Runtime Systems
Moderator: Vivek Sarkar
Panelists: Ron Brightwell, David Grove, Sanjay Kale, Wilf Pinfold, Kathy Yelick
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.

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.

Performance Tools and Their Interfaces for the X-Stack
Moderator: Martin Schulz (LLNL)
This panel will discuss the role of performance tools in the exascale software stacks: which tools will users expect and which questions should they address, what abstractions should they map their results to and what interfaces in the X-Stack will be available for tools to require the necessary information?
