Improvements for parallel library. If you have a properly
working mpicc you should be able to just say:
$ CC=mpicc ./configure
and you will see
checking for mpirun... /usr/local/mpi/bin/mpirun
checking for parallel support files... skipped
checking how to run on one processor...
/usr/local/mpi/bin/mpirun -np 1
checking how to run in parallel...
/usr/local/mpi/bin/mpirun -np $$NPROCS
To quote from the INSTALL file....
*** Parallel vs. serial library
The HDF5 library can be configured to use MPI and MPI-IO for
parallelizm on a distributed multi-processor system. The easy
way to do this is to have a properly installed parallel
compiler (e.g., MPICH's mpicc or IBM's mpcc) and supply that
executable as the value of the CC environment variable:
[NOTE: mpcc is not tested yet]
$ CC=mpcc ./configure
$ CC=/usr/local/mpi/bin/mpicc ./configure
If no such wrapper script is available then you must specify
your normal C compiler along with the distribution of
MPI/MPI-IO which is to be used (values other than `mpich' will
be added at a later date):
$ ./configure --enable-parallel=mpich
If the MPI/MPI-IO include files and/or libraries cannot be
found by the compiler then their directories must be given as
arguments to CPPFLAGS and/or LDFLAGS:
$ CPPFLAGS=-I/usr/local/mpi/include \
LDFLAGS=-L/usr/local/mpi/lib/LINUX/ch_p4 \
./configure --enable-parallel=mpich
If a parallel library is being built then configure attempts
to determine how to run a parallel application on one
processor and on many processors. If the compiler is mpicc
and the user hasn't specified values for RUNSERIAL and
RUNPARALLEL then configure chooses `mpirun' from the same
directory as `mpicc':
RUNSERIAL: /usr/local/mpi/bin/mpirun -np 1
RUNPARALLEL: /usr/local/mpi/bin/mpirun -np $${NPROCS:=2}
The `$${NPROCS:=2}' will be substituted with the value of the
NPROCS environment variable at the time `make check' is run
(or the value 2).
./testpar/Makefile.in
Saying `make check' (or `make test') will run the tests on two
processors by default. If you define NPROCS then that many
processors are used instead:
$ NPROCS=4 make check
./configure.in
Fixed (hopefully) bugs with detecting whether __attribute__
and __FUNCTION__ are special keywords for the compiler.
./Makefile.in
Saying `make install' from the top level directory shows
instructions for using shared libraries.
./config/commence.in
./src/Makefile.in
./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
Moved the @top_srcdir@ into the makefiles because it was
expanded too early and had the wrong value.
./INSTALL
Added a warning that if the wrong version of hdf4 tools are
installed then `make check' will fail in the tools directory.
