LHC has not permantently work, only if the scientists are require a new run, work will be issued. So it's no error and OK.

Also the actual Sixtrack application is only avaialable for Windows in the moment. But I have readen in the forums, that it's planed to releas a Linux application.
2) Message boards : Number crunching : Dotsch/UX 1.2 released (Message 22110)

Post:
At the last weekend I have released Dotsch/UX 1.2.

Dotsch/UX is a Linux distribution for BOINC which easily installs and boot from a USB stick, hard disk and from diskless clients and also has some interfaces to setup the diskless server and the clients automatically.

For more informations have a look at http://www.dotsch.de/Dotsch_UX

New features in 1.2 :
• Build in NVIDIA CUDA support, a additional tool to enable and check the NVIDIA CUDA support.
• Persistent Live CD mode for testing the distribution as Live CD and store the data on a USB stick/disk
• Automated and semiautomatic backup of the BOINC client data and some other OS data
• Included Ganglia for performance monitoring of the Dotsch/UX Grids
• Pre Installed BOINC client 6.10.17
• Removed a lot of unneeded packages in the x86 and x64 distribution
• A lot of bug fixes and enhancements

Special thanks to all the peoples which supported and helped to make the new distribution possible !

I, too, have an Mac (quad i7) that wants to participate. It can be done.

Please scroll a little bit a above. There is a solution with crossover to crunch on Intel Macs...

I guess that there would been released a MacOS application in the near time.

As I have written in the previos postings in this thread : The problem is, that diffrent compilers generate different results. But, if the project need 100% identical results from a WU it could be really problematic. That is the problem at LHC and some other Fortran based BOINC projects. The compiler which has LHC used is only available for Windows and Linux...

The only way to crunch is to using CrossOver - see my in previos posting in this thread.

Today I have released Dotsch/UX 1.1. Mayor changes are the availability of a 32 bit (i386) and 64 bit (x64) distribution, mixed i386 and x64 diskless client on one single diskless server, build in BOINC client 6.4.5 and bug fixes
 for the USB, hard disk, diskless server and diskless client Installation tools.

SIMAP and Superlink@technion has also Applications for Linux on the Power/PowerPC architecture. AIX will be supported by SIMAP and SETI@home.

This looks cool. I would d be interested to know if there is any performance increase when SuperSpeed USB 3.0 comes out at the latter end of the year.

Check this out:

With USB 3.0 the system would faster boot from the USB stick. But the crunching would not have any big benefits from USB3, because the most BOINC projects only writing a few data to the USB stick every several minutes.

In the SETI forums was a thread about routing problems. Looks like there was an issue with the http connect. For me the SETI and BOINC site works in the moment.

Post:
The LHC sixtrack applicaiton was compiled with a special fortran compiler which is only available for Linux and Windows. If other compilers would be used, it could produce differnt results.

The only was to crunch LHC on the Intel Mac is via CrossOver or Parallels. Parallels has much more overhead like with CrossOver...
A howto for seting up CrossOver for LHC is available on my hoemepage : http://www.dotsch.de/boinc/MacOS_Crossover_howto.html

Post:
First, there is no PPC science-application for LHC and there probably will never be one (see other threads).
Does LHC@home need good floating point performace ?
Same as on the other projects, too. The application must complete rewritten to get the full performance of the PS3 SPEs. Rewriting the source is a lot of work...
Also other problem, LHC uses a special Fortran compiler which is only available at Windows and Linux. Other compilers produce different resutls, but LHC needs identical results.
Rewriting the source isn\\\\\\\'t what i am asking for !

And as I have installed Fedora 9 on my PS3, it should be possible to install a Cross-compiler on your computer for your Fortran to produce PPC ( without SPE ! ) code for all PPC Linux platforms.

MfG, MEX

No. It it not posible to install a cross compiler. There is no crosscompiler for the compiler which CERN has used available for PPC or the PS3. The compiler which has CERN used is only available for Windows and Linux on x86.
Also the other problem is that there could be some hughe differences in the results by using a other hardware platform.
Without coderewriting the PS3 performs comparable as a G4/G5 Mac.

Hi there,
We still have some more tuning to do on the LHC and your help for that is appreciated.

We also have some other particle physics projects in the pipeline.

Great !!!!!!!!

Any timeline for the new project ?
Do you have some more details about the new project ?

Thanks, I'll try that. (But isn't Unix Unix? Why does Unix code have to be redone for another Unix?)

Over the very long history of Unix it was used by a lot of vendors on a lot of different hardware. So there are now a lot of different Unixes out there which are not binary compatible which each other...

MacOS is a Unix, too. But, that the application would ran on MacOS it must compiled for each Unix. LHC has used a very special compiler, which is only avialblable for Windows and Linux.

A other soultion to crunch LHC with a Intel Mac, is to use CrossOver. I have written a howto about this : http://www.dotsch.de/boinc/BOINC%20howtos.html
CrossOver emulates some things (API calls) from Windows. So it is posible to let some Windows science applications running on the Mac side by side the native MacOS BOINC client.
