Fortran Bindings for SZ3 Compression Library

Overview

This repository provides Fortran bindings for the SZ3 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.

Prerequisites

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

Testing

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 variables C_INCLUDE, LIBS, and RPATH.
• Set C_INCLUDE to the directory containing the SZ3 header files (e.g., -I/path/to/external/SZ3library/include).
• Set LIBS to link against the SZ3 library (e.g., -L/path/to/external/SZ3library/lib -lSZ3c).
• Set RPATH 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. Please note that the test driver requires sample data. Download the sample data file and place it in the same directory as the test driver executable. Then, execute the following command to run the test driver:

./test_fsz3
