Doesn\'t sound anything wrong with that.

The quorum is 3.
Once that\'s met credits are granted. Any tasks for the WU that have already started to be crunched by PCs will still be credited otherwise they\'ll be cancelled.

In the case of the one with 4 WUs receiving credit, obviously the one with the error won\'t get any but as the other 4 completed then they do.

The WUs are only cancelled by the server if they haven\'t started crunching on the PC


Ahhhh! Then a workaround would be to manually stop each work unit in a batch after a few seconds of work to ensure that it is considered as being crunched? Maybe hard for those with large numbers of puters spread about here and there, but fairly easy if one has only a few machines in a central location- and time to devote to their labor of love. LOL!


It\'s only worth doing that if you care about how many credits you have.
There\'s no point in doing that cause you\'d only be wasting CPU cycles on WUs that already have a valid results. You\'d be better off letting other projects use those CPU cycles.

All completed without errors, all claimed less credits than the other PCs, all resulted invalid.

I\\\'m running Ubuntu 64 and BOINC 6.3.14.

The CPU is OCed to 2.5Ghz (former 2Ghz) but it used to work fine.

Everything happened with the last batch of WU, which I received AFTER installation of BOINC 6.3.14.

Anyone else reports the same issue?


6.3.14 is a development version. I suggest going back to 6.2.15 and only upgrade with the next non-dev release. Non-dev releases have an even number after the 6.

I imagine it would just be a particle going around a big circle... unless the work unit errors out in which case I would expect a giant explosion :)


Perhaps they can\'t show it in case it generates a black-hole and swallows up the internet.

he Large Hadron Collider near Geneva will be out of action for at least two months, the European Organization for Nuclear Research (Cern) says.

Part of the giant physics experiment was turned off for the weekend while engineers probed a magnet failure.

But a Cern spokesman said damage to the £3.6bn ($6.6bn) particle accelerator was worse than anticipated.

The LHC is built to smash protons together at huge speeds, recreating conditions moments after the Big Bang.

Scientists hope it will shed light on fundamental questions in physics.

On Friday, a failure, known as a quench, caused around 100 of the LHC\'s super-cooled magnets to heat up by as much as 100C.

The fire brigade were called out after a tonne of liquid helium leaked into the tunnel at Cern, near Geneva.

Cern spokesman James Gillies said on Saturday that the sector that was damaged would have to be warmed up well above absolute zero so that repairs could be made.

While he said there was never any danger to the public, Mr Gillies admitted that the breakdown would be costly.

He said: \"A full investigation is still under way but the most likely cause seems to be a faulty electrical connection between two of the magnets which probably melted, leading to a mechanical failure.

\"We\'re investigating and we can\'t really say more than that now.

\"But we do know that we will have to warm the machine up, make the repair, cool it down, and that\'s what brings you to two months of downtime for the LHC.\"

I noticed theere was a result that was still in my results list from 2005.
I took a look at the WUID page and it showed there was still a user awaiting credit.

When I went to his page I found a whole bunch which hadn't been granted credit.

Any ideas??

I've stopped cleaning just to watch it. My estimated crunch time is 4 hours so I should start cleaning again then :D

I currently crunch for 14 projects including LHC on a single 1 CPU PC.

I managed to get a single WU......it's just the luck of the draw.

I would have got more and could've if I'd suspended all the other projects so only LHC was active, but I didn't.


Next 20
