Welcome

Presenter: Scott Lathrop, Blue Waters, NCSA

Keynote

Presenter: Paul Messina, Argonne National Laboratory

Abstract:

Exascale Computing is Around the Corner – How different will it be from Petascale?

The U.S. Department of Energy established in 2016 the Exascale Computing Project (ECP) -- a joint project of the DOE Office of Science (DOE-SC) and the DOE National Nuclear Security Administration (NNSA) -- that will result in an exascale ecosystem and prepare mission critical scientific and engineering applications to take advantage of that ecosystem.

This presentation will describe the goals of the ECP, its plans for achieving them, the challenges to be overcome, and current plans for the software ecosystem.

Introduction to MPI

Presenter: Kenneth Raffenetti and Yanfei Guo, Argonne National Laboratory

Abstract:

The Message Passing Interface (MPI) has been the de facto standard for parallel programming for nearly two decades now, and knowledge of MPI is considered a pre-requisite for most people aiming for a career in parallel programming. This is a beginner-level tutorial aimed at introducing parallel programming with MPI. This tutorial will provide an overview of MPI, its offered features, current implementations of MPI, and its suitability for parallel computing environments. Together with a brief overview of MPI and its features the tutorial will also discuss good programming practices and issues to watch out for in MPI programming. Finally, several application case studies, including examples in nuclear physics, combustion, and quantum chemistry applications, and how they use MPI, will be shown.

Advanced MPI

Presenter: Pavan Balaji and Abdelhalim Amer, Argonne National Laboratory

Abstract:

The Message Passing Interface (MPI) has been the de facto standard for parallel programming for nearly two decades now. However, a vast majority of applications only rely on basic MPI-1 features without taking advantage of the rich set of functionality the rest of the standard provides. Further, with the advent of MPI-3 (released September 2012), a vast number of new features are being introduced in MPI, including efficient one-sided communication, support for external tools, non-blocking collective operations, and improved support for topology-aware data movement. This is an advanced-level tutorial that will provide an overview of various powerful features in MPI, especially with MPI-2 and MPI-3.
