Falcon: on-line monitoring and steering of large-scale parallel programs

Abstract

Falcon is a system for on-line monitoring and steering of large-scale parallel programs. The purpose of such program steering is to improve the application's performance or to affect its execution behavior. This paper presents the framework of the Falcon system and its implementation, and then evaluates the performance of the system. A complex sample application, a molecular dynamics simulation program (MD), is used to motivate the research as well as to measure the performance of the Falcon system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
