What is Lattice-Boltzmann Method in HPC about?

This document summarizes a presentation on parallelizing lattice-Boltzmann fluid simulations using MPI. It introduces the lattice-Boltzmann method and its application to modeling magnetohydrodynamics. Performance tests show near-linear speedup from 1 to 8 processors. The implementation uses MPI_ISEND, MPI_RECV and MPI_WAIT to transfer ghost cell data between processors. Future work includes saving data in NetCDF format and load balancing the grid distribution.
