Node Renumbering Strategies for Efficient Direct Methods in Selected Problems of Soil Mechanics

Original language description

This paper gives an experimental evidence of the computational and memory efficiency of standard reordering techniques available in PETSc library and their effect on the PETSc Cholesky solver performance. The sparse matrices chosen for numerical testing come from domain decomposition of the FETI type of the slope stability problem and the best QMD reordering was able to reduce the factorization time by factor up to 1000, the solve by factor up to 40, number of nonzero entries in factorized matrix by factor 30 and memory requirements by factor 25.
