. We are interested in the stability of three-dimensional fluidflows to small disturbances. One computational approach is to solve asequence of large sparse generalized eigenvalue problems for the leadingmodes that arise from discretizating the differential equations modelingthe flow. The modes of interest are the eigenvalues of largest real partand their associated eigenvectors. We discuss our work to develop an efficientand reliable eigensolver for use by the massively parallel...
