for some reason this specific system ID: 10620917 throws alot of these errors

for example

6/10/2020 5:23:51 AM | LHC@home | Output file Theory_2390-1087325-16_0_r909140165_result for task Theory_2390-1087325-16_0 absent

I have re-installed and updated everything etc,

thanks for any suggestions

after all these years, its time to retire the Xeonster .
this was put together when the Xeon Quad cores first came out.
It has been under a Koolance liquid cooling system since I first turned it on...never over 115 degrees F.

...it has been dedicated to LHC for its entirety and been kept running in honour of our lost friend James Powers.

he would say now ...get rid of that old iron ...get more better shit.

Keep Crunching . o7

Comcast is the only option here.
That raises the arguement about local Utilities Districts and HOA's ,
net neutrality, access issues.

Until CenturyLink or Google drops fiber in this area, the other options are even more limited in speed and also data capped as well.

Oh to rage against the machine and greed of Comcast and this 1 tb data cap ..it will be the end of my Boinc farming hobby.

Being forced to pay an additional $55 a month to not be capped at a meager TB is not justifiable....As if network data is some rare resource like water or air.

The problem is the amount of data being moved by Boinc, running only Einstein and LHC w/ Virtualbox on my several machines.
This averages out to about 12 gigs of data sent/received per my 4 PC machines every 24 hours, in addition to the 50+ gb my Dell r810 was moving. Very quickly running past this arbitrary terabyte data cap.
Not including any other internet usage by the family.

Solutions such as fiber are not an option here.

*grumble grumble, sigh*

Thanks for the input Toby, but you are not understanding.
All of the other systems are able to cache 8-12 extra work units per the \"enough work for 1 days\" parameter.
This included the active 4 or 8 active wu\'s in process.

Only on this system it does not, this affects LHC and Einstein as well, so its not a LHC specific issue.

BTW: I do not sit there manually pressing the update button.

Its running under Ubuntu server.
The system manager shows 8 cores, and if there is work they all be running.
It just never cache\'s any extra wu\'s like my other system do.
Preferences are set to 32 cores..... 8]

......get a cache of wu\'s on my dual x5355 system.

The current parameters allow all of my other sytsems to cache (1 days worth) a couple of extra wu\'s, yet the x5355 never has any wu\'s cached.
So I end up with a core or two idle because the system
gets pushed back by the \"last attempt to recent\" error.

Surely this has something to do with the core count.


Great to have work !!

Posted 8 Feb 2008 by Perle
Post:
Brian when the project started...wu's would run about 2 - 5 hours.

Realise the hardware of the day of course, Amd socket 462 / 754 and 939 or a 940 Opteron.
Intel P4 socket 423 and 478.. 603/604 xeons....netburst and hyperthreading.
Lets not forget the venerable and rock solid P3 slotted and socket 370.
Now we are dual/quad core and multi proc (8 and 16 cores per box) etc.
Bus speeds are up, ram speeds etc, as well as the BOINC code and the Sixtrack code being optimised in various ways.

So my guess is that these new wu's are much more technical than those from a year or 2 ago, but proportional in relation to current hardware.

My dual xeon 3.0 ghz /800fsb wants 15 hours vs. a dual core 6700 at 4.5hours per wu.

Yes..encourage the waterboy..
Make him wear the bucket on his head and let him dig the ditch with the ladel.
Then.....flog him until moral improves.

It does appear that many of these zero credit results only required what appears to be very little cpu times.
At least those did not required 3hour or more to complete and earn minimal credit.

Nicely stated Ken.
The combined contribution from so many participants is whats important.

* I am having flashbacks of 'cool hand luke' *
Just like digging a ditch...Some of us have bigger and faster shovels but quite often it is the waterboy that is the most important part of the team.

Not to compare your efforts to that of the under-appreciated waterboy, but that those 'zeros' you have produced may be the most important piece of data that the scientists obtain.
I count a multitude of 0's withing my completed wu's.

sorry for having fun.....clearly having a 'tongue in cheek' sarcastic perspective is not diplomatic for some.

Best part about this slow progression of distribution is that even some of my slow and far aways systems are recording production, quite often these systems dont get much work due to their offline nature or lack of supervision.

Fun observation.
I use an older Compaq sp750 as a SCSI drive tester.
It is a dual P3 (slot 2) Xeon at 1000mhz fsb 133 L2 cache 256mb.
this system want 9 hours for a wu.

Yet my poweredege6850 with 4 Xeon MP 2.66 processors wants 15 hours.

so curious this is.

These are the are the longest wu's I can remember.
Even my fastest dual core want 4.5hrs for a wu.
The longest I remember even on my AMD x2 4400 (socket 939) were under 3 hours.
These are substantial, and I personally like it.

LHC is just my favourite project.
The work they are doing there....the possibilities of what they might discover.

The hope that they create a small black hole and George (the village idiot) Bush falls in and it is captured live for the world to see....Oops....did I say that out loud.
Just think...if would have used the trillions wasted destroying Iraq to support LHC, Einstein, Folding....ESPA.... NASA....the ELT in Chile.....etc etc.
I dont mean to drag american foreign policy and politics into such a wonderful human endeavor such as LHC. (steps down from soapbox)

Cheers to everyone....keep the crunch on!

Happy new year to all !

The farm has evolved as usual.
The most notable addition is a Poweredge 6850 running quad 2.66 MP xeons.
These are dual core hyperthreading.....so 16 threads.
Its not as fast as you would think....but it does have solid production.
The reality.....a new 5400 series quad core Xeon could probably outrun it.

Did Santa bring anyone else something shiny and new ?
