  # Usage:
  -# srun -n1 --exclusive sweep.sh -x raja-perf.exe [-- raja perf args]
  +# srun -n1 --exclusive sweep.sh -x raja-perf.exe [-- <raja perf args>]

  # Examples:
  -# lalloc 1 lrun -n1 sweep.sh -x raja-perf.exe -- args

  # # run a sweep of default problem sizes with executable `raja-perf.exe`
  # # with args `args`
  #
  # srun -n1 --exclusive sweep.sh -x raja-perf.exe --size-min 1000
  -# --size-max 10000 --size-ratio 2 -- args
  +# --size-max 10000 --size-ratio 2 -- <args>
  # # run a sweep of problem sizes 1K to 10K with ratio 2 (1K, 2K, 4K, 8K)
