【Title】 Collaboration on Research for Resource Management and HCI for Exascale Computing Systems

【Abstract】Significant scientific challenges in areas such as material science, biology, medicine, climate modeling, high energy physics, earth sciences, and engineering design will require exascale computing (1018 operations per second). Exascale systems will involve a massive hardware base that consists of processors, memories, and communication channels. Within each of these categories, performance may vary from device to device, and, furthermore, for a given device, performance can vary quickly over time due to factors such as voltage/frequency scaling to manage electrical power and heat levels, process variations, and runtime component failures. Also, the workload to be executed will consist of tasks of different computational needs (e.g., compute-intensive, memory-intensive, hard/soft deadline-oriented) that may vary over time. As a result, exascale systems will be dynamically heterogeneous, and therefore difficult to manage.

The main problem we propose to address is how to manage resources in such a large, complex, failure-prone, and power hungry environment. Other problems we wish to examine are: 

HCI (such as Interactive computational steering and visualization); 

Simulation environment to analyze and predict performance; 

Impact of emerging technologies (such as photonics and 3D integrated circuits); 

Programming models: how to best program different levels of the system and programming methods designed for particular important problem domains.
