LHC@home

Obviously LHC@home still gets support from the user base otherwise these boards would be dead for a longtime already.

CPSS is down to less than 100 active volunteers and LHC@home support
has been dead for a year and it appears unlikely that IT will support it.

Yeah... I guess IR = 0 is better than IR=2, IR=3, and far better than that \"gosh awful\" IR=5...right?

This has nothing to do with the matter at hand. Bigmac clearly stated that \"...someone with real authority and responsibility...\" implying that he does not have the authority or responsability to go ahead with LHC@home on his own.

The exerpt from the email suggests that the Management Board is not convinced at all of the power of Boinc/LHC@home and prefers an in-house solution for the calculations. Or it might be that, with the thousands of scientists on the Collider project, it is simply a story of pet projects, power games, or complete ignorance on the topic of distributed computing.

It looks like quite a nice cluster: http://www.theregister.co.uk/2009/11/04/lhc_xeon_endorsement/

It seems very odd that CERN staff are heavily involved in adding VM capabilities to BOINC (see notes from the recent BOINC workshop), but LHC@home is left to rot.

Due to how sensitive the results are to very minor calculation differences / errors, LHC@home do not release their code for 3rd party compiling.

And yet, they rely on computers that are most likely overclocked and running Windows. I\\\'d trust PPC over i686 any day. Oh well. I didn\\\'t really expect it to be available anyways. My RS6000 will just have to stick with SETI@HOME.

Maybe some clues will turn up.

I'm confused. What am I missing here?

To abort redundant tasks manually one must first go to the LHC website and see which of his unstarted tasks have reached quorum then abort them in the manager. I don't see how that is just as easy as letting the software cancel the tasks for you. Furthermore, if you run a version that will comply with server requests to check in, for example every hour, then you can have redundant tasks canceled even while you are away at work or on vacation or whatever, assuming the server is configured to ask hosts to check in every hour.

Now, from your latest post I'm getting a different picture. I could be all wrong but it sounds like maybe you are trying to make a political statement by not upgrading.

• The installer blowing up and leaving BOINC in a non-functioning state that took multiple reinstalls of 5.8.16 to fully correct.
  
• No real need for any of the newer features.
  
• The bugs of the newer versions (apppears to be sloppy testing and/or poor judgement on "go / no go" decisions to me).
  

Only when this project started doing the cancels did I have a \"need\", but since I do not run this project very often, and considering that when I do I run it exclusively until I've cleared out the work, then I can manually abort tasks just as easily.

If hosts would contact the server more often then more redundant tasks would get canceled. The project managers can direct hosts to contact the server more frequently but they are not doing so.

Anyway, I noticed after posting that the status box listed the project as \\\"down\\\", but with work available. I didn\\\'t have the time to go back to clarify...

Actually the scheduler was down but everything else was running. There were several thousands results available but if the scheduler was down then the results won\\\'t get sent when hosts request work.

I recall you saying you tried to install 5.1.x but it did not go well, crashed or something. I vaguely recall one release in the early 5.x series which was quickly withdrawn because it caused a lot of grief. Perhaps you were unlucky enough to try that one.

I think LHC@home does not use HR. I have primarily Linux hosts. I have not received LHC work for quite some time but if I recall correctly they were almost always grouped with Windows hosts so heterogenous redundancy seems to be in effect here.

To clarify, if there was work available for other hosts, you will be told that there was work available for other platforms in the response message from the scheduler.

Close, except littleBouncer\\\'s hosts are Intel and AMD processors running on WinXP. A non-supported platform is not the issue here. The thread title is a tad misleading for the uninitiated.

littleBouncer's plan is not progress, it is regression to the old, slow, wasteful way.

Down=versioning isn\\\\\\\'t really an option. I have other work running (long jobs) and the change from Version 6.x.x back to Version 5.x.x will likely trash all the work already done. I have taken this route in the past and seen it happen before.

I went from 6.2.xx to 5.10.xx and it worked fine. It took a little more time but I didn\\\'t loose my cpdn @ 86% complete and 749hrs.

EDIT: Don\'t forget to set U\'r manager to SNOOZE before you start the downgrade!

:bump:

Viewing workunits still give a PHP error.

Also, the repair_forums script needs to be run to repair the escaping of ' and " marks...

I've noticed the same same problem, Viking69. You will also find slash marks in some posts. there are two workarounds necessary: copy and paste into a blank text editor (notepad) to see the entire post, and then use the edit feature to eliminate the slash marks.

Good luck,
Kibble

I checked in some code (in html/ops/repair_forums.php)
to change " to " and ' to ' in:
- forum posts
- forum thread titles
- profile text

I've run this on SETI@home and the BOINC message boards;
I recommend that you run it to make your message boards look nice.
