Purpose:
Bug Fix
Description:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
immediately). This ensures that after the error occurs, there is enough address
space left to flush the entire file to disk, so no data is lost.
A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html
Platforms tested:
sleipnir, copper (parallel), verbena, arabica, Windows (Visual Studio 7)
Misc. update:
Fix
Description:
Fixed the install-doc command...
Solution:
Mostly just fixed in the config/conclude.in file, but updated the doc
directories with Makefile.ins and Dependencies so that they'd work.
Platforms tested:
Linux, Solaris
New doc and update
Description:
The original openmp-hdf5.html contains a bunch of C source code.
HTML does not like source code, especially C-code that contained
<...>. It gobbled it badly.
Solution:
Moved the source code to a new file, openmp-hdf5.c and make a
reference to it from openmp-hdf5.html.
Platforms tested:
Viewed via IE on an NT box.
"New" document
Description:
Raymond has prepared and added a new document reporting his
experience of using HDF5 with OpenMP. It was checked in as
a .txt file but browsers could not display it properly, at least
not for the MS-IE.
Solution:
I renamed the file from openmp-test.txt to openmp-hdf5.html,
added in simple mind html control statement (<pre>), added
an entry to the TechNote.html so that it can be found with
other technical notes.
Platforms tested:
Viewed by MS-IE.
Documentation of TS Library
Description:
This is the document Chee Wai wrote up about the thread safe
version of the HDF5 library. I just put it in HTML format and
checked it in...
Platforms tested:
Netscrape
Purpose:
This file describes the experiencing of OpenMP with hdf5.
Description:
All detailed description is in the file.
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
Everything was done on modi4.
Feature symmetry
Description:
A while ago I needed to get the 'type' of data being accessed during writes
to the VFL driver, so I put in code to get the information down there.
Albert asked for the same information during reads, so I've added that in.
Tested:
Netscape
Adding new document
Description:
Adding VFL.html (Virtual File Layer) to HDF5 Technical Notes.
August 1999 version. Will be updated for R1.4 by developer.
Platforms tested:
IE 5
Update
Description:
Added the description of the environment variable HDF5_MPI_OPT_TYPES
which controls the use of optimized MPIO routines.
Platforms tested:
Viewed via IE.
Feature
Description:
Added a new document of all the controls (compiler macros,
environment variables, ...) that affect the functionality of
the libraries and tools.
Platforms tested:
Viewed with MS IE.
