I learnt that the problem can be solved in PBS, like this: #PBS -l nodes=n0000.nano:ppn=2+n0001.nano:ppn=2+n0002.nano:ppn=2+n0003.nano:ppn=2+n0148.nano:ppn=4+n0149.nano:ppn=4
Is there similar option doing this? Thanks! On Tue, Jul 9, 2013 at 6:40 PM, Pu ZHANG <[email protected]> wrote: > Dear Slurm users and developers, > > I have an issue concerning memory usage.
