1.0 Overview and history
------------------------
random Uniform random distribution
zipf Zipf distribution
pareto Pareto distribution
+ gauss Normal (guassian) distribution
When using a zipf or pareto distribution, an input value
is also needed to define the access pattern. For zipf, this
what the given input values will yield in terms of hit rates.
If you wanted to use zipf with a theta of 1.2, you would use
random_distribution=zipf:1.2 as the option. If a non-uniform
- model is used, fio will disable use of the random map.
+ model is used, fio will disable use of the random map. For
+ the gauss distribution, a normal deviation is supplied as
+ a value between 0 and 100.
percentage_random=int For a random workload, set how big a percentage should
be random. This defaults to 100%, in which case the workload
enabled when polling for a minimum of 0 events (eg when
iodepth_batch_complete=0).
+[psyncv2] hipri Set RWF_HIPRI on IO, indicating to the kernel that
+ it's of higher priority than normal.
+
[cpu] cpuload=int Attempt to use the specified percentage of CPU cycles.
[cpu] cpuchunks=int Split the load into cycles of the given time. In
For this case, fio would wait for the server to send us the write state,
then execute 'ipmi-reboot server' when that happened.

-------------------------
To load store write state, read verification job file must contain
the verify_state_load option. If that is set, fio will load the previously
