hdf installation
------------------------
./configure --enable-parallel --with-szlib=/apps/rhel5/graphics/x86_64/intel/11.1.038/szip/lib --prefix=/usr/rmt_share/scratch95/w/unknownuser/pnetcdf/ --disable-f90
compiling hdf
------------------
If szip was used when building HDF5, you must also use -lsz.-lm for math library
mpicc -o htest htest.c -I/usr/rmt_share/scratch95/w/unknownuser/pnetcdf/include \
-L/usr/rmt_share/scratch95/w/unknownuser/pnetcdf/lib
-I/apps/rhel5/graphics/x86_64/intel/11.1.038/szip/include
-L-I/apps/rhel5/graphics/x86_64/intel/11.1.038/szip/include -lhdf5 -lz -lm
when building with parallel you need to set the CPPFLAGS=-DgFortran.
