Hi


I am trying to run a simulation using CONVERGE CFD and if I give the total process count more than 240 the job is getting killed and abort trace files are generated
Stack trace(s) written to abort_trace_rank[#].out
I am running on an HPC with 32 nodes and each node has 24 cpu processors my slrum script is something like this




#!/bin/bash
# Slurm job submission script for Kinetics and SRM Engine Suite.
# It is being used by a wrapper script.
# DO NOT EXECUTE THIS DIRECTLY ON THE COMMAND LINE!
# DO NOT SUBMIT THIS DIRECTLY TO SLURM!

#!SBATCH --nodes=3 # -N number of nodes
#SBATCH --ntasks=240 # total, <=number of nodes*20
#SBATCH --output ShipFlow.%u.%j.%N.stdout.txt # (%u,%j,%N)=(user, job allocation #, node)
#SBATCH --error ShipFlow.%u.%j.%N.errout.txt #
#SBATCH --mail-type=END,FAIL # notifications for job done & fail
#SBATCH --hint=nomultithread
#! Number of nodes and tasks per node allocated by SLURM (do not change):
#!numnodes=$SLURM_JOB_NUM_NODES
#!mpi_tasks_per_node=$(echo "$SLURM_TASKS_PER_NODE" | sed -e 's/^\([0-9][0-9]*\).*$/\1/')

#! Number of MPI tasks to be started by the application per node and in total (do not change):
#!np=$[${numnodes}*${mpi_tasks_per_node}]

CMD="mpirun -n 240 converge-hpcx -l super"
echo -e "\nExecuting command:\n$CMD\n==================\n"
eval $CMD






any idea why I am unable to use more resources
