Query: Revisiting Performance of BiCGStab Methods for Solving Systems with
  Multiple Right-Hand Sides   The paper discusses the efficiency of the classical BiCGStab method and
several of its modifications for solving systems with multiple right-hand side
vectors. These iterative methods are widely used for solving systems with large
sparse matrices. The paper presents execution time analytical model for the
time to solve the systems. The BiCGStab method and several modifications
including the Reordered BiCGStab and Pipelined BiCGStab methods are analyzed
and the range of applicability for each method providing the best execution
time is highlighted. The results of the analytical model are validated by the
numerical experiments and compared with results of other authors. The presented
results demonstrate an increasing role of the vector operations when performing
simulations with multiple right-hand side vectors. The proposed merging of
vector operations allows to reduce the memory traffic and improve performance
of the calculations by about 30%.
