Fortran 90 General I/O Interface (F90GIO) provides I/O interface for NetCDF, HDF4, HDF5 reading/writing with Fortran 90 languages. It is developed in the hope of allieviating researchers' burden in atmospheric and oceanic science to deal with either re-analysis, forecast, or remote sensed data. Instead of wasting time learning these techniques, researchers may prefer to focus on the scientific problems. With this thought in mind, I decide to deliever this package to the public. Most of the routines have been tested both on Mac Pro and Linux clusters.
This README file contains information about: I. what compiler flags should be included when compiling NetCDF, HDF4, HDF5 libraries; II. how to compile F90IO library, III. how to use F90IO library.
If you find this package helpful, and you are using it in your papers, please acknowledge it in your acknowledgement section in your papers if possible. Thanks!
- Add fast I/O libs for NetCDF and H5 files:
ncio
andh5io
libs remove lots of checks in F90GIO, and reduce the times of open/close files.
-
For installing HDF4, if you'd like to use my netcdf & hdf4 module simultenously, you need to disable the netcdf-I/O capability:
--disable-netcdf
when runnning configure. Other important flags for F90GIO includes:
--enable-fortran F77=YOUR_COMPILER (e.g., F77=ifort)
The general flags when you configure HDF4 library can be found in the file named INSTALL in the directory
~/release_notes
of the official source code pakage or see this file online (https://www.hdfgroup.org/ftp/HDF/HDF_Current/src/unpacked/release_notes/INSTALL). -
For HDF5 compilation, you need to add flag:
--enable-fortran --enable-fotran2003
other general flags when configuring the HDF5 can be found in the directory of
~/release_docs
of the official source code package or see this file online (http:https://www.hdfgroup.org/ftp/HDF5/current/src/unpacked/release_docs/INSTALL)
"make all" in the current directory, and a directory "build" will be created here. The libs and includes will be under "build/libs" and "build/include".
config/env.sh sets the required environmental vars used by CMAKE.
-
To turn off specific lib, you can modify Makefile at the current directory as:
-
turn off hdf4
mkdir build . config/env.sh; cd build; cmake -DBUILD_H4=off ..; make; make test
-
turn off netcdf
mkdir build . config/env.sh; cd build; cmake -DBUILD_NC=off ..; make; make test
-
turn off hdf5 by
mkdir build . config/env.sh; cd build; cmake -DBUILD_H5=off ..; make; make test
-
-
for hdf5 libs, if you are using hdf5 libs with major version <= 1.8 add the
H5_VERSION_1_8=ON
when running cmakemkdir build . config/env.sh; cd build; cmake -DBUILD_H5=on -DH5_VERSION_1_8=ON ..; make; make test
-
install Fast I/O libs (currently support NC and HDF5)
mkdir build . config/env.sh; cd build cmake .. -DBUILD_NC=ON -DBUILD_H5=on -DH5_VERSION_1_8=ON -DBUILD_FAST_IO=ON make; make test
