Falcon is a system for on-line monitoring and steering of large-scale parallel programs. The purpose of such interactive steering is to improve its performance or to affect its execution behavior. The Falcon system is composed of an application-specific on-line monitoring system, an interactive steering mechanism, and a graphical display system. In this paper, we present a framework of the Falcon system, its implementation, and evaluation of the system performance. A complex sample application -- a molecular dynamics simulation program (MD) -- is used to motivate the research as well as to evaluate the performance of the Falcon system.

Kulkarni, Sulekha Raghavendra (Georgia Institute of Technology, 2016-11-30)Practical programs share large modules of code. However, many program analyses are ineffective at reusing analysis results for shared code across programs. We present POLYMER, an analysis optimizer to address this problem. ...
