But after about one year it turned out to be a waste of time and was more like being a facebook member.

Hi all,

I have one long WU left, it's still waiting for a second reply.

http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2525806

Let's see how many credits it gets.

Michael


That one validated and 1,319.86 credits were issued for 172,315.40 CPU s; my result is the canonical result. Too lazy to do the maths.

I am really excited to be doing workunits now for the largest scientific instrument on the planet. I am trying to reconfigure the machines I have to get more work out of them. Keep up the good work. I am sure I have no idea how difficult it can be to operate such a machine. I hope in the near future to upgrade my computing capabilities to be able to do more of this important work. Try to ignore impatient people and realise there are some of us out here that appreciate your efforts.

Yes, we *never* had that much available WUs. 450+K is way more than in the good old days of 2004. As far as I remember 100K was the average.

i could care less about the credits i earn, and would simply be content knowing that my machines are contributing to the science behind the project.


I concur.

Although giving credits according to sixtrack's internal accounting (thinking of #completed turns) would be nice.

10) Message boards : Number crunching : Invite old users again? (Message 24539)
Posted 8 Aug 2012 by Michael Karlinsky
Post:
Hi,

what about sending a mass email to the registered users in the database (only email the users who have agreed to receive emails of course ;-) and tell them that LHC is up and running again? Maybe right now it´s a bit too early but I think you should consider this.

When looking at the server status there are around 100k registered users but currently only ~ 10% of them with recent credits so there´s a huge potential for increasing your computing power :-)

Keep up the great work.


Hi Tom,

that *might* work, but I doubt it. 10% active users is the BOINC avarage.

See this graph.

Thanks Erik for informing me. I understand that there are too many contributers.

I have seen the press conference wensday. Its fantastic. I will contineu wit my help. Its very important what you do on CERN. I have visit several time's the Prevessin-site and the Geneve-site whene my brother Jos Kuipers was working there. I hope
I will be able to visit it one's again.

R. Kuipers, Holland


Press conference was amazing -- although I did understand next to nothing -- the moment where the slide w/ "5 sigma" was shown and the audience started applauding furiously was worth watching!

And thinking of the fact that we helped building the LHC -- if only by calculating some beam trajectories -- that's just awsome!

If you're not receiving work it's probably because the only tasks left in the queue are resends (tasks that failed to verify or returned late).


Guess, or verified info?

Hmmmm - the server status shows 18,284 ready to send,
but I'm not getting any.

I guess I'll wait until the other three are done, and check again.



Same here :(

No explanation in sched_reply_lhcathomeclassic.cern.ch_sixtrack.xml, just "No work sent".

Both results returned are not equal (or marked as such by the validator). This is (usually) normal behaviour, if it does not happen often.

But here? Maybe some admin will have a look at it?

I got a few v530.03 WU when I attached to LHC 1.0. Now I get the messages
06/09/2011 10:51:57 PM | LHC@home 1.0 | Sending scheduler request: To fetch work.
06/09/2011 10:51:57 PM | LHC@home 1.0 | Requesting new tasks for CPU
06/09/2011 10:52:02 PM | LHC@home 1.0 | Scheduler request completed: got 0 new tasks
06/09/2011 10:52:02 PM | LHC@home 1.0 | (Project has no jobs available)

but then for some reason my account shows
Maximum daily WU quota per CPU 0/day

I didn't think it was possible to go below a quota of 1. It must be a bug in the system.


See thread "below"

This is a bug.

Michael

PS: Maybe a mod can rename one of the thread titles accordingly?
