MUMPS: A Multifrontal Massively Parallel Solver
www.ercim.eu › publication › Ercim_News‘—’ indicates not enough memory. It is thus necessary to obtain further parallelism within the nodes near the root by partitioning these nodes among several processors. In addition, because MUMPS is designed to solve a wide range of problems including symmetric and unsymmetric problems, numerical pivoting is performed within the numerical ...
