Description: In a previous report, R. E. Newton proposed two improvements to the Staniforth-Mitchell      barotropic numerical weather prediction code. Reported here are results of performance      comparisons between the original code and an amended version which incorporates the      two improvements: a new solution routine for the eigenproblems and a direct solution of      the Helmholtz equation. It is found that the proposed improvements do reduce the      computation time, but that the new eigenproblem algorithm results in excessive round-off      error when single- precision arithmetic is used.
