.12 (average of 11 work units)
CPU time = 9,033.28 sec., Claimed credit = 13.56 CS/hr., Granted credit = 13.93 CS/hr.


Authentic AMD Athlon (tm) 64 Processor 3000+ running Microsoft Windows 2000 Professional Edition, Service Pack 4, (05.00.2195.00)

5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V5.11 (average of 26 work units)
CPU time = 11,120.90 sec., Claimed credit = 53.18 CS/hr., Granted credit = 20.08 CS/hr.

For these two see above.

From the above results, the out and out winner for all of those accused of being credit whores and cheats is the 5.3.12.tx36 BOINC client and Crunch3r’s Seti SSE3 V5.11 combination. This should light up a big bonfire under the backsides of all the self-righteous folks here.

For those using older BOINC clients such as 4.25, 4.43 and 4.45 here is an example of someone using the 4.45 BOINC client with the standard Seti 5.15 app:

Genuine Intel (R) Pentium(R) M processor 1600MHz running Microsoft Windows XP Professional Edition, Service Pack 2, (05.01.2600.00)
CPU time = 79,523.20 sec., Claimed credit = 8.81 CS/hr., Granted credit = 2.56 CS/hr.

NOTE: This was right from WinterKnight’s second example (5.12 14,287s granted 56.46 = 14.23/hr wu id=78922770). So who’s the big bad credit whore and cheat now???


Used standard app and client how can I cheat, I just use a properly configured desktop computer, even if it does have a mobile cpu fitted, no heat no noise. And I gave link to my reference show me yours.

Fun aside; it would be nice if those of us that are running other projects could post their CS/hr here so that we may all compare the data. For the comparison, it would be best that TruXoft’s 5.3.12.tx36 BOINC client and computers as close to the ones mentioned above be used. Averages of 25 to 50 work units would great and more would be better.

My RAC has dropped from 1980 to 1334.

I assume you will withdraw your accusation.

Must agree :)
Strange is that people who has RAC under 100 are so strongly after the Enhanced ;)
If you take average SETI geek he will not be happy to be cut down in the chase.
There are some people who had ex 100.000 credits already half a year ago and RAC of ex 2.000. If you started half a year ago with RAC of ex 2.500 you got in mind that you will some day catch up with them and overtake them :>
I know that some people don't care - so let it be but if you got 30 credits for ex 1h of crunching and now you get ~12 for the same period you could feel unhappy :D
The positive things when it comes to people obsessed with SETI is that they tend to have their application optimised - so work is going faster. Why should I care about SETI servers? They supposed to be happy when they get more WUs/day crunched...
It is only the suggestion but the fair thing would be to clear the scores :P


Everyone on instinct looks at the world and "how does this effect me?" You have to remember that EVERYONE who was using optimized apps for 4.xx is seeing the same thing. Every one of them is seeing the same reduction on their RAC and daily totals. Any chance you had to overtake someone else who was also using the same advantage should still exist!


Yes, but at a much greater time period. Prior to the change I may have had a chance of catching X in 1 year. But with the change that will now take about 3 years or more. And that is assuming that I can maintain the same rate of production. If I do not lose computers for one reason or another.


On an aside, if RAC is meaningless can someone tell me why it is included in the "author's stats" in this forum? Just a curious question here.

And as has been said in a previous post, I could accept that if there was a reset and we all started over at zero. That would be a truly level playing field. Anything short of that is unfair to those of us who spent a lot of time and effort building up what we had.


Agree 100%! If they are not going to fix this new abortion called a credit system, at least reset the stats!

My daily average for each week has always been within 10-15% of my RAC so let's look at it. Oh my goodness, my daily average for the week is dropping at about the same rate as my RAC.

You must be looking at different graphs to what i am.


Okay, let's look at my daily production numbers. Hmmm, daily production has dropped much faster than my RAC or my daily average. Either way you look at it my claim is the same.

*deep sigh*
Daily production isn't a good indicator as it is very dependant on server outages & will be affected considerably by the variable processing times.
Weekly or monthly will give a better idea of what the average daily or hourly crunching is like.
And once again, as mentioned by Eric, those that have been using Optimised applications will see a greater reduction in credit per hour than thouse using the standard application, as the standard application is what his efforts were based on.

I am liking the earlier suggesion of starting over again (since the method changed drastically) more and more.

The drastic change has only been for a small percentage of people. For most people there has been little, if any, change.

