[Gate-users] GATE IN MULTICORE PROCESSOR STAND ALONE WORKSTATION

[Copernicus]

yes sure the solution that i have send out was done for cluster mode, just
give other option to do the same it works too in a computer multicore but
you need N times memory than the single simulation needs.

Togheter with that i dont know if gatemultithread touch the topic about the
parallel random number generation. i need to re-introduce myselft to this
looks like is a lot better than when i see the multithread version of Geant4

Saludos
