Dagorath --

Is it possible that the fourth and fifth crunchers are not continuously attached to the Internet? Perhaps they connect only once a day, or maybe even once every other day, because they utilize a dial-up connection.

I grant you, that the method being used may not be the most efficient, but it does work (most of the time).

Like you, I do not get all the WUs that I can handle, but I do get some, and remember, I FREELY DONATE MY TIME TO THIS PROJECT (among others). Last time I looked, there is nobody holding a revolver to my head, and forcing me to make time available on my machines. I am here BY MY OWN CHOICE. If I feel at any time, that my services are being mis-used, there\'s a button on the PROJECTS page of BOINC called DETACH ... I understand it works very well




If I've lived this long, I've gotta be that old

1/ no money:

it could actually save money, by not letting it on the grid you save computing power.

2/ subsets wu\'s : why can\'t they be split up, 10 MB peaces.


3/ person to do so, see point 1.



\"To get money you have too spend money.\"

I got several of those WUs recently. And since the machine that I\'ve made available currently to LHC is a slower box, I wasn\'t one of the first to complete a WU. My machine checks in with LHC@HOME frequently, and so got the request from the server to cancel the processing of that WU.

So, even though some of the \"extra\" time wasn\'t used, the project was nice enough to let me know it didn\'t need it. That\'s better than letting me finish the whole WU and then not give me credit. It\'s a good balance.

I was searching around on the net and I found a Cern Press Release Witch says they are processing 250,000 jobs a day. I just wish we had big enough processes to help. What ever work this project gives me i\'m glad to crunch, I\'ve had 3 work units today so far.

Have A Crunching Good day

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.

I don\'t think it is a technical problem but a mentality problem. Being a (retired) physicist myself, I know they don\'t want, as a class, to give their precious data to the populace. But they shall have to do it. See David Anderson\'s article posted on the BOINC home page.

Wrong. It\\\'s a technical problem. We simply don\\\'t have the bandwidth. They have already explained that. When is it going to sink in?


My ADSL has 7 Mbit/s, but big cities in Italy reach 20 Mbit/s. Fastweb is offering fiber to the home in selected cities. Once fiber is installed there is no limit to bandwidth.

Apparently the IT people at CERN think that\\\\\\\'s not enough. Do you know something they don\\\\\\\'t know?

Wonderful! When enough BOINCer get fibre to their homes and a GPU in their box CERN might change their policy. The reality of today\\\\\\\'s world is that CERN thinks our resources are inadquate and they are probably right. So why not crunch some other worthy projects along with the LHC tasks you get and be happy about it.


I am crunching Einstein@home, QMC@home, climateprediction.net, CPDN Beta and SETI@home on my AMD Opteron 1210 running Linux at 1.8 GHz. Cheers.

It\\\'s a shame we can\\\'t crunch actual LHC data, the ~ 2Tflops that the user contribute isn\\\'t bad, if everyone gave 1Gb of space there would eb a few Tb of storage.