Because as these threads have demonstrated, peope like to see numbers representing things. They don't have to be accurate or actually representative, but as long as they're there, people like it.
A more usefull number would be average Work Units per day or hour, but based on a weekly (or better yet) monthly sample. But the problem with that is any fluctuations would be significantly damped (and people seem to get all excited when the see a huge spike, and all worked up when there's a huge drop) & major changes would take a while to show through (although that is the case even now when it comes to accurate information).

It has been fixed. It's just that those that have had the advantage of optimised clients don't like the fix because their advantage has been reduced (at least for now).

Also, I earlier thought that since the credits now are based on mflops it wouldn't matter if you got a low or high AR WU as you got credit for the actual work from the CPU, how ever this has turned out not be the case for some reason...


The impact of low and high AR is even greater with enhanced. You could determine the default credit you get if you pick a wu that has an ar of 0.422 because those are most of the wus.

Try this on for size. Total up all the members here who used optimzed apps for version 4.xx. Guess what......you are in the minority here. No matter how much good you did for the project, crunching massive amounts of data, purchasing more and more equipment, you are still in the minority of users here and cannot dictate to the majority.

And remember I am part of the optimized 4.xx croud also!

Looking at some of the results for one of you machines shows this.

The actual number of floating point operations changes as the angle range changes, that's why some work units go faster than "standard" work, and others take very much longer.

Attn: Grant, Winterknight, Ned, and others with similar posts

No offense, but you guys are sounding like a broken record now - spewing the same retorts over and over, and it's not working. So please, just stop.

At this point, many of us want answers to the issues you are not even willing to address.

Many of us have been crunching SETI for years, and we are very close to pulling the plug right now. What we want and need right now is to hear from a decision maker, like ERIC!

You are not going to convince us that this new credit system is not flawed!

Okay, now I am really confused. When I was quoting my RAC I was being told it was meaningless and that I should be looking at daily or weekly numbers. Now all of a sudden daily numbers are also no good. Well I checked my weekly average as well and it has already dumped by 10% in just 3 days. As my higher production days (which do not mean as much)go off the chart then the weekly numbers will drop dramatically as well. So now which numbers should I look at? No matter which I look at the drop is happening. It may take longer to show on the weekly or monthly numbers but it will happen just the same.

First I thought the credits was fair, but after a little more closely look
I think the credits look "hinky"

For example, isn't is strange that all WUs for one particular PC always almost get the same CS for a WU as someone else who claim about the same amount of credit.

Like my main server almost always both claims and gets a credit around 65 CS per WU. (and this is exactly around 65 for ever WU)
Like this one, it's a very typical WU for that machine.
http://setiathome.berkeley.edu/workunit.php?wuid=78964999

But my other computer the AMD XP almost always gets WUs that have a completely different range of 61 CS per WU (and this is exactly around 61 for ever WU). This is a very typical WU for that computer.
http://setiathome.berkeley.edu/workunit.php?wuid=78500417


And my other computers show the same "effect", I find it a bit weird if nothing else.

That's probably an artifact of the feeder or the scheduler. For instance, your host 1947001 got 9 WUs on 20 May 2006 at 19:02:46 UTC. From the deadlines I think there were only two different angle ranges, so you'd get several WUs in a row with nearly identical times and claims. The same thing happens with each host, the work isn't evenly distributed.

I hope the reduced load on the servers from setiathome_enhanced will allow the project to better randomize the work distribution.

"No offense, but you guys are sounding like a broken record now - spewing the same retorts over and over, and it's not working. So please, just stop... At this point, many of us want answers to the issues you are not even willing to address."

Although I myself am behind the new Enhanced credit system 100%, I'd also like to think that I can see both sides to the issue and I agree that there has been a lot of gobbledy-gook spewed out in these threads. I hope that you guys do get the answers you are seeking from the folks who are actually running the show. It is certainly not an unfair request.

My own analysis shows that I am claiming exactly the same credits here on SETI Enhanced as I am claiming over at Einstein, so in that regard I feel that the new system is equitable. I also believe that it is the people who are running optimized crunchers who have historically gotten the short end of the stick because of low credit claims from the benchmarking method. I feel that Enhanced has addressed that issue in making sure that everyone gets the same reward, regardless of whether they use the standard science application, or an optimized application which gets the work done faster. If all projects moved to the FLOP-counting method at this time there would be much less disparity between them.

If I understand correctly what I have read in these threads, it appears that most people do feel that the new method of rewarding our work is fair and equitable, but it is only the amount of credit being awarded per FLOP that is in dispute. I believe Eric stated in his post that he is continuing to look into this.

Regardless, I hope that for all concerned the matter gets resolved to everyone's satisfaction and the fun of crunching for SETI@home may continue as in the past.

Just my opinion, of course...
