Same problem here. This is my first LHC@Home unit so I don\\\'t have any \\\"it worked before\\\" to benchmark against. As I\\\'m writing this the work unit has been at 100% for 1hr 20mins and does not seem to be using any CPU usage on the WindowsXP task manager. However nor is it completing the task and other BOINC projects are waiting for it to finish.

I suppose if I has multiple processors I might not have even noticed this.

Are you using a 6.2.x client? A number of people have had this problem with the version 6 clients. The answer seems to be to downgrade back to 5.10.45.

Hope this helps

22) Message boards : Number crunching : Actual LHC data to crunch? (Message 20291)
Posted 12 Sep 2008 by MSeery
Post:
So essentially what MSeery is saying is that this project is entirely useless and will never get work.

I have been subscribed to this \"project\" for an eternity and never got any work from it. If this project has nothing to do it serves no function and should be shut down. I think BOINC users has much more important things to do then waiting for never arriving work. And the most irritating thing about the LHC@Home is that there is no real information that this project is just a wall of air. you have to poke around in the forums before you get the message. I suggest this project gets something to to or disappear into a black hole.

That is not what I\'m saying. The original question was about if we would be helping with analysing the data produced by the LHC, which we won\'t be. This project is about helping the scientists with the configurations for the beam, which in my opinion is an important and worthwhile function. There is also ongoing work being created for this. They are also looking at bring other physics projects into LHC@Home which hopefully will extend the usefulness of this project.

Hope this helps clarify matters.

Post:
I'm a bit confused here. I upgraded to 6.2.18 since I was having some vista issues with 5.x, and as we speak it seems to be happily churning on LHC WU's (I've even completed a few and gotten credits for them). What exactly is the problem with 6.2.x?

Some people have been having problems as reported here. If 6.2.x is working okay for you, then I wouldn't worry about it.

Hope this helps

24) Questions and Answers : Sixtrack : server error: can't attach shared memory (Message 20198)

Post:
Today I joined LHCatHOME . But I\\\'m getting following error.

Server Message: Can\\\'t attach shared memory.
Why?
When it will be solved

There is a problem with the server at the moment, which is why you are getting the message. It will be solved when Alex or Neasan (the project administrators) fix it basically. They are based in London, so the working day starts about now, so I would have thought within the next few hours (unless they are at CERN for the switch on).

Post:
When, if ever, will LHC@home be crunching actual LHC data in WUs?

In short, we won\'t be. The actual messages are over several threads, one is here.

Snippets for a quick read are below

Not a chance, a single dataset which a machine needs would be at least 1 gigabyte of data and your machine would have to download that before it could do anything else. We are TRYING to find something from the analysis of real data that will port but the big four have told us that the code is too, lets say, verbose.

and
We have a second project it\'s called the Grid. The LHC\'s computing needs are being fulfilled by that IF we can get something ported to BOINC we will but I reiterate we have no money. Also it\'s not just the download are you all willing to have large, hard drives, massive broadband connections and run only Scientific Linux (CERN edition) and not use your machines for anything else?

and
However this would require a person to port the software from the current Grid setup to BOINC and for the Grid software to be actually portable. Not only do we not have this person (see the money issue above) we have also been told that there is no way the applications the Grid runs are lightweight enough to be ported to BOINC. We keep prodding and asking about simulation applications/other experiments etc but nothing so far.


Hope this helps

Post:
Hey,

Well pending the black hole about to be .. kidding.

I thought i would help out a bit but i get no workload? Yet there seem to be about 260 pending projects on the server?

The workunits are actually in progress, meaning that they have been sent to a computer, but have not yet been returned. To see if work is available to be sent to your PC, you need to check the top line, which currently states Out of work.

Posted 5 Sep 2008 by MSeery
Post:
Hi,

I noticed that many among the latest WUs my hosts processed lasted no more than 10 seconds (mostly much below that).

Is that normal?

Bye

darkpella

Yes this is normal. The very short workunits are ones where the parameters make the beam unstable and it crashes into the LHC.

Post:
If I set LHC at a low priority, when there
is no work for LHC, does my other project run
at 100% or at the reduced proportion?

Your other project will run at 100%.
Also, does this affect how much work I get?

To a degree. BOINC will try to ensure that each project gets the time that it should for the resource share assigned to it. If a project has a lower resource share than it gets less time, therefore less work. It is a bit more complicated with LHC, as time is almost always owed to LHC from other projects as the work is intermittent.
Lastly is it 10 per user or 10 per computer?
I've kept my slower machines off LHC< but
since the WUs are small, 10 per machine
won't eat into my other crunching too much.
Advice will be appreciated.
Thanks. - KEEP ON CRUNCHING.

It is 10 per CPU core as I understand it.

Hope this helps.

I'm running Mac OS X 10.4 (tiger), and have heard that OS X is basically the same as UNIX. My BOINC client, however, has recieved no work, even though it should. Any ideas?

There is no MacOS application on LHC@Home, only Linux and Windows.

Post:
I understand there's still no or little work, right?

Correct.

As the turn-up of the LHC is imminent now, are there any plans to use the help of the LHC@Home Community for doing the real science on LHC?

No. As previously posted by the admin (these quotes have been snipped, but you get the general idea).
We have a second project it's called the Grid. The LHC's computing needs are being fulfilled by that IF we can get something ported to BOINC we will but I reiterate we have no money. Also it's not just the download are you all willing to have large, hard drives, massive broadband connections and run only Scientific Linux (CERN edition) and not use your machines for anything else?

I have two accounts. Both have the same name and same password. One has my current and correct email address, the other has my old email address. I have tried several methods to get these two merged but nothing seems to work. Is it possible and how would I go about it? Thanks

It isn't possible to merge accounts, only computers within the same account.

Sorry

35) Message boards : Number crunching : Some work unit results are missing (Message 19676)
Posted 26 May 2008 by MSeery
Post:
Why are work units and results disappearing?

Workunits are removed from the master database when all five results are returned. This ensures that the database remains as small as possible so that performance doesn't suffer. The results are still available to the project scientists.

Post:
I want to reinstall LHC@home (after I lost everything due to a lightning strike), but the BOINC Manager "attach to a new project" button requires me to enter an "account key"

Q. How do I get the account key resent?

Ken

You can have the account key sent to the email address you signed up with from this page

http://lhcathome.cern.ch/lhcathome/get_passwd.php

It also sounds like you have an older client. The current client only requires an email address and a password to sign up to a project that you already have a account at. You can download the latest client from here

Posted 18 Dec 2007 by MSeery

The results I've had a quick look at appear normal, all your fellow crunchers returned them with a very short run time as well. This is normally caused by the magnet configuration being simulated being unstable and the beam failing as a result.
