next round will move to using amd-smi |
future options:
# -h Print this help message and exit
# -md Set number of desired devices for multi-device mode, default=1
# -s suppress output, often useful in benchmarking
# -q suppress output, quiet, alias of -s, same as GPURUN_VERBOSE=0
# -m use numactl membind to CPUs in same NUMA domain. Note: Allocation
# fails when not enough memory available on these nodes.
# -l use numactl localalloc to CPUs in same NUMA domain. Note: If
# memory cannot be allocated, alloc falls back to other nodes.
# -nr use numactl ROCR_VISIBLE_DEVICES
# -nm use numactl OMPI_COMM_WORLD_LOCAL_RANK
# --version Print version of gpurun and exit
