Levenberg Marquardt curve fitting (lm-fit) in
- CPU
- CUDA
forked from github.com/gpufit/Gpufit described in Sci Rep 7, 15722 (2017).
Binary distribution
The latest Gpufit binary release, supporting Windows 32-bit and 64-bit machines, can be found on the release page.
Documentation
Documentation for the lm-fit library is build autmatically using GitHub Pages https://optiqs-lab.github.io/lm-fit/ using the markdown files provided in docs directory.
Building Gpufit from source code
Instructions for building Gpufit are found in the documentation: Building from source code.
Using the Gpufit binary distribution
Instructions for using the binary distribution may be found in the documentation. The binary package contains:
- The Gpufit SDK, which consists of the 32-bit and 64-bit DLL files, and the Gpufit header file which contains the function definitions. The Gpufit SDK is intended to be used when calling Gpufit from an external application written in e.g. C code.
- Gpufit Performance test: A simple console application comparing the execution speed of curve fitting on the GPU and CPU. This program also serves as a test to ensure the correct functioning of Gpufit.
- Matlab 32 bit and 64 bit bindings, with Matlab examples.
- Python version 2.x and version 3.x bindings (compiled as wheel files) and Python examples.
- Java binding, with Java examples.
Examples
There are various examples that demonstrate the capabilities and usage of Gpufit. They can be found at the following locations:
- /examples/c++ - C++ examples for Gpufit
- /examples/c++/gpufit_cpufit - C++ examples that use Gpufit and Cpufit
- /examples/matlab - Matlab examples for Gpufit including spline fit examples (also requires Gpuspline)
- /examples/python - Python examples for Gpufit including spline fit examples (also requires Gpuspline)
- /Cpufit/matlab/examples - Matlab examples that only uses Cpufit
- /Gpufit/java/gpufit/src/test/java/com/github/gpufit/examples - Java examples for Gpufit
Authors
Gpufit was originally created by Mark Bates, Adrian Przybylski, Björn Thiel, and Jan Keller-Findeisen at the Max Planck Institute for Biophysical Chemistry, in Göttingen, Germany (see GitHub Project account)
