A High-Performance Implementation of a Robust Preconditioner for Heterogeneous Problemsgh-performance PDE framework DUNE [.]. The GenEO coarse space is constructed by combining low energy solutions of a local generalised eigenproblem using a partition of unity. The main contribution of this paper is documenting the technical details that are crucial to the efficiency of a high-perform

Kinetic

Hybrid Solver for Quasi Block Diagonal Linear SystemsI and OpenMP to implement preconditioned Jacobi. Specific formats for sparse matrices are exploited in order to reduce memory storage requirements. Our experiments show that communication costs are negligible, so as that speed-up and efficiency with respect to the sequential implementation are very

armistice

Parallel Adaptive Cross Approximation for the Multi-trace Formulation of Scattering Problemstering problems with composite scatterers. Individual boundary integral operators are treated independently, i.e. the boundary of every homogeneous subdomain is decomposed into clusters of elements defining a block structure of the local matrix. The blocks are distributed across computational nodes

Parallel Computations for Various Scalarization Schemes in Multicriteria Optimization Problemsis approach includes various methods for the scalarization of vector criteria, dimensionality reduction with the use of the Peano space-filling curves, and efficient global search algorithms. The applied criteria scalarization methods can be altered in the course of computations in order to better m
