+Some parameters may take arguments of a specific type.
+Anywhere a numeric value is required, an arithmetic expression may be used,
+provided it is surrounded by parentheses. Supported operators are:
+.RS

.TP
.I str
String: a sequence of alphanumeric characters.
control what sequence of output is being generated. If not set, the random
sequence depends on the \fBrandrepeat\fR setting.
.TP
-.BI use_os_rand \fR=\fPbool
-Fio can either use the random generator supplied by the OS to generate random
-offsets, or it can use its own internal generator (based on Tausworthe).
-Default is to use the internal generator, which is often of better quality and
-faster. Default: false.
-.TP
.BI fallocate \fR=\fPstr
Whether pre-allocation is performed when laying down files. Accepted values
are:
.BI experimental_verify \fR=\fPbool
Enable experimental verification.
.TP
+.BI verify_state_save \fR=\fPbool
+When a job exits during the write phase of a verify workload, save its
+current state. This allows fio to replay up until that point, if the
+verify state is loaded for the verify read phase.
+.TP
+.BI verify_state_load \fR=\fPbool
+If a verify termination trigger was used, fio stores the current write
+state of each thread. This can be used at verification time so that fio
+knows how far it should verify. Without this information, fio will run
+a full verification pass, according to the settings in the job file used.
+.TP
.B stonewall "\fR,\fP wait_for_previous"
Wait for preceding jobs in the job file to exit before starting this one.
\fBstonewall\fR implies \fBnew_group\fR.
used and must be omitted unless it is a valid UDP multicast address.
.TP
.BI (net,netsplice)port \fR=\fPint
-The TCP or UDP port to bind to or connect to.
+The TCP or UDP port to bind to or connect to. If this is used with
+\fBnumjobs\fR to spawn multiple instances of the same job type, then
+this will be the starting port number since fio will use a range of ports.
.TP
.BI (net,netsplice)interface \fR=\fPstr
The IP address of the network interface used to send or receive UDP multicast
send back. For UDP multicast traffic pingpong=1 should only be set for a single
reader when multiple readers are listening to the same address.
.TP
+.BI (net, window_size) \fR=\fPint
+Set the desired socket buffer size for the connection.
+.TP
+.BI (net, mss) \fR=\fPint
+Set the TCP maximum segment size (TCP_MAXSEG).
+.TP
.BI (e4defrag,donorname) \fR=\fPstr
File will be used as a block donor (swap extents between files)
.TP
You can connect to multiple clients as well, to do that you could run:
fio \-\-client=server2 \-\-client=server2 <job file(s)>
+
+If the job file is located on the fio server, then you can tell the server
+to load a local file as well. This is done by using \-\-remote-config:
+
+fio \-\-client=server \-\-remote-config /path/to/file.fio
+
+Then the fio serer will open this local (to the server) job file instead
+of being passed one from the client.
