Hi everyone! I have SLURM cluster with several nodes with 16 vcpus per node. I've tried to run the following code:
#SBATCH --nodes 2 #SBATCH --ntasks 2 #SBATCH -c 16 srun --exclusive --nodes=1 program1 & srun --exclusive --nodes=1 program2 & wait program1 and program2 needs 16cpus each and I expected that 2 nodes with 32 cores would be allocated and program1 would be ran on the first node and program2 on the second one, but I got the following error message: srun: error: Unable to create step for job 364966: Requested node configuration is not available If I use only --nodes and --ntasks keys, sbatch allocates 2 nodes with 2 cpus and if I use --nodes and -c options, I get message that --ntasks should be defined. If I set --ntasks=1, SLURM set nnodes to 1. How can I run this two programs in one batch, each on one node and 16 vcpus? ------ Kind regards, Daniil Vakhrameev
