I found
#SBATCH --ntasks-per-node=2
and now the job runs with NumNodes=1-1 NumCPUs=2 CPUs/Task=2
The docu on www.schedmd.com/slurmdocs/sbatch.html
shows
-n, --ntasks ......
Is this flag still working for job steps to run within the allocation
will launch a maximum of "number" tasks ? Doesn't look like it.
Thanks
Eva
