GPU support for sparse matrix calculations in PETSc,
with applications to nonlinear Stokes
D. Karpeev, 2010
Mathematics and Computer Science Division Argonne National Laboratory, Argonne, USA
Many geophysical phenomena (matle convection, glacier dynamics) are described by nonlinear
Stokesian fluids coupled to various thermodynamic quanti-ties. Linearization leads to variable coefficient
linear Stokes systems, which can exhibit poor convergence in absence of effective preconditioners. The
emergence of GPU-based architectures offers dramatic hardware acceleration of many scientific
computation tasks. The-refore it is natural to try to take advantage of GPU acceleration for many sparse
matrix calculations, inclu-ding Stokes systems. While achieving peak performance on sparse matrices is
usually a challenge, we fo-cus on enabling GPU support within one of the most popular sparse linear
algebra and PDE library: PETSc (Portable Extensible Toolkit for Scientific computation). In this talk we will
discuss our approach to enabling GPU acceleration for sparse matrix calculations, pre-conditioning, and
the implications for Stokes solvers.
