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.)
Platforms tested:
modi4(pp) and eirene(pp).
Purpose:
Bug Fix
Description:
Fixed so that it will display the correct timing data. It will also
write to the correct file (which it wasn't before).
Solution:
Put the code in for displaying the time. Had to change the way I was
passing an object to the pio_fopen() function from just being a
structure to being a pointer so that the changes could be propagated
back.
Platforms tested:
Linux
Purpose:
Small Fixes
Description:
After conversation with Albert, here are some small fixes for the
performance stuff. Not too significant. Though, we did add the
"buffer size" as a parameter I pass to the engine.
Purpose:
Feature Fix
Description:
Added code so that it measures the time it takes to do I/O and return
that to the calling function.
This code doesn't quite work yet. There is something wrong with the
MPI code in the "pio_engine.c" file...I don't know what's up with
it...
Platforms tested:
Linux
Bug fix
Description:
Cleaned up obvious syntax errors to make it to compile.
Changed unnecessarily unsigned variables to signed to avoid
messy compiler warnings.
Platforms tested:
eirene (parallel)
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".
