Despite the revolutionary impact of GPU computing power on various computational tasks, challenges emerge when trying to efficiently utilize these architectures for the solution of large nonlinear systems of partial differential equations, highlighting the need for tailored algorithms.

In this talk, Senior Researcher Stefano Zampini will discuss recent developments towards exploiting GPUs with the Portable and Extensible Toolkit for Scientific Computing (PETSc), an award-winning software for the numerical solution of large systems of nonlinear and time-dependent partial differential equations.

The focus will center on diverse components essential to PDE solver construction, encompassing Krylov methods, direct solvers, preconditioners, multi-GPU communications, and distributed sparse matrix-matrix multiplications. The objective is to furnish the audience with valuable insights into attainable and realistic performance expectations.
