We show that a certain matrix norm ratio studied by Parlett has a supremum that is O(&) when the chosen norm is the Frobenius norm, while it is O(1og n) for the 2-norm. This ratio arises in Parlett's analysis of the Cholesky decomposition of an n by n matrix.

In this study, artificial compressibility method and virtual flux method were implemented on GPUs. Because GPUs are recognized as massively parallel computers, DP-LUR was employed as time integration method. In spite of slow convergence characteristics of DP-LUR, calculation by the coupling of DP-LU
