Gpufit

Levenberg Marquardt curve fitting in CUDA.

The manuscript describing Gpufit is now published in Scientific Reports.

Quick start instructions

To verify that Gpufit is working correctly on the host computer, go to the folder gpufit_performance_test of the binary package and run Gpufit_Cpufit_Performance_Comparison.exe. Further details of the test executable can be found in the documentation package.

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 Gpufit library may be found online (latest documentation), and also as a PDF file in the binary distribution of Gpufit.

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.
