[Gate-users] Running gate on multiple CPUs and SPECTbenchmark

[Samuel BURG]

Hi,
   
  I've recently try to do something similar : running OpenGate on Linux x86_64 on a Intel Core 2 Duo (and on a Condor Cluster, but this is an other story), it only use one core, and while trying to use the 2 cores, it crash (lanching 2 instances of Gate).
  If you find a way to use more than one core per computer (without using virtualisation) thanks to get me update.
   
  Best regards,

  I've finally got Gate installed and running, and it's running the PET
benchmark.

I'm planning to simulate SPECT, so I tried to run the SPECT benchmark,
but it crashed with the following error:
"Illegal parameter (0) "
Any ideas? 

I notice that it's only running on one core (We have 2x Opteron 2216
dual core cpus).
Is there a switch or simple way to use all 4 cpus, or do I need to use
the cluster mode I'm reading about in the user manual?
