Try something like this instead: —map-by ppr:12:node —bind-to core —slot-list=0,2,4,6,8,…
You’ll have to play a bit with the core numbers in the slot-list to get the numbering right as I don’t know how your machine numbers them, and I can’t guarantee it will work - but it’s worth a shot. If it doesn’t, then I may have to add an option for such purposes Ralph > On Sep 12, 2015, at 7:39 PM, Saliya Ekanayake <esal...@gmail.com> wrote: > > Hi, > > We've a machine as in the following picture.
