May 28-29 Panel Sessions

Runtime Systems Vision

Moderator: Vivek Sarkar

Panelists:

We have presented the results of the Runtime Summit, which include challenges, solutions, a set of important questions to be answered, and a vision for a runtime architecture, with major components, interfaces, and how to measure success.

This session will focus on getting feedback from selected panelists and the audience on our results. Panelists will first provide us with constructive criticism and suggestions, followed by the interaction with the audience.

Mapping and Optimization Framework

Moderator: Armando Solar-Lezama

Panelist:

Panel description. Armando we want to bring here discussions about how a high level representation is mapped and optimized to a particular platform, with as much info about automated mappings/code generation as possible. This should include Mappings, Synthesis, Optimization, and Learning

Mapping Framework Panel Summary)

Resilience

Moderator: Andrew Chien and Mattan Erez

Panelists: Kath Knobe, Sriram Krishnamoorthy, Dan Quinlan, Vivek Sarkar, Martin Schulz

The goal of this panel is to engage in a focused discussion about how resilience should reflected in the X-stack runtime abstract architecture and about what the critical research technologies are.

Simulation technology

Moderator: Shekhar Borkar/Wilfred Pinfold

Panelists: John Shalf, Jeff Vetter, Arun Rodrigues, Romain Cledat

Panel description: Simulators are tools for getting a job done. There are many jobs we can use simulators for in designing an Exascale system. First there are simulators for use in various stages of design; conceptual, functionality, final (cycle accurate). Then there are simulators for CPU, memory, network, storage, IO. Finally there are simulators to explore different machine characteristics such as power, resilience or performance. These simulators can be designed to work separately, as cooperating parts or as an integrated system simulation. In this panel we will explore the simulators in use today, the benefits and challenges of integration and the direction we should take to optimize system design and minimize effort expended on tool development.

Implications of Emerging Memory Technology to Exascale Computing

Moderator: Jeff Vetter / Xipeng Shen Panelists: to be determined

The proposed panel is intended to discuss implications of emerging memory technology (e.g., Non-volatile memory, 3D-stack memory) to the various layers in the software stack of exascale computing.
