  # Iteration Control: Each variable will be looped over to create the jobs to be run.
  # Do not change the variable name. The variable must consist of one or more space
  # delimited strings that are legal values for fio to use in a job file.
  #
  # For now, the only supported variables here are blocksize and randwrite
  #
  # Example: If you have 2 blocksize values, and 3 randwrite values, this will result in 6 jobfiles.
