Research Interests

• Sparse direct solvers
• High-performance computing

Selected Projects/Software

• MUMPS: MUltifrontal Massively Parallel Solver for symmetric and unsymmetric complex/real systems of sparse linear equations of the form A X = B, where A is a sparse matrix


• MUMPS 5.6.0 (April 2023) is available.
• Features include: MPI and OpenMP parallelism, low-rank compression, out-of-core, save-restore to disk, high performance, advanced pivoting for symmetric indefinite matrices, use of internal or external orderings, compressed/constrained orderings for $K K^T$ systems, distributed Schur complement, reduced/condensed RHS, multiple right hand-sides, sparse multiple right-hand sides, distributed solution, determinant, forward elimination during factorization, selected entries of the inverse, null pivot detection, parallel analysis.
• User's guide MUMPS 5.6.0 (April 2023) (in pdf format)
• Related publications
• The MUMPS Consortium is a consortium of industrial users who fund the project in exchange of a number of services, see http://mumps-consortium.org. Since January 2019, Mumps Technologies SAS is in charge of managing this consortium.
