SUMMARY:Optimization of a Lattice Boltzmann Program
DESCRIPTION:Workshop\nDiversity, Education, Hot Topics, Workshop Reg Pass\
 n\nOptimization of a Lattice Boltzmann Program\n\nZhou\n\nIn this project,
  I optimized a Lattice Boltzmann (LB) program developed internally by the 
 digital rock team at BP to simulate single-phase flow and predict permeabi
 lity of porous rocks. LB algorithm is simple to formulate and implement, a
 nd it is easily parallelizable on computer clusters. My work in this proje
 ct includes adding parallel input/output, building solid side-wall boundar
 y condition, and optimizing code runtime through improving input load bala
 nce and automatic loop vectorization. These runtime optimizations lead to 
 a 3x speedup over the current (now previous) production LB code.
