Θεματικοί όροι: Àrees temàtiques de la UPC::Informàtica::Arquitectura de computadors, High performance computing, Numerical grid generation (Numerical analysis) -- Data processing, Poisson algebras, Preconditioned Conjugate Gradient, Krylov Methods, Parallel Algebraic Linelet Preconditioner, Boundary Layer Flow, Càlcul intensiu (Informàtica), Xarxes múltiples, Mètodes de (Anàlisi numèrica)
Περιγραφή: An algebraic linelet preconditioner is presented, which works in parallel regardless of the mesh’s geometry and without imposing constraints on the domain partition. It is designed to deal with highly anisotropic meshes. A key aspect of this work is developing an algorithm that generates the preconditioning matrix by purely algebraic considerations. This preconditioned is coupled to Alya, the in-house HPC multi-physics code developed at Barcelona Supercomputing Center.
