Parallel Frontal Solvers for Large Sparse Linear Systems
- COMPUTERS IN CHEMICAL ENGINEERING
, 2003
"... Many applications in science and engineering give rise to large sparse linear systems of equations that need to be solved as efficiently as possible. As the size of the problems of interest in-creases, it can become necessary to consider exploiting multiprocessors to solve these systems. We report o ..."

Multipole-based preconditioners for large sparse linear systems
, 2003
"... Dense operators for preconditioning sparse linear systems have traditionally been considered infeasible due to their excessive computational and memory requirements. With the emergence of techniques such as block low-rank approximations and hierarchical multipole approximations, the cost of computin ..."
