TUTORIAL AND WORKSHOP

We’re reaching out – PETSc, the Portable, Extensible Toolkit for Scientific Computing, is one of the world’s most widely used software libraries for high-performance computational science. We’ll hold our fifth annual user meeting (third in the US), give tutorials on how you can leverage the functionality in PETSc for your research, and highlight science achievements made possible by advances to PETSc’s features and functionality – not only by the PETSc team but also by applications developers and designers of simulation packages that use PETSc.

And we’re building toward the future – addressing new ideas and new science challenges of emerging architectures, as well as issues in interoperability with complementary tools in the broader HPC software ecosystem. We’ll brainstorm about future directions such as strategies for manycore systems.

How can you contribute? – PETSc has been used both in traditional disciplines of engineering and physics and in emerging fields such as computational biology, and new work is beginning to address issues in emerging extreme-scale computing environments. We encourage you to present work illustrating your own use of PETSc. We also invite you to contribute to the future of PETSc, helping identify strategies to encapsulate algorithmic advances in state-of-the-art software, making possible more accurate, predictive simulations by scientists and engineers.

TUTORIAL THEMES

• DAE/ODE integrators: Select from many different time steppers.
• Vectors and matrices: Learn how data is distributed at scale.
• Linear preconditioners: Accelerate linear solvers.
• Nonlinear solvers: Find out how information can be reused efficiently. 
• Understanding performance: Identify performance bottlenecks quickly.

WORKSHOP THEMES

• Algorithms: Presentations on advanced algorithms that use PETSc.
• Applications: Presentations on large-scale application codes that use PETSc.
• High-performance numerical software library design.
• Future directions, including
  • new hardware architectures;
  • the “outer loop,” such as sensitivities, stochastic models, design optimization, parameter estimation, and uncertainty quantification; and
  • new programming models for HPC simulations.

INVITED SPEAKERS

• Nathaniel Collier, Oak Ridge National Laboratory
• Hannah Morgan, Argonne National Laboratory
• Ellen M. Price, Harvard University
• Richard Vuduc, Georgia Institute of Technology
