In this episode of the Let’s Talk Exascale podcast, produced by DOE’s Exascale Computing Project, the topic is PETSc—the Portable, Extensible Toolkit for Scientific Computation. It’s a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. A team within ECP is preparing PETSc/TAO for exascale […]
Video: Extreme-Scale Multigrid Components within PETSc
June 10, 2016 by
In this video from the PASC16 conference, Patrick Sanan from USi Lugano & ETC Zurich presents: Extreme-Scale Multigrid Components within PETSc. “Elliptic partial differential equations (PDEs) frequently arise in continuum descriptions of physical processes relevant to science and engineering. Multilevel preconditioners represent a family of scalable techniques for solving discrete PDEs of this type and thus are the method of choice for high-resolution simulations.”
