Re: [Condor-users] ENFORCE_CPU_AFFINITY and dynamic slots

[Dan Bradley <dan@xxxxxxxxxxxx>]

Bob,

You are right.  There is currently no good way to configure cpu affinity for dynamic slots, because SLOT<N>_CPU_AFFINITY isn't really appropriate for dynamic slots.  A job wrapper could be used to do it.

I talked recently with Greg about plans to provide a better solution.

Hi,
Am I right in thinking that the ENFORCE_CPU_AFFINITY setting currently only works with static slots, i.e. either the default case of a 1-core slot, or pinned to nominated cores for a multi-core slot? This is my understanding from reading section 3.3.13 of the 7.8 manual. Is there a way of defining using CPU affinity for dynamic slots? I'm only interested in the Linux case.
