Flockuda is a predator-prey model that runs on a CUDA-enabled NVIDIA Graphics Processing Unit (GPU). The model is based on the Molecular Dynamics approach described by Lee et al. (2006), "Prey-Flock Deformation under a Predator's Attack", Journal of the Korean Physical Society, 48:S236--S240. However, no stochastic forces are currently included. Furthermore, the model implements a direct approach to force calculation, such that the computational complexity is O(N^2) where N is the number of prey.
The NVIDIA CUDA C compiler is required in order to compile Flockuda. The H5Part library is also required, since the prey and predator solution fields are written to an .h5part file. Flockuda is known to successfully compile with v9.1.85 of the NVIDIA CUDA C compiler and v1.6.6 of H5Part. Users may need to adjust the paths to the H5Part library in the Makefile.
A simulation can be set up by editing the parameters in example.cfg, then compiling and executing the code by running the following commands at the command line:
make
./flockuda example.cfg
