CudneLB - the templated version

CudneLB is a MPI+CUDA or MPI+CPU high-performance CFD simulation code, based on Lattice Boltzmann Method.

It provides a clear interface for calculation of complex physics, and implementing new models.

Installation

Dependencies

You'll need:

• R
• packages for R: optparse, numbers, rtemplate, gvector, polyAlgebra
• nVidia CUDA (if you want to use GPU)
• python, numpy (if you want to use the integrated python interpreter)
• python, python and R package: rPython (if you want to develop a model using python in place or R)
• MPI (e.g. OpenMPI)

You can install lot of these with the tools/install.sh script (if you are not afraid of running a script with sudo):

sudo tools/install.sh cuda 6.5-14
sudo tools/install.sh r
sudo tools/install.sh openmpi
     tools/install.sh rdep
sudo tools/install.sh python-dev
     tools/install.sh rpython

The install.sh script is designed to work on Ubuntu (e.g. on the Travis-CI VMs). You can install the sudo parts by yourself, and use script to install R packages: rdep and rpython.

Compilation

This should work:

make configure
./configure --enable-double --enable-graphics --with-cuda-arch=sm_20
make d2q9

Usage

This should also work:

CLB/d2q9/main example/karman.xml
