During the last weekend (23-25 October) particles have once again entered the LHC after the one-year break that followed the incident of September 2008.

Friday afternoon a first beam of ions entered the LHC clockwise beam pipe through the TI2 transfer line. The beam was successfully guided through the ALICE detector until point 3 where it was dumped.

During the late evening on Friday, the first beam of protons also entered the LHC clockwise ring and travelled until point 3. In the afternoon of Saturday, protons travelled from the SPS through the TI8 transfer line and the LHCb experiment, until point 7 where they were dumped.

All settings and parameters showed a perfect functioning of the machine, which is preparing for its first circulating beam in the coming weeks.

Collisions in the LHC will be made hopefully in 3 or 4 weeks.

My small machine is waiting to grab the first tasks. Let\\\'s go for a collision!

Yeah i hope also we get a bunch loaded to Boinc. Most of them will go to the Grid.

This is very exciting. Ive been waiting to put some GFLOPS on this account and show what I can do. Einstein@home has received 100% of my CPU & GPU power, but I would like to show some work on the LHC too. Please keep us informed on this exciting news.

Particles in the LHC in no way relates to getting work here...

Yes but activity in the LHC is very exciting too. As data is produced they will eventually look to us for CPU power. After all, we are the super computer by our Boinc accounts and they will be recieving massive amounts of data to sort out which creates need. And need is where we come in!

Just to make an experiment. I have installed VirtualBox by SUN on my Linux box and then Solaris as a guest OS. The only app I could find in BOINC for Solaris is SETI. But it runs slower than on Linux host. I was thinking of a CERN VirtualMachine which was spoken of in a BOINC workshop, allowing a single CERN or LHC app running on all kinds of CPUs and OS. But VirtuaBox recognizes my dual core Opteron 1210 as a PentiumPro+mmx, so probably the app does not use all of the Opteron capabilies, as SSE3.

I don\'t think LHC@home is going to process any actual data. If the beams are not running as expected or they need to tune a mag or something perhaps, but all the science data is going to be dealt with on site.

No, not on site but on the Grid which has servers in Europe,America and Asia. They have already tested it with tons of fake data. This was reported on the CERN Courier.

NAGILUM would like to wish you all a HAPPY HALLOWEEN!
I believe these next few months will be exciting. The data runs on the GRID must be preparatory for the real stuff. I\'m sure they want to see how, \"We the virtually most powerful data crunching source.\", performs with fake data first and then send us the true data. VirtualBox by Sun sounds interesting too. But now I gotta go SCARE SOME KIDS!
