Hard code IBM platform so that the irregular collective IO won't call
MPI derived data type.
Description:
IBM MPI-IO has a bug for MPI derived data type.
Solution:
Platforms tested:
copper(AIX,mpcc_r) and heping(Linux, mpich)
Misc. update:
Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
Platforms tested:
Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.
Bug fix
Description:
Removed the cache values of sizeof signed and unsigned int_fast8_t
and int_fast16_t since the vendor changes them often.
Platforms tested:
Tested in Copper only since it affected it only.
Misc. update:
Fix configure bug that appears on SDSC DataStar.
Description:
Two cached "sizeof"s in ./config/powerpc-ibm-aix5.x cause builds
on SDSC Datastar to choke.
Solution:
Commented out the offending "sizeof"s. Included comments indicating
the reason for the change.
Platforms tested:
copper
Misc. update:
n/a
Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.
Bug fix
Description:
Update debugging and profiling flags to include more information.
Platforms tested:
IBM p690 (copper)
too obscure for h5committest
Bug Fix
Description:
The FFLAGS, CXXFLAGS, and CPPFLAGS variables weren't carrying
user-defined values into the Makefiles.
Solution:
Changed the flags from FOO="..." to FOO="$FOO ..."
Platforms tested:
Copper
Verbena
Arabica
Misc. update:
Bug Fix
Description:
In a fit of what can only be described as brain-damagedness, on blue,
frost, etc. (AIX, really), when you include the zlib.h header file
and are specifying that the compiler accept ANSI C, zlib.h undefines
the "const" keyword if you don't have the variable STDC
defined...*boggle*.
Solution:
Included a -DSTDC as a commandline flag for the compiler.
Platforms tested:
Snow (AIX 5.0)
Only affects AIX machines, so no h5committest needed.
Misc. update:
Update
Description:
Revamped the configuration system. The configurations for the Fortran
and C++ libraries are no longer separate from the "main"
configuration system. This involved removing the "configure*" and
"aclocal.m4" files from the fortran/ and c++/ subdirectories. Also
merging settings in the config/ subdirectories into the main config/
subdirectory.
Fortran header files had to be modified a little for Linux. It was
checking if it was a Linux machine by some #defines, however with the
-std=c99 switch, these defines weren't there. I added a check for
some other ones which should be there whether the -std=c99 switch is
used or not.
Platforms tested:
Verbena (Fortran & C++)
Sol (Fortran & C++)
Copper (Fortran & C++)
Modi4 (Parallel, Fortran, & C++)
Misc. update:
Improvement
Description:
RUNPARALLEL is setup with default value when --enable-parallel but only if
CC is not set.
Solution:
set RUNPARALLEL to default value of using poe when --enable-parallel
or when an MPI compiler (e.g. mpcc_r) is used.
Platforms tested:
Copper for both 32 and 64 bit, serial and parallel.
(32bit parallel had a hang problem in configure which is a different but
known problem.)
Note that one still need to setenv AR "ar -X64" for 64bit configure.
Misc. update:
Bug Fix
Description:
The compression stuff includes the "zlib.h" header file. This
file on the SP machine was including another file which would
#define const as nothing if the compiler wasn't a Standard C
compiler.
Solution:
Included a flag to make the compiler into an ANSI compiler.
Platforms tested:
Blue (Only affects powerPC computers)
Misc. update:
Bug fix
Description:
test/dtypes failed badly when -O is used. Trying to recompile test/*
code without -O did not eliminate the errors. So, the failure is
deep in the hdf5 library.
Solution:
For now, removed '-O' from $PROD_CFLAGS so that enable-production will use
no optimization. Need to find out what exactly trigger the errors.
Platforms tested:
Did not do h5committest because this is an AIX configure change only.
Tested it in Copper. Need to test it on other offsite machines.
Misc. update:
Updated release_docs/RELEASE.
Bug fix
Description:
The $RUNPARALLEL is set even when parallel mode is not used.
Then it is used to launch some parallel natured test (e.g. example/ph5example)
which is not compiled to be so. That created some unnecessary problem
in some situation (e.g., Copper cannot "poe a.out" from an AFS space
because of the missing AFS token system bug.
Solution:
Setup RUNPARALLEL only when parallel mode is enabled.
Platforms tested:
Only tested in Copper since the change applies to IBM machines only.
(note that v1.4 will fail by default due to a problem when the default
production mode is used. But that is an error not related to this config file)
Misc. update:
bug fix, features.
Description:
removed the cache of sizeof_long since it varies between 32 and 64 bits.
Set xlc and mpcc_r as the default compiler for serial and parallel modes.
Added -D_LARGE_FILES by default to support large file size.
Added gcc gnu-flags when gcc compiler is used (not working yet.)
Platforms tested:
Tested in Copper only since that is the only AIX machine on site.
Porting to AIX 5.x
Description:
These have been tested out in v1.4. Folding them in here.
aclocal.m4:
Snow's names were not included in the special hack.
Added its names in.
Removed the trailing * in pacific.llnl.gov too.
configure.in:
fortran/configure.in:
Added a case to group all AIX 5.* versions as aix5.x. This allows
them to share one common config/*aix5.x file.
configure:
fortran/configure:
Derived from configure.in (done in eirene).
config/powerpc-ibm-aix4.x:
Added a comment explaining why not to cache sizeof size_t and off_t
fortran/config/powerpc-ibm-aix4.x:
Turned of cache of sizeof size_t and off_t because they are depedent
on compiler options.
config/powerpc-ibm-aix5.x:
fortran/config/powerpc-ibm-aix5.x:
New config file for AIX 5.X
Platforms tests:
LLNL Blue, Frost, Snow, both serial and parallel.
