the job to exit. The same format as rate is used for read vs
write seperation.

+ latency. It will exit with an ETIME error.

ratecycle=int Average bandwidth for 'rate' and 'ratemin' over this number
of milliseconds.
allows a range of CPUs. Say you wanted a binding to CPUs
1, 5, and 8-15, you would set cpus_allowed=1,5,8-15.
+numa_cpu_nodes=str Set this job running on spcified NUMA nodes' CPUs. The
+ arguments allow comma delimited list of cpu numbers,
+ A-B ranges, or 'all'. Note, to enable numa options support,
+ export the following environment variables,
+ export EXTFLAGS+=" -DFIO_HAVE_LIBNUMA "
+ export EXTLIBS+=" -lnuma "
+
+numa_mem_policy=str Set this job's memory policy and corresponding NUMA
+ nodes. Format of the argements:
+ <mode>[:<nodelist>]
+ `mode' is one of the following memory policy:
+ default, prefer, bind, interleave, local
+ For `default' and `local' memory policy, no node is
+ needed to be specified.
+ For `prefer', only one node is allowed.
+ For `bind' and `interleave', it allow comma delimited
+ list of numbers, A-B ranges, or 'all'.

startdelay=time Start this job the specified number of seconds after fio
has started. Only useful if the job file contains several
jobs, and you want to delay starting some jobs to a certain
points in the job file. A stone wall also implies starting
a new reporting group.
-new_group Start a new reporting group. If this option isn't given,
- jobs in a file will be part of the same reporting group
- unless separated by a stone wall (or if it's a group
- by itself, with the numjobs option).
+new_group Start a new reporting group. See: group_reporting.
numjobs=int Create the specified number of clones of this job. May be
used to setup a larger number of threads/processes doing
- the same thing. We regard that grouping of jobs as a
- specific group.
-
-group_reporting If 'numjobs' is set, it may be interesting to display
- statistics for the group as a whole instead of for each
- individual job. This is especially true of 'numjobs' is
- large, looking at individual thread/process output quickly
- becomes unwieldy. If 'group_reporting' is specified, fio
- will show the final report per-group instead of per-job.

thread fio defaults to forking jobs, however if this option is
given, fio will use pthread_create(3) to create threads
[net] proto=str The network protocol to use. Accepted values are:
tcp Transmission control protocol
- udp Unreliable datagram protocol
+ udp User datagram protocol
unix UNIX domain socket
When the protocol is TCP or UDP, the port must also be given,
