LHC@home

Hi, I have an amd64-bit processor running a 64bit gentoo kernel/system. Everything works fine except for boinc, i get this message:

Thu 29 Sep 2005 05:38:47 PM JST|LHC@home|Message from server: platform 'x86_64-pc-linux-gnu' not found

is there support for 64bit linux? I'm assuming that's what this error is about?

The problem is that we do not have a version of sixtrack that has been compiled for 64 bit.

Are you planning to develop a 64 bit version ? I also have an x86_64 processor and I'd be glad to participate.

I third this motion for a 64-bit version of LHC@Home. I'll try the same hack I've used with Einstein@home (made its 32-bit version work), and will post the results here.

Running on an AMD64 system

First, go to the Boinc project directory. On a Gentoo system, that is:

# cd /var/lib/boinc/projects

Create a directory for lhc@home if it doesn't exist:

# mkdir -p lhcathome.cern.ch

Enter the newly-created directory:

# cd lhcathome.cern.ch

Get the 32-bit client:

# wget http://lhcathome.cern.ch/download/sixtrack_4.66_i686-pc-linux-gnu

Create a app_info.xml file:

# emacs app_info.xml

Enter the following on the file:

<app_info>
<app>
<name>sixtrack</name>
</app>
<file_info>
<name>sixtrack_4.66_i686-pc-linux-gnu</name>
<executable/>
</file_info>
<app_version>
<app_name>sixtrack</app_name>
<version_num>440</version_num>
<file_ref>
<file_name>sixtrack_4.66_i686-pc-linux-gnu</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>


Save and exit. Then, restart Boinc.

Downloading the client should be easier, maybe a fallback option from 64 bits to 32 bits.

Hello,

I tried to follow the posted steps, but the download fails with error 403: forbidden.

Is there any way to get the 32Bit-App downloaded?

Greetings

Is there any way to get the 32Bit-App downloaded?

Try this: http://lhcathome.cern.ch/lhcathome/download/sixtrack_4.66_i686-pc-linux-gnu

It's good idea to send 32-bit client to 64-bit Linux users, like many other project do. It's worse than real 64-bit application, but it will at least let guys with 64-bit linuxes to run LHC@home.
