hello all,
i got trouble to confgure a queue on SGE 6.2u5 (linux)
I have two machines amd64, with this topology: SCCSCC so the total of cores is
8.
<snip>
and the PE is defined by:
qconf -sp mpi_labo
pe_name mpi_labo
slots 8
user_lists NONE
xuser_lists NONE
start_proc_args /bin/true
stop_proc_args /bin/true
allocation_rule $pe_slots
$pe_slots means that all slots must be allocated on one and the same machine.
You can try $round_robin or $fill_up (man sge_pe) to get slots from different
machine.
But: Using threads (like Open MP) needs an SMP machine. So, running 8 threads
in SMP isn't possible in your configuration as you have only 4 per machine. You
will need for example an MPI library to compute across machines.
exactly what i missed! very thanks!
