You guys HAD a very nice web-site at one time. It was compliant with almost every standard. But nooooooooooo.

You had to scrap all that now did you now?

They had fixed some of the nonstandardness of the code, but when they did that they were already 1 year out of date from the official code. Recently LHC@Home upgraded its BOINC server code, probably having to undo their modifications.

Post:
LHC@Home never has work. Except when it does :) Seriously, it usually doesn\'t have work. We recently had a somewhat-big batch to process, first in a few months, but it\'s all processed by now (I think).

And availability of work is unlikely to have anything to do with cooling of the collider...

Thanks geo...

I am not sure I understand the system.

1. There is work to do.
2. I and my computer are waiting


1. There is LHC work to do.
2. Your computer is already full with other projects\' work.
3. Your computer thus doesn\'t ask for LHC work.

Does LHC@home need good floating point performace ?

The LHC@home app doesn\'t even support Mac, because there isn\'t any good Fortran compiler for OS X that can cope with sixtrack.

The PS3 does have good floating point performance. But it\'s way more than just a PPC. It\'s quite a different problem to get an application running fast on a PS3. The only projects that will support PS3 are those that are written from the beginning with Cell in mind.

8) Message boards : Number crunching : Maximum daily WU quota per CPU? (Message 19240)
Posted 15 Mar 2008 by PovAddict
Post:
Most folks seem to forget that the reduced quota was intentionally done to stop the constant noise about "fair distribution". If the quota was increased again, all the fast systems will consume work at a faster pace, eventually leading back to people complaining about things not being "fair", that they didn't get any work while others have a lot.

Complaints are like energy. Can't be destroyed, only converted to other types :)

Posted 10 Mar 2008 by PovAddict
Post:
I was not certain enough yesterday to contradict what povaddict has said, and I'm still not certain enough today due to not tracking down what is tickling my brain into thinking what I'm thinking, but I thought that there was a capability within the server-side aborts to do the abort unconditionally. The conditional "abort the task if it is not running" was the "user-friendly" option... I could be mistaken about this though. IIRC, it was said over on the SETI message boards and I think it was either by John Mcleod VII, Josef Segur, or Ingleside...

Yes. If the server notices the client has a workunit that was completely aborted by the admin, or a workunit that has already expired (user didn't return it on time) and even got validated from other results, it will send an "abort now, no matter if it's running or not".

However, *users* can't choose if they want an "abort even if running" instead of "abort if not started" in the common case that a workunit reaches quorum normally.

Posted 8 Mar 2008 by PovAddict
Post:
Yes. And because the server code is such an old version, the server can't ask clients to abort the unnecessary WUs. :-(


Otoh if a workunit is already in progress aborting it would be a waste, too.

The abort mechanism only aborts ready-to-run workunits. Running workunits only get aborted if there is no way for them to get credit (ie. if they are WAY too late).

Your serverstatus-page is also a bad joke. Your Upload/Download and Scheduler is disabled since a long time but units comes and goes?

It's not. The download/upload server is the same that hosts the forums etc. so if it was really disabled, the server status page wouldn't even load.

Posted 4 Mar 2008 by PovAddict
Post:
while there are more of the long 1m turn work units around, it made me wonder what sort of savepoints do the LHC wus have? none... every 1000 turns... every 10,000 turns? there's no search function on this message board, so sorry if it's been often mentioned before. I also fetched down an extra day of work in the buffer of the slower in my two rigs (they each take over a day on that one so you understand the savepoint question!)

My guess is that it can checkpoint on every turn, and since turns are so frequent, that will make it follow your preferences quite accurately (every 60 seconds by default).

No. The server is BRAND NEW (installed last year!)/quote]
The server hardware was installed last year. The software is 3 years old; ancient for BOINC standards.

You remember correctly. It's three years old. I once managed to post on the forums under the admin's account due to security holes, but they still haven't upgraded, nor accepted by offer to help them manually patch the holes.

Scheduler URL is on the main page inside an HTML comment. UMTS removes all HTML comments to "save bandwidth" (also recompresses JPEG images to make them look horrible).

@Admins: the solution is adding this to your <head>:

18) Message boards : Number crunching : Moving a WU from one machine to another? (Message 19013)
Posted 11 Feb 2008 by PovAddict
Post:
I have an older Pentium machine with 82 MB RAM that downloaded a WU and began processing it.

Originally, the time to completion was before the WU deadline. However, after running it for nearly 25 hours, achieving ~9% completion, the time to completion has increased (by an additional 8 hours!), and I fear it will not get done in time.

I would like to move it to my Pent. 4 laptop and was wondering if there is anything special I need to do?

I see the init_data.xml file contains a path to the files which are on a different drive in the older machine and I will edit this. Anything else?

Expiration is in four days.

Moving a single workunit to another machine? You would need to do lots of manual edits to client_state.xml; and I'd almost guarantee you'll screw up in the process. Moving the slot directory for that workunit is just the beginning.
