SUMMARY:Optimization of a Lattice Boltzmann Program
DESCRIPTION:Muhong Zhou (Numerical Algorithms Group, BP Center For High Pe
 rformance Computing)\n\nIn this project, I optimized a Lattice Boltzmann (
 LB) program developed internally by the digital rock team at BP to simulat
 e single-phase flow and predict permeability of porous rocks. LB algorithm
  is simple to formulate and implement, and it is easily parallelizable on 
 computer clusters. My work in this project includes adding parallel input/
 output, building solid side-wall boundary condition, and optimizing code r
 untime through improving input load balance and automatic loop vectorizati
 on. These runtime optimizations lead to a 3x speedup over the current (now
  previous) production LB code.\n\nTag: Diversity, Education, Hot Topics\n\
