I tried,
--map-by ppr:12:node --slot-list 0,2,4,6,8,10,12,14,16,18,20,22
--bind-to core -np 12
but it complains,
"Conflicting directives for binding policy are causing the policy
to be redefined:
New policy: socket
Prior policy: CORE
Please check that only one policy is defined.

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

Hi,
We've a machine as in the following picture. I'd like to run 12
MPI procs per node each bound to 1 core, but like shown in blue
dots in the pictures. I can use the following command to run 12
procs per node, but PE=1 makes all the 12 processes will run in
just 1 socket. PE=2 will make a process bind to 2 cores, which is
not what I want.
--map-by ppr:12:node:PE=1,SPAN
Thank you,
Saliya
