New feature
Description:
All datasets were 1D only before. Added -g to use 2D datasets such

Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:
Ran this script in each directory:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end

Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

feature change, new feature.
Description:
Had the HDF5_PARAPREFIX default set to /tmp.
Changed it to null so that data files are created in current directory
by default.
Also added a code to print data filename used when debug level > 0.

Code cleanup
Description:
Remove the fill-value option entirely, since the 1.5.x library's default
behavior is now the same as the 1.4.x behavior and also there is no
corresponding code for implementing fill-values with the POSIX or MPI-I/O tests.

Compatibility fix
Description:
The H5P[set|get]_fapl_mpiposix calls changed between v1.4.x and v1.5.x.
Solution:
Wrap them in the v1.4 backward compatibility #ifdefs and update tests, etc.

Bug Fix

another parameter, I didn't change it in these files.

Update, Bug Fix, and Feature Add
Description:
- Updated how AC_{ENABLE,WITH} help messages were being generated.
Autoconf now gives you an AC_HELP_STRING macro to use to create
them.
- Fixed the problem with Linux LFS on RedHat 7.3 machines. It wasn't
finding getdents64(), so we can't rely on that being present
anymore...
- Added GPFS detection and setting.
- Updated how compression is specified. It's no longer necessary to
test for HAVE_ZLIB_H, HAVE_LIBZ, and HAVE_COMPRESS2. The one macro
{H5_}HAVE_COMPRESSION takes care of all of these.
Solution:
Changed the check for Linux LFS from looking for getdents() to
looking at the version number of the kernel (using the uname -r
command). You can still override with the --enable-linux-lfs switch
if you really believe that your <2.4 kernel has LFS support.

Feature Addition
Description:
Added feature which prints out the parameters and the MPI_Info object
for a run for each process.
Added some functions for the GPFS system. They are ifdef'ed out right
now (well, they need to ahve the non-existant H5_HAVE_GPFS macro set)
and aren't in use just yet. But the stub functions are there.

Bug fix
Description:
Was not able to handle data size (file size) larger than 32bits.
Was using long, which is only 4 bytes big in SP, thus overflowing
into negative when trying to address 2GB or larger.
Solution:
Changed those variables involved in file size/offset calculation
to type off_t. (If a certain system/compiler has off_t defined
as 4 bytes, it can't write to file size larger than 2GB anyway.)
Note that the lseek of SP with -D_LARGE_FILE still fails for
offset larger than 2GB (works for 2GB). That has to be fixed
soon.
Platforms tested:
burrwhite (linux 2.4) and modi4 parallel.

Modification
Description:
Put some of the variables into the global space so that random
functions can access them. (The output and timer variables which
point to the output file and timer resp.)
Placed the debug level 4 prints into the timer module so that it's
easier to automatically put timer start/stop printfs for new timers
which are created.
Added timers for MPI Time calls (called HDF5_MPI_WRITE and
HDF5_MPI_READ).

Code cleanup
Description:
Platform dependent code related to the struct stat and fstat
calls polluted source codes. Hard to maintain.
Solution:
Platform dependent code are moved to H5private.h and then internal
code can #include H5private.h. Repeat those macro definition for
the stdio and multi drivers since they area examples for writing
a virtual file driver. They must not use any internal code.
Platforms tested:
eirene (parallel), modi4 (serial including gass driver.)

Bug Fix
Description:
So, for Raw I/O in parallel, if you open a file with truncation by
multiple processes, it looks as if one process could open the file
and start writing to it while another process also opens the file
with truncation, thus wiping out all of the stuff the first process
wrote to the file.
This is bad.
Also added some garbage collection to the pio_perf routine to reclaim
the space taken by some of the tables.
Solution:
Placed an MPI_Barrier() statement after the Raw open()/create() call
so that all processes are synced up before they start writing to the
file.
Added free() calls to the tables which weren't being free'd.

Purpose:
Feature Fix
Description:
Changed so the "pio_perf" module handles creating and destroying the
MPI Comm. Worked it so we get the minimum, maximum, and average times
over a set of iterations.
Solution:
Lots. Had to pull the MPI Comm code from the "pio_engine" module and
place it in the "pio_perf" module. Then worked on a way to have all
processes send their time output to process 0, who collects it and
gives back the min, max, and avg times for the iterations.
Platforms tested:
Linux. Doesn't work if you use more than 1 processor...*hrmph*

Purpose:
Feature Changes
Description:
Okay, I needed to add in more parameters so that the user can modify
how things are supposed to work with the PIO programs. Also needed
to change the algorithm a bit to make these work. And needed to add
in timing for the READ option.
Solution:
Added the above things. The parameters took a major rewrite of the
command-line parsing stuff. Here's the usage statement:
usage: pio_perf [OPTIONS]
OPTIONS
-h, --help Print a usage message and exit
-d N, --num-dsets=N Number of datasets per file [default:1]
-f S, --file-size=S Size of a single file [default: 64M]
-F N, --num-files=N Number of files [default: 1]
-H, --hdf5 Run HDF5 performance test
-i, --num-iterations Number of iterations to perform [default: 1]
-m, --mpiio Run MPI/IO performance test
-o F, --output=F Output raw data into file F [default: none]
-P N, --max-num-processes=N Maximum number of processes to use [default: 1]
-p N, --min-num-processes=N Minimum number of processes to use [default: 1]
-r, --raw Run raw (UNIX) performance test
-X S, --max-xfer-size=S Maximum transfer buffer size [default: 1M]
-x S, --min-xfer-size=S Minimum transfer buffer size [default: 1K]
F - is a filename.
N - is an integer >=0.
S - is a size specifier, an integer >=0 followed by a size indicator:
K - Kilobyte
M - Megabyte
G - Gigabyte
Example: 37M = 37 Megabytes
Platforms tested:
Linux, but not fully finished...

Bug fix (or more like feature)
Description:
MPI_File_open does not truncate the filesize if file already exists.
This created confusion during debugging as what the real file size
is. It also interfere the real write bandwidth since the times
required to allocate new disk-space vanishes for subsequent writes
that are for offset shorter than previous file sizes.
Added a MPI_File_set_size to reset the file size to 0 for every new
file.
Another bug is that the 'remove()' call may not work for MPIO/PHDF5
files. (e.g., filename may have some MPI prefix like "pfs:filename").
Replaced "remove" with MPI_File_delete for those cases.

Bug fixes, new features
Description:
There was a coding error in handling file open flags. Changed it
to use &.
Added do_cleanup to cleanup temporary test files but only if
$HDF5_NOCLEANUP is not set. This is consistent with other test programs.
Added logic so that each process is writing its own slabs of data only.
Moved the number of process, rank of process and the communicator used
for PIO run to be global variables. Makes the coding easier. (but this
is not thread-safe.)

Description:
Fixed so that it will display the correct timing data. It will also

structure to being a pointer so that the changes could be propagated
back.
