independent fio invocations. Unfortuantely this also breaks
the strict time ordering between multiple device accesses.
+replay_align=int Force alignment of IO offsets and lengths in a trace
+ to this power of 2 value.

+replay_scale=int Scale sector offsets down by this factor when

write_bw_log=str If given, write a bandwidth log of the jobs in this job
file. Can be used to store data of the bandwidth of the
jobs in their lifetime. The included fio_generate_plots
bytes. The action can be one of these:
wait Wait for 'offset' microseconds. Everything below 100 is discarded.
+ The time is relative to the previous wait statement.
read Read 'length' bytes beginning from 'offset'
write Write 'length' bytes beginning from 'offset'
sync fsync() the file
