This repository provides Fortran bindings for theSZ3 lossy compression library,allowing seamless integration of SZ3 compression capabilities into Fortran projects. The repository includes a test driver to check the correctness and functionality of the Fortran bindings.

Before using the SZ3 Fortran bindings, make sure you have the SZ3 library installed on your system. You can follow theinstructions from the SZ3 repository.

To build the test driver that makes use of the SZ3 Fortran bindings, follow these steps:

1. Clone this repository:git clone https://github.com/ofmla/sz3_simple_example.git)
2. Navigate to the repository directory:cd sz3_simple_example
3. Modify the Makefile to include the paths to the SZ3 installed library:

• Open the Makefile in a text editor.
• Locate the variablesC_INCLUDE,LIBS, andRPATH.
• SetC_INCLUDE to the directory containing the SZ3 header files (e.g.,-I/path/to/external/SZ3library/include).
• SetLIBS to link against the SZ3 library (e.g.,-L/path/to/external/SZ3library/lib -lSZ3c).
• SetRPATH to specify the runtime library search path (e.g.,-Wl,-rpath=/path/to/external/SZ3library/lib).

4. Build the bindings and the test driver using the modified Makefile:make

After building the project, you can run the provided test driver to ensure that the Fortran bindings work properly.Pleasenote that the test driver requiressample data. Download the sample datafile and place it in the same directory as the test driver executable. Then, execute the following command to run the test driver:

./test_fsz3
