This will place the temporary outputs of the nsys code in your TMPDIR folder that by default is /scratch_local/slurm_job.$SLURM_JOB_ID where you have 1 TB of free space.
This workaround may cause conflicts between multiple jobs running this profiler on a compute node at the same time, so we strongly suggest also to request the compute node exclusively:
#SBATCH --exclusive
Nsight Systems can also collect kernel IP samples and backtraces, however, this is prevented by the perf event paranoid level being set to 2 on Marconi100. It is possible to bypass this restriction by adding the SLURM directive:
#SBATCH --gres=sysfsAlong with the exclusive one.
MPI environment
We offer two options for MPI environment on Marconi100:
