ansify, prototypes, scope limitations.
V2.1 (kcollins):
Simplified auto mode logic. auto test now runs from
MEGABYTES_START to MEGABYTES_END and from RECLEN_START
to RECLEN_END with values multiplied by MULTIPLIER
each iteration. Range set to (4K...16M) for RECLEN
and (1M...512M) for MEGABYTES. (the physical I/O
tests for RECLEN <4K take several hours on a 1200).
Enlarged MAXBUFFERSIZE to 16MB for large record tests.
Added error checking for mallocs (!-).
Changed multibuffer code to use all of MAXBUFFERSIZE
as a circular buffer, with the number of buffers
varying as MAXBUFFERSIZE/reclen. This corrects
problems where MAXBUFFERSIZE*MAXBUFFERS was very large.
Also modified auto mode so that tests where
reclen>filesize are skipped.
Modified preadv code to vary the number of buffers as
necessary such that they will fit in min(MAXBUFFERSIZE,filesize).
This fixes problems where the number of buffers in
the i/o vector exceeded the size of mainbuffer.
Added bzero for buffer when it is first malloc'd. This
ensures that it is initialized before use.
Created a script (profile.fs) that runs a series of tests
to generate a "box" around common application variables
such as filesize, buffer size, buffer encachement, and
number of concurrent processes. This is intended to serve
as the "standard" filesystem profile.
buffer reset to mainbuffer before each test loop
V2.3 (kcollins):
added -F option to write to specify pathnames for throughput
tests (allowing throughput tests to multiple filesystems).
V2.4 (capps):
Changed preadv/pwritev to use a non-sequential access pattern.
Changed the version number.
Moved all user interface values to KB. This simplifies
the user interface. (consistant scaling) and it also
allows one to start with 512kb file. This is very important
since the first indirect block causes a significant
slowdown in the initial write cases.
V2.5 (capps):
Re-structure and cleanup.
V2.6 (kcollins)
Bug fix for the throughput tests.
V2.7 (capps):
Added -o flag. This makes all file opens for writes
have the O_SYNC flag set. This makes all writes go
to disk before competion. This is useful for seeing
what the media can do without the buffer cache helping.
V2.8 (capps):
Added -V flag. This turns on pattern verification. If
the user were to type:
-V 165
Then bit pattern 0xa5 would be placed in every byte in the
buffer and when read back from buffer cache, or disk,
it will be verified to be correct. If it fails then
the error handler will specify the byte location of the
miscompare.
V2.9 (capps):
Added fread/re-fread, fwrite/re-fwrite to list of tests.
Added -E to allow the user to run pread and friends as an option.
V2.10 (capps):
Added -R. This will generate Excel compatible files that
can then be imported into Excel and graphed.
Added support for 5 targets to the makefile.
Added -M This prints out the uname -a stuff about a machine.
Added -O This gives all results in operations/sec instead of KB/sec.
More code cleanup. Update comments.
V2.11 (kcollins)
added -A. Auto mode with no crossover and read/write tests only
changed default record size to 64KB (from 512 bytes)
V2.12 (capps)
Added shared memory barrier sync for throughput mode. This
provides much finer control over the actual timeing
of the children.
Added mmap() for BSD (Convex) machines that do not
have System V shared memory.
Added two ways of showing throughput results. The second
method takes into consideration children that lag behind
due to slow devices, and gives results that are more accurate.
Cleanup of some tab problems in throughput results.
Cleanup of floating point output taking to much space.
Added -d to allow a variable delay comming out of the barrier
in the throughput tests.
V2.12 (kcollins)
added declaration for create_list to make ansi c compiles work
several fixes to some of the SPPUX 5.x make targets
added date run to banner (hope this doesn't break your scripts $-)
V2.13 (capps)
Added "stone walling". During throughput tests, if one process
finishes then all others are sent a signal to tell them
to stop. (The parallel region has finished). This provides
better numbers for throughput.
Only bzero or fill min(reclen,CACHE_SIZE) this saves a bunch
of paging on workstations with small memory systems.
Fixed broken target in the makefile.
Note: use of -d is not advised. It makes the children not run
in parallel.
V2.14 (capps)
Bug fix to avoid anomaly in SPP-UX. In SPP-UX the filesystem
code preallocates meta-data to improve initial file writes.
The first indirect block allocation was causing a block
of zeros to be written syncronously. In SPP-UX the filesytem
code preallocates zero filled blocks when the first writer
touches a filesystem after a sync. A pool of on disk zero'd
blocks are created asynchronously and handed out to writers
when they cross the boundry into the first level indirect
and would have had to stop and wait for the zero filled
block to be written. Iozone's testing methodology was not
allowing the OS to have any time to complete the async
pre-allocation and was not showing the speed up that real
applications would see.
V2.15 (capps)
Improve throughput testing mode.
V2.16 (capps)
Added -U option. This allows the filesystem to be unmounted
and remounted between tests. This guarentees that the buffer
cache is cold.
V2.17 (capps)
Added -T option. This makes the throughput tests use
threads instead of processes. Currently using pthread_create(),
pthread_self(), and pthread_exit().
Cleaned up file cleanup mechanism. Control C will now cause
all temp files to be deleted. Removed all signals used to
control sub-processes.
V2.18 (capps)
Cleanup. Added read stride, read backwards to the throughput
tests. Various bug fixes
V2.19 (capps)
Removed all calls to malloc() and all use of system V shared
memory. mmap() is much easier to deal with. As for malloc()
HP programs are very limited on the ammount of malloc() space
and not nearly so constrained on mmap() memory. It was necessary
to move to mmap() since multiple threads all need buffers in
the processes address space.
Removed dependency on first thread being number 2. Iozone now
probes to find out what the thread library will return for
the first thread. This makes the switching thread libraries
much easier.
V2.20 (capps)
Children now set stop_flag and shutdown all other children.There
is no further need to tell the parent to distribute the stop_flag.
verify, purge, and osync are now supported in the throughput
tests. Fixed bug where pthreads stack size was causing
segmentation violation when purgeit() was called for buffer
that were greater than 256kb.
V2.21 (capps)
Enhanced throughput reporting. Now provides:
Child throughput, Parent throughput, Minimum throughput for
any child in the group, Maximum throughput for any child in the
group, and Minimum transfer count. Due to stone walling
not all children write the full requested size. This
minimum transfer count provides the user with knowledge of
how much work was performed by the slowest child.
Added -C flag. This allows the user to see all of the transfer
counts for each child. Had to add system 5 shared memory back.
Linux does not support mmap(MAP_ANONYMOUS|MAP_SHARED). So it
must use SYSV shared memory get get sharing working.
V2.22 (capps)
Made changes to make iozone work correctly on Linux on a
PC. Changes are just scaling down the test to fit on a
pc, and scaling down shared segments to < 16 Meg so it
can run on an Intel 386 class machine.
Added: -L # Set the processor cache line size in bytes.
Added: -S # Set the processor cache size in kbytes.
Removed spin wait in parent waiting for threads to
finish each throughput test. Code not uses thread_join().
Fixed -O (operations/sec) mode to work in throughput tests.
V2.23 (capps)
Close small timing hole where thread/process has set stop flag
and others are in a system call. The hole allowed threads/processes
to continue to increment work done after one had finished and
told the others to stop. The result was that the children would
report slightly high numbers as they were not truely parallel
at the finish line. Added random read throughput test.
Fixes for VxFS small extents being created by prime_zb() functions.
Provides more details about the throughput run.
V2.24 (capps)
Added support for -R (Excell chart generation) to the throughput
tests. Also added support for the -O (ops/sec) to the throughput
Excell chart.
V2.25 (capps)
Added support for selecting which test to run. -i #
-i 0 -i 3
will run write and read-backwards tests only. For a list
of the test numbers type iozone -h.
V2.26 (capps)
Added support for LARGE_FILES for the hpux-11.0 target.
V2.27 (capps)
All tests now verify one long word of data from each page
written/read to/from the file. This is to level the
playing field with systems that do not move data
when "read" or "write" is called, but instead just
map the file and perform the I/O when the address space
is touched. Benchmarks that do not validate the data
,at least touch each page, do not measure the read/write
times just the map times.
Note: The -V option still verifies each byte of the buffer,
the default is now to verify one long from each page.
V2.28 (capps)
Added support for benchmarking mmap() files.
Added more command line options. -B -G -D
B = Use mmap() files for the benchmark.
G = Use msync(MS_SYNC) for mmap files.
D = Use msync(MS_ASYNC) for mmap files.
V2.29 (capps)
Bug fixes for:
Combination of running individual tests and mmap() files support.
Stride read bug that caused only portions of the total file to be
examined.
V2.30 (capps)
Fixups for build under SPP-UX
V2.31 (capps)
Fixups for build under Linux.
Added -j ### to support user setting the stride size for the
stride read benchmark.
V2.32 (capps)
Add support for IRIX and IRIX64.
V2.33 (capps)
Add support for POSIX async I/O benchmarking. Uses a library
to interface to POSIX async I/O model. The library provides
and extended async_read() interface. It takes the standard
calling options of read() but also allows the application to
perform read-ahead with a stride. (positive or negative)
and allows the user to specify how much read ahead to
perform.
Tested on HP-UX 11.0, Linux, SGI Origin.
V2.34 (capps)
Added -k. This allows POSIX async I/O to utilize the buffer
specified and not to perform any bcopys. Fixes to make
multi-threadedness work on SGI Origin.
V2.34 (capps)
Added [-k #]. This allows POSIX async I/O to utilize the buffer
specified and not to perform any bcopys. Fixes to make
multi-threadedness work on SGI Origin.
V2.36 (capps)
Iozone is now a 64 bit application. It may be compiled for either
64 bit or 32 bit machines. The makefile supports 64 and 32 bit
targets for machines that support 32 & 64 bit targets.
All version numbers are now automatically generated by
RCS. This is the last time we have to bump the version
number by hand.
-----------------------------------------------------------------------------------
Changed over to RCS source control here:
Version Numbers are reset at this point back to Version 1.1.

Add time resolution output, and fix the divide by zero when the time in
a system call turns out to be Zero. This will introduce distortion for machines
that have very fast system calls and very poor time resolution. Windows

all calls that take less than 50 Milli seconds will be rounded up to
cost 50 milliseconds.
