Hi Reuti,
I see now processes perfectly binding to cores after I applied your advice:
$ qconf -sconf
...
execd_params ENABLE_ADDGRP_KILL=TRUE ENABLE_BINDING=TRUE
Thanks a lot for your answer
Best Regards,
Edrisse

Dear Grid Engine developers and users,
I would like to bind processes to a sequence of cores or to a single
socket.
I tried to constrain my jobs to run on 8 cores within 1 socket :
qsub -S /bin/bash -N test -cwd -V -pe smp 8 -binding set striding:1:8 -q
1day.q job.sh
Unfortunately, I see processes jumping from cores to other cores during
the job.
I perhaps missed something, could you please advise me ?
Best Regards,
Edrisse
Notes : - I use Grid Engine 2011.1
- I set parallel environment on pe_slots
- My nodes architecture is 64 cores on 4 sockets :
did you enable binding in execd_params in SGE's configuration?
$ qconf -sconf
...
execd_params ENABLE_ADDGRP_KILL=TRUE ENABLE_BINDING=TRUE
Or do you mean that they are jumping inside the set of granted cores?
The allocation is also shown in /proc/<PID>/status
