Hi Reuti,
Thanks for the two options and sorry for the late answer,
I just have a last question : after submitting a job, one or more
socket(s) will be used. At this point, is it possible to extract from
SGE the socket number(s) which are used by the job ?
Best Regards,
Edrisse

We have a set of machines with 4 sockets of 8 cores for each machine
(so, 32 cores per machine).
We usually ask 8 cores for most of our jobs.
We would like to bind each job submitted to any free socket available.
What you can do in SGE is to define 4 queues per host, with a number as suffix
which reflects the to be used socket. With this number you have to do the
binding on your own (but it could be put in a queue starter_method, as during
the start of the job the number of the socket is fixed already).
So, my question is : Is there a way for Grid Engine to see a set of
machines not as machines with cores, but as a set of sockets ?
I mean, is it possible to configure Grid Engine so that for each
submitted job it goes to a free socket unit instead of set of 8 free cores ?
In UGE they introduced RSMAP for this.

Notes: - I'm using GE2011.1
- I know it's possible to bind jobs to cores with -binding
striding option in qsub. But the architecture of our machines is quite
complex. So, we have difficulties in finding the right core combination
to bind exclusively & automatically each job on free single sockets.
