We present a parallel bisection mesh refinement algorithm based on ALBERT( Adaptive multi-Level finite element toolbox using Bisection refinement and Error control by Residual Techniques). The goal is to develop a parallel adaptive finite element code suitable for distributed memory parallel computers or PC clusters. An overview on the basic strategy for the parallelization of ALBERT is given. Issues on the parallel mesh refinement are addressed. A modified mesh refinement algorithm,which can be implemented efficiently on distributed memory parallel computers, is proposed and its properties are discussed.Numerical experiments with parallel bisection mesh refinement algorithm are shown.
