+build fio. To create an MSI installer package install WiX 3.7 from
+http://wixtoolset.org and run dobuild.cmd from the
os/windows directory.
+How to compile FIO on 64-bit Windows:
+
+ 1. Install Cygwin (http://www.cygwin.com/setup.exe). Install 'make' and all
+ packages starting with 'mingw64-i686' and 'mingw64-x86_64'.
+ 2. Download ftp://sourceware.org/pub/pthreads-win32/prebuilt-dll-2-9-1-release/dll/x64/pthreadGC2.dll
+ and copy to the fio source directory.
+ 3. Open the Cygwin Terminal.
+ 4. Go to the fio directory (source files).
+ 5. Run 'make clean'.
+ 6. Run 'make'.

+ (option=system,percpu) or run unit work
+ calibration only (option=calibrate).
Any parameters following the options will be assumed to be job files,
process Dump info related to processes

- all Enable all debug options
+ all Enable all debug options
random Dump info related to random offset generation
parse Dump info related to option matching and parsing
diskutil Dump info related to disk utilization updates
readv/writev (with queuing emulation) mmap for mmap'ed
io, syslet-rw for syslet driven read/write, splice for
using splice/vmsplice, sg for direct SG_IO io, net

iodepth=x For async io, allow 'x' ios in flight
ratecycle=x ratemin averaged over x msecs
cpumask=x Only allow job to run on CPUs defined by mask.
cpus_allowed=x Like 'cpumask', but allow text setting of CPU affinity.
+ numa_cpu_nodes=x,y-z Allow job to run on specified NUMA nodes' CPU.
+ numa_mem_policy=m:x,y-z Setup numa memory allocation policy.
+ 'm' stands for policy, such as local, interleave,
+ bind, prefer, local. 'x, y-z' are numa node(s) for
+ memory allocation according to policy.
fsync=x If writing with buffered IO, fsync after every
'x' blocks have been written.
end_fsync=x If 'x', run fsync() after end-of-job.
does on the server side, to allow IP/hostname/socket and port strings.
You can connect to multiple clients as well, to do that you could run:
-fio --client=server2 --client=server2 <job file(s)>
+fio --client=server2 <job file(s)> --client=server2 <job file(s)>
