To extend this a little bit: If you want to keep a dedicated CPU and its cores out of the business: you can try to set an affinity mask on these CPUs before you start the sge_execd. I would expect that all forks of this process will inherit this. But: you have to do the opposite for the processes running outside of SGE on this machine, to use only the other CPU. Nevertheless this might lead to some penalty regarding memory access in case memory from the unassigned CPU was used and processes can't be shifted thereto. -- Reuti PS: What about the free VMware vSphere version and making two machines out of it which are clearly separated regarding cores and memory? > Hope this will help. > > Regards, > > > > > On Wed, Sep 4, 2013 at 5:43 PM, Jacques Foucry > <[email protected]> wrote: > Hello folks, > > I have a special question for specialist. > > Imagine a new computer newly added into the grid.
