Hi all,
I'm trying to run parallel SMP job on my same 4-CPU execution host.
I've created my PE with qconf  -ap smp4 :

pe_name             smp4
slots                    4
user_lists            NONE
xuser_lists          NONE
start_proc_args  NONE
stop_proc_args  NONE
allocation_rule   $pe_slots
control_slaves    FALSE
job_is_first_task TRUE
urgency_slots     max

My queue configuration is:
qname                        calcolo
hostlist                        cluster
seq_no                        0
load_thresholds          np_load_avg=1.75
suspend_thresholds    NONE
nsuspend                   1
suspend_interval       00:05:00
priority                      0
min_cpu_interval      00:05:00
processors                4
qtype                        BATCH INTERACTIVE
ckpt_list                   NONE
pe_list                      make smp4
rerun                       FALSE
slots                         4
tmpdir                     /tmp
shell                        /bin/csh
prolog                     NONE
epilog                      NONE
...
...
...
default
...
...

When I try to submit with:
qsub -q calcolo -pe smp4 4 run_eng.sh
the job runs but on only one CPU instead of all CPU in my execution host.

qstat -f

Can somebody tell me where I'making an error?

Thanks
Luca
