Post:
Is it not possible to split data as EAH did?They have huge amount of data from all detectors,which they split into number of small batches.

Or required set of data for each WU is still too big?(Like it has to have data from all instruments used for collecting data)

I think that since there are going to be many runs/collisions,that each one might not to be so data-intesive,so each WU could be then one/two runs.

Can I have one too? It would give me
somewhere to keep my little boys toys.
I can see it now, \\\\\\\" kai, how many times
have I told you to put your ben 10 and
starwars toys into the black hole when
you\\\\\\\'ve finished with them\\\\\\\"? \\\\\\\"I nearly
broke my neck\\\\\\\"!

My boys have already got a black hole in their room. I think all the socks go there.

I did give them one of these natty GridPP Magic Cubes, but after i nearly sliced my foot open on it I reclaimed it as far too good for them and now keep it by my computer to fiddle with.


I already have at least two of black holes...(one in house and one in the garden...)

Since the server upgrade, the first column of the forum (that indicates whether the thread is sticky) does not size properly in IE7 (it is fine in Opera 9.51).
In IE7 and Opera 9.51 the input text box when posting does not correctly align (it spans 1 column instead of 2) and it doesn't properly wrap text (I had to copy and paste this from Notepad to see what I was typing!).

All table colums resizing is broken.Confirmed with IE8 beta1 in normal mode.
And textbox size is wrong and second partis not even visible,so one is typing blind. :-(

Just curious to know how long it takes to post credit for completed W/U? I am waiting on about 40 or so W/U to be credited since back in December. I AM around here for the science but at some point we all like to know how we progress in our efforts.


Are not those with "nearly" zero credit?We all here are waiting...

a) 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?


Sure.How much space do you need?


£150,000

That is supposed to be WHAT???Price of HDD or just money ,project is missing...

I would be willing to bet that if they did a port of their analysis program to BOINC we could do as well as the super computers they have lined up to do their data .

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.

Well, there are quite a few of us with both the bandwidth and larger than average computers ...


I second that. The size of the downloads shouldn't cause me a bandwith problem, most of my systems have plenty of disk space (and 500 GB disks are the only $100 or so these days). Admittedly, I have several systems running XP Pro, which therefore have memory limitations. The only reason most of them are running a Windows OS at all is that proteins@home doesn't have a Linux app. Give me a steady supply of LHC work, and I'll buy memory, install Linux, and abandon proteins@home.

Maybe you should create a second project for the analysis work (with strong warnings about the kind of machines required to run it). I'd be attracted to such a project, and maybe other people with serious hardware would.



I third that!, lol
A high bandwidth project, even if it took days or a couple weeks to crunch a single WU would be doable and if need be could parallel multiple CPU's if it's supported to crunch it faster. There are many of us that are flexible enough with our hardware that those numbers are not that big of a deal really. If you set up the requirements, people will crunch it. You'd be surprised how many people could attach a 10,20, or even 50 gigaflop cluster out of old junk if you asked them to. In fact I think that would be a very popular project, because people would look at it more as "elite credits" and build up to crunch it.


Big computers with huge HDD and Ram are not problem for me...(Before crash I had fully working 1TB partition + 0.5TB Partition for backup)

And I have access to academic network with 100Mbit/s line (ethernet) :-)

So I fourth that...

The bulk of my BOINC time dedicated to bio-projects is now split between SIMAP and POEM@home (who are working on the same stuff as Rosetta, but seem to be a bit more involved with their users, though this could be just the first flush of interaction that most projects manage).

I kinda like the idea of SIMAP, though both it and LHC with the sporadic work availability causes me a great deal of annoyance in that I prefer "physics" type research (given my druthers) and this and EAH are the only two fully oriented in that direction.

We have the several that are pure math (PrimeGrid, Sztaki, ABC), the odd ball ones ... CPDN which does not fit many molds, and then the rest seem to be biological.

And don't drag me into the Beta projects that are doing wonderful things... I'd rather not, thank you very much ...

And I suspect that the involvement will dry up as it did in Rosetta ... for the first couple months there were daily posts on almost all boards by the project and then ...

Anyway, no need to get me started ...


Well,one could almost say that most of projects are in sense betas... :-)
(And I like betas,never had problems with any)

Post:
I was wondering why I see numerous questions by people helping LHC@home that are ignored. Does the LHC@home staff consist of just two people? As a professional astronomer I can truely say that if my students or those who are helping in a research project didn't feel they could come up to me freely and ask a question pertaining to astronomy then they wouldn't be inspired to have astronomy or atro-physics as a major would they?


I would say that at least for one year for sure only two people are in team.(at least active...)

No, its not quite true, Dagorath only argues if there is some thing blatantly stupid that even a blind person can see :) the question that should be asked is, why do Alex or Neasan not come up with a plausible counter argument as to why they need an IR of 5 :( Alex and Neasan are the ones in fact prolonging the argument by not doing so. :) if seen in perspective the WU's where the protons crash on start up :) IR of 5 is silly. so why not further process the worth while WU's if required and the duds can be put in the dust bin on a IR of 2? as a start may save a few CPU cycles.
Dagorath keep the tone ;) down but fight you battles ;)

Masud.


Well Neason or Alex???


Maybe I remember incorrectly,but they already answered this in this thread.

Thats to bad, but what can you do about it .....

Resign yourself to the fact or vote with your feet and crunch something else.

Why resigning?It is at most problem for database not crunchers...
And maybe they want to keep them for some reason in BOINC database and not somewhere else.
Credits are in factnull so or so and won't make any difference to your account.

What is seen with IE7 is called "quirk mode".It is backward compability with IE6 and older.In IE6 MS missunderstood CSS specification for width and wrongly computed size.In IE7 it has been corrected for "standard mode",but not for "quirk".

Since DOCTYPE is missing at the start of pages,IE7 assumes it should use quirk mode instead of standard.
