FLARE Computing Library

FLARE is a GPU-accelerated library for building spatial models on geographical grids using NetCDF file format for data input/output.

This library provides the following features:

Gridded Variables - Objects of this class include storage for gridded data along with meta-data, such as lat-lon arrays and time. This library also provides operators on gVars such as addition, multiplication etc.
NetCDF input/output streams - These are data streams that can read from and write to netcdf files, automatically handling data distributed over multiple files and interpolation of data into the desired grid.
2D Regridding (linear interpolation, coarse-graining), masking functions
Time arithmatic, vector arithmatic utilities
Initializer class - To quickly read configuration files to initialize model variables
GPU-accelerated Turbulence Engine - A synthetic turbulence generator to create spatial heterogeneity and simulate fluid flow
GPU-accelerated logistic resource dynamics - A spatial diffusible resource that grows at a logistic growth rate
GPU-accelerated versions of grid functions. Currently, the trend function has a GPU version. Other functions are under development.

Documentation

Detailed PDF Documentation can be found in the docs folder. Some sections are under preparation. Web documentation will be available soon.

Installation

You must have the following libraries installed to use FLARE.

NetCDF-C++ legacy version (v4.2)
libgsl
CUDA toolkit.

mkdir builddir lib
make LIBPATH="-L/path/to/netcdf-cxx-legacy/lib -L/path/to/cuda/lib64" INCPATH="-I/path/to/netcdf-cxx-legacy/include -I/path/to/netcdf-c/include -I/path/to/cuda/include"

then copy the libs folder to desired location
