Hi Michael, Sorry for the late response. Do you mean supplying --exclusive to the srun command? Or I have to do something else for partitions? Currently they use
srun -n 1 -c 6 --x11 -A monthly -p CAT --mem=32GB ./fluent.sh where fluent.sh is #!/bin/bash unset SLURM_GTIDS /state/partition1/ansys_inc/v140/fluent/bin/fluent Regards, Mahmood On Sat, Sep 1, 2018 at 7:45 PM Renfro, Michael <ren...@tntech.edu> wrote: > > Depending on the scale (what percent are Fluent users, how many nodes you > have), you could use exclusive mode on either a per-partition or per-job > basis. > > Here, my (currently few) Fluent users do all their GUI work off the cluster, > and just submit batch jobs using the generated case and data files. > > -- > Mike Renfro / HPC Systems Administrator, Information Technology Services > 931 372-3601 / Tennessee Tech University > > > On Sep 1, 2018, at 9:53 AM, Mahmood Naderan <mahmood...@gmail.com> wrote: > > > > Hi, > > I have found that when user A is running a fluent job (some 100% processes > > in top) and user B decides to run a fluent job for his own, the console > > window of fluent shows some messages that another fluent process is running > > and it can not set affinity.
