1) Message boards : Cafe LHC : National Geographic Article (Message 19141) Posted 2 Mar 2008 by tenfiveoh Post: National Geographic ran a decent article this month on the LHC. It's not very technical, but very positive. There are some nice photos particularly of the ATLAS collector. You check it out also at ngm.com
2) Questions and Answers : Sixtrack : Download and computation errors on 4.67 (Message 7223) Posted 26 Apr 2005 by tenfiveoh Post: Ever since updating to sixtrack 4.67 (Windows) CC 4.25. I've not had a single successful work unit. Half fail during download & the rest when starting computation. Here's an example of the error reported by BOINC: 4/26/2005 4:26:37 PM\|LHC@home\|Finished download of v64lhc.D1-D2-MQonly-inj-no-skew-55s14_16524.2308_1_sixvf_19502.zip 4/26/2005 4:26:37 PM\|LHC@home\|Throughput 1675 bytes/sec 4/26/2005 4:26:37 PM\|Einstein@Home\|Pausing result H1_1179.4__1179.9_0.1_T05_Run2_0 (removed from memory) 4/26/2005 4:26:37 PM\|LHC@home\|CreateProcess() failed - The process cannot access the file because it is being used by another process.

3) Questions and Answers : Windows : Locks up my machine (Message 6509) Posted 8 Mar 2005 by tenfiveoh Post: For about a week or so now LHC has been locking up my machine at least daily. I am running CC 4.19, LHC@ 4.64, on win XP home SP1. I run it in the background, no screensaver. My machine will complete freeze still displaying the desktop. The only way to restart is to unplug the whole box.
4) Questions and Answers : Sixtrack : New sixtrack 4.63 is chrashing my WinDOOF ME ... (Message 6062) Posted 24 Feb 2005 by tenfiveoh Post: Sixtrack v4.64 is available. If you reset the project it should dump your 4.63 work units and then download 4.64.
5) Questions and Answers : Windows : Not Updating (Message 5978) Posted 23 Feb 2005 by tenfiveoh Post: I received new work units today, but it's still running sixtrack v4.63. BOINC didn't download v4.64
6) Message boards : Number crunching : LHC official status report (Message 5068) Posted 10 Nov 2004 by tenfiveoh Post: > I hope other concrete science project (perhaps space engineering projects or > stuff like that) will one day use this technology. > > When the accelerator will be complete, at least I'll be able to say "hey, > It's a little bit thanks to me you know" > > Keep up the good work guys ! > > As for my fellow crunchers, keep crunching ! > > I make a toast : > > For Science ! > Finally, someone with the right perspective. If you read enough posts on enough project websites it seems all anyone talks about is credit and every little server hiccup. And by "talk" I really mean complain. The point of participating in a DC project is to offer help to the researchers. It's more tangible than just donating money. A chance for the little guy to dip his hand in science. The end result is what's important. Most people run more than one project so you as a user should never have down time. And BTW this project keeps in touch with it's participants much better than some of the others out there.

7) Questions and Answers : Sixtrack : Changes in Sixtrack 4.47 (Message 4444) Posted 27 Oct 2004 by tenfiveoh Post: > And it seems to be slower than the previuos version :-\| > > I am getting the exact same run times as before.
8) Questions and Answers : Sixtrack : error in 4.47 scheduler_reply (Message 4442) Posted 27 Oct 2004 by tenfiveoh Post: Basically means the server's down & the error message it sends is corrupted and can't be read by the client.
9) Message boards : Number crunching : What's up with long winded WU crunches....?

A tunescan wu at 1,000,000 turns takes my machine 7-8 hrs where the others average 36 minutes.
10) Message boards : LHC@home Science : Cern site lists many Distributed Computing projects. (Message 4082) Posted 22 Oct 2004 by tenfiveoh Post: This site is probably the best at listing and providing updates for current & upcoming projects. www.aspenleaf.com/distributed/distrib-projects.html
11) Message boards : Number crunching : What is the difference between proeight/pronine/protwelve WUs? (Message 4081) Posted 22 Oct 2004 by tenfiveoh Post: From what I gather, there shouldn't be any noticeable difference between the types of work units to us other than how many loops the beam makes. The folks creating the work units label them to identify for themselves which type of run, what parameters are changed, etc. A similar question was posed in this thread http://lhcathome.cern.ch/forum_thread.php?id=531
12) Message boards : Number crunching : LHC has Setiates ... !!! (Message 3979) Posted 18 Oct 2004 by tenfiveoh Post: During LHC downtimes here's another particle accelerator design project you can try out at http://stephenbrooks.org/muon1/ There's no downtime, no work units to download, requires basically no babysitting, but still leaves room for plenty of manual parameter manipulation for those who like to tweek.
