I still have hosts that were retired as early as 2005 I can't delete from my hostlist due to pending results, either from my own hosts or others.

the answer depends entirely on your definition of the term "ordinary matter". :P

not sure what is going on with that machine.
it's running linux, Boinc is reporting application version 4.66 for his results, but the stderr.out looks like he is trying to run 4.65

<core_client_version>5.2.13</core_client_version>
<stderr_txt>
boinc_init() 4.65
boinc_finish(0)
</stderr_txt>

maybe someone that's trying to use an app_info.xml on a project that doesn't have "alternate" versions of the science application?

Doing our part, and sacrificing WU completion time for accuracy from our systems is critical.

We wouldnt want to provide erroneus data and have LHC accidently create a black hole.

Sorry for my bad English, I am American.

Keep on Crushing !!!

Sepionet,

people trying to "cheat" on RAC and people returning invalid work to a project are two totally different things.
The answer to your original question is not in cheating, but in returning invalid results.

So, let's take a look at invalid results.
Unfortunately LHC@Home is not showing the "stderr out" info for results, so we can't analyze that for errors.
But there is something else we can look at, namely result runtimes.
Your slightly overclocked computer is taking a lot less time to compute a result than a comparable computer.
For LHC short computing times usually mean the beam/particle trajectory is set on a crash-course.
If one computer puts the beam/particle on a crash-course, while the other computers calculating the same result don't, something in that one computer is causing the calculations to return a different answer than what is to be expected.
This difference can be caused by a different brand or model processor or by an error in (for example) the floating point unit of a processor, either a design error, a manufacturing error or just plain overclocking.
Under normal usage of this "faulty" cpu, those errors might never show up (think back to the early Pentiums), but when running specific applications that require a high precision and accuracy in their calculations they will show up, even if they "only" happen at 13925 position behind the decimal point.

A number of your results have been crunched by very similar processors (same brand, same core), so one would expect the calculations to produce the same numbers.
Well, they don't produce the same numbers. In fact, the numbers produced by your overclocked cpu put the particle on a course into the wall of the facility near Geneva or on a course to Paris, Berlin, New York or perhaps even to the moon, instead of round and round in that ring burried in the Alpes, where the rest of the computers are sending it.

Put that computer back on stock speeds as soon as possible and keep very close watch on the results you return.

Already tested, no memory problems, and overclocking is just alittle, AMD xp2500+ 1833@2005MHz rock stable. So it is misterious.

you are still returning invalid results, so I suggest you drop it down to stock speeds and see how that works out when you get some more work from LHC

this is not about the credit mechanism or quorums.

he is returning invalid results and LHC is kind enough to grant partial credit to invalid results instead of chucking them out the window and grant 0 credit for them like most other projects do.

he should check his pc and make sure there are no defective or overclocked-beyond-the-borders parts.

i claim double, median is the half of it because my client claims more credits in other projects. but they granted me only the half of the median.

http://lhcathome.cern.ch/results.php?hostid=100692

new results arrived first or second to database and they granted me half the credit.

if we calculate median of the values my result doesn't affect this value.
don't matters if the max or min value are infinity or 0.

now i claim better the credit with truxoft callibrated client

http://boinc.truxoft.com/core-cal.htm

http://lhcathome.cern.ch/result.php?resultid=5454844 Validate state Invalid
http://lhcathome.cern.ch/result.php?resultid=5454797 Validate state Invalid
http://lhcathome.cern.ch/result.php?resultid=5454770 Validate state Invalid

If I were you I would have a good look at my computer with prime95 and memtest.
you are returning a lot of invalid results, are you overclocking?

Is there any chance the stats pages could be sorted in reverse chronological order? The test number mean nothing to me, but having the latest issued work units at the top of the list just seems to make more sense. Thanks.

would it be possible for the project to change the sort-order in which the results are displayed per user/computer from ID to date sent?
it get's very confusing when one has to search through result-pages 1,2,3,4,5,6,7,8,9,10,11 and 12 for the most recently processed results.

Whereabouts in Denmark?
Been there only once, for about a month, in the Arhus area.
I still enjoy the memories of waking up, going outside with a cup of coffee and seeing the sun rise over the golden grainfields near Lystrup. Just plain beautiful.

all results were returned well within the deadline, but are the last results to be returned.

if I am not mistaken, these are your statistics.

Borandi, if your "main" machine is running Windows, you really should have a look at BoincView
it may take a couple of minutes to set up, but it makes the thing a lot easier when you're running multiple "drones" on a network.
