I've also seen this issue when running with multiple hosts. The error looks to come from

benchmark.sh. line 280

mpirun -hosts $hosts -np $num_accelerators python3 dlio_benchmark/dlio_benchmark/main.py --config-path=$CONFIG_PATH workload=$config_name ++workload.workflow.generate_data=False ++workload.workflow.train=True ${prefixed_array[@ ]} ${EXTRA_PARAMS[@]}

man mpirun
...
Specifying Host Nodes
Host nodes can be identified on the mpirun command line with the -host option

Note -host vs -hosts

The mpirun/mpiexec command differs from system to system. It is good to modify ./benchmark.sh accordingly. Maybe Johnu can add this note in the documentation. Huihuo
