DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: We present a novel trace-based analysis tool that rapidly classifies an =0AMPI application as bandwidth-bound, latency-bound, load-imbalance-bound, =0Aand computation-bound for different interconnection networks. The tool uses =0Aan extension of Lamport's logical clock to track application progress =0Ain the trace replay. It has two unique features. First, it predicts the=0Aapplication performance for many network configurations by replaying the=0Atraces only once. Second, it infers the performance characteristics =0Aof an application and classifies the application using the predicted =0Aperformance trend for a range of network configurations instead of using=0Athe predicted performance for a particular network configuration.=0AWe describe the techniques used in the tool and its design and implementation,=0Aand report our performance study of the tool and our experience with =0Aclassifying 9 applications and miniapps from the DOE Design Forward =0Aproject as well as the NAS parallel benchmarks.
