LHC@home

Can we assign an app_config, for 8 cores, such as:

<app>
<name>sixtrack</name>
<max_concurrent>2</max_concurrent>
<fraction_done_exact/>
</app>
<app_version>
<app_name>sixtrack</app_name>
<avg_ncpus>4</avg_ncpus>
<cmdline>-t4</cmdline>
</app_version>


If not, how much trouble is the implementation of multi-threading the WU?

Hello,
Why not to use LHC@HOME preferences ?
You can select amount of CPU !
If you want to run 4CPU on one host and 8CPU on a other host,
add a separate computer location with preferences you want (CPU/GPU/application/ressources).

That's running 8 single core WU at once; not running one 8 thread WU and not what I'm looking for.

Hi,

SixTrack is not a multi threaded application, and due to the nature of the simulations we run on SixTrack, there is no real need for parallelising it.

A bit OT, but ...

Thanks Veronica.
It's very nice to see that someone from the core team (or close to it?) answers volunteer's questions.

Thanks!

There are currently six of us maintaining and developing the code on a regular basis. We're hoping SixTrack 5 can soon go into production on BOINC.

Thanks for the response and your work on the project.
