Add netcdf

[smaeyama]

NetCDF4+Parallel HDF5 is added for GKV binary output. This is the parallel file I/O of NetCDF4 interface with Parallel HDF5 engine(, and is NOT parallel-NetCDF (pnetcdf).)

src/gkvp_fileio_fortran.f90 is a module for Fortran binary output used so far, src/gkvp_fileio_netcdf.f90 is a new module for NetCDF4+Parallel HDF5.

In Makefile, these modules are switch by choosing appropriate source file during compilation, FILEIO=gkvp_fileio_fortran or FILEIO=gkvp_fileio_netcdf

For now, verification tests of NetCDF4+parallel HDF5 are finished on

• Ubuntu (WSL2) on laptop (FFTW and NetCDF by SPACK)
• p-srv at P Lab. (build by ifort, hdf5-1.10.7, netcdf-c-4.7.4, netcdf-fortran-4.5.3)
• JFRS-1 at QST (Cray, XC50. module load cray-fftw cray-hdf5-parallel/1.10.5.1 cray-netcdf-hdf5parallel/4.6.3.1)
• Plasma Simulator at NIFS (NEC, SX-Aurora TSUBASA. module load NECNLC-sx netcdf-parallelIO-fortran-sx/4.5.2)

There are still problem of NetCDF4+parallel HDF5 on some systems (I am now asking to helpdesk):

• ITO at Kyushu Univ. (Fujitsu PRIMERGY CX2550/CX2560 M4. This seems to be just a problem of a older version of NetCDF)
• FLOW at Nagoya Univ. (FUJITSU PRIMEHPC FX1000. Parallel HDF5 does not work?)
• Fugaku at RIKEN (FUJITSU PRIMEHPC FX1000. Parallel HDF5 does not work?)

NetCDF on ITO supercomputer is now updated to NetCDF-C 4.7.4 and correctly works.
