Hi all, I'm struggling to get an heterogeneous job to run... The SLURM version installed on the cluster is 17.11.12
Here are the SBATCH file parameters of the job : ================================================================================ #!/bin/bash #SBATCH --threads-per-core=1 #SBATCH --ntasks=1 #SBATCH --cpus-per-task=1 #SBATCH --mem-per-cpu=8G # #SBATCH packjob # #SBATCH --threads-per-core=1 #SBATCH --cpus-per-task=4 #SBATCH --mem-per-cpu=2G #SBATCH --nodes=2 #SBATCH --ntasks-per-node=2 #SBATCH --gres=gpu:2 #SBATCH --gres-flags=enforce-binding ================================================================================ Now the SRUN commands that I tried in the SBATCH file: 1) srun --mpi=pmix myapp => The app gets allocated only 1 MPI rank 2) srun --mpi=pmix --pack-group=0 --ntasks=1 : --pack-group=1 --ntasks=4 myapp => srun: fatal: Job steps that span multiple components of a heterogeneous job are not currently supported 3) srun --mpi=pmix --pack-group=0 --ntasks=1 myapp : --pack-group=1 --ntasks=4 myapp => srun: fatal: Job steps that span multiple components of a heterogeneous job are not currently supported So my question is: How do we run an heterogeneous job ? Thanks for your tips, Rafael N.
