The PETSc Community Is the Infrastructure
Mark Adams, Satish Balay, Oana Marin +13
The communities who develop and support open source scientific software packages are crucial to the utility and success of such packages. Moreover, these communities form an import…
Understanding performance variability in standard and pipelined parallel Krylov solvers
Hannah Morgan, Patrick Sanan, Matthew G. Knepley +1
In this work, we collect data from runs of Krylov subspace methods and pipelined Krylov algorithms in an effort to understand and model the impact of machine noise and other source…
The PetscSF Scalable Communication Layer
Junchao Zhang, Jed Brown, Satish Balay +7
PetscSF, the communication component of the Portable, Extensible Toolkit for Scientific Computation (PETSc), is designed to provide PETSc's communication infrastructure suitable fo…
Toward Performance-Portable PETSc for GPU-based Exascale Systems
Richard Tran Mills, Mark F. Adams, Satish Balay +11
The Portable Extensible Toolkit for Scientific computation (PETSc) library delivers scalable solvers for nonlinear time-dependent differential and algebraic equations and for numer…
Comparative study of finite element methods using the Time-Accuracy-Size (TAS) spectrum analysis
Justin Chang, Maurice S. Fabien, Matthew G. Knepley +1
We present a performance analysis appropriate for comparing algorithms using different numerical discretizations. By taking into account the total time-to-solution, numerical accur…
