Code cleanup
Description:
Trim trailing whitespace in Makefile.am and C/C++ source files to make
diffing changes easier.
Platforms tested:
None necessary, whitespace only change
Bug fix.
Description:
Seems like some compilers don't like the "inline" function spec.
Solution:
Removed the inline description for the sub_time function.
Platforms tested:
heping and tg-login.
Misc. update:
Feature, address bug #426
Description:
The h5perf test now also keeps track of the time it takes to:
open a file: Time between start of open and start first read/write
close a file: Time between end of last read/write and end of close.
This information is only displayed if debug output printing is enabled (level 3 or higher)
Solution:
The test actually has all of the data necessary to compute the time it takes to open
and close a file; it just wasn't recording it. Added 4 new timers:
HDF5_FILE_READ_OPEN
HDF5_FILE_READ_CLOSE
HDF5_FILE_WRITE_OPEN
HDF5_FILE_WRITE_CLOSE
that keep track of the time to open/close a file opened for reading/writing.
Platforms tested:
heping and mir
Misc. update:
New Feature.
Description:
Added code and changes so that h5perf (pio) can be built by
standalone mode (that is built by just "h5pcc" without all these
internal files.) With the standalone mode, h5perf can be built
against different versions of hdf5 library and to contrast the
performance among them.
(Note that pio_standalone.c and pio_standalone.h are used in
standalone build only.)
Platforms tested:
Tested in copper and heping.
Bring in sync with v1.4 versions that have copyright statements
added.
Platforms tested:
eirene(pp). Only one machine tested because all changes are merely
comments.
Update
Description:
Updating the source for the PIO performance tests with the current
code that's in the V1.4 branch. It includes the newest command-line
parameters.
Platforms tested:
Linux-pp
Name Change
Description:
Changed the macro's name from "MILLISECOND" to "MICROSECOND" since,
as Quincey pointed out, that's what it is ;).
Platforms tested:
Linux
Bug fix, feature
Description:
Added code to time pure MPI_File_write_xxx and read_xxx routines.
Moved the setting of the timer_g to when timer is created (new)
and destroyed.
Platforms tested:
modi4pp
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).
Platforms tested:
Linux
Purpose:
Feature Fix
Description:
Added timer from open to close for write. Changed reporting of time
for write and read to only measure the actual read/write instead of
the open/close as well...
Platforms tested:
Linux(pp)
Purpose:
Bug Fix
Description:
I wasn't calculating the total time correctly.
Solution:
I had to subtract the previous time from the current time. This
wasn't being done...DOH
Platforms tested:
Linux
Purpose:
Code Cleanup and Feature Add
Description:
Finally checking in the changes I made to the performance code. It
just modularizes it a bit more and performs some more checks, etc. I
also renamed the timer functions to be more inline with how other
things are named here...
Platforms tested:
Linux
Purpose:
bug Fix
Description:
Changed the code so that if parallel stuff isn't enabled, then we
don't compile the parallel code.
Solution:
Cleaned up the code and put #ifdef's around it checking for parallel
flags.
Platforms tested:
Linux
New addition
Description:
Initial version of the Parallel I/O performance measurement program.
Not fully implemented yet but checking them in before I may destroy
them by accident.
Don't run this in small file system (like AFS or eirene) since it
generates gigabytes test files.
Platforms tested:
modi4 64bits. It compiled and ran but took a long time because
the current test parametes are too "wild".
