Summarized application profiling and quick network profiling

摘要

An automatic distributed partitioning system (ADPS) profiles a computer network using short term sampling to estimate minimum network latency and maximum network bandwidth. The ADPS profiles an application program to produce an application profile that summarizes inter-unit communication within the application program. Summarization of the application profile reduces overhead during profiling of the application program. The application profile is network independent, but by combining it with information in the network profile, the ADPS produces a model of the behavior of the application program on the computer network. Quick estimation of network characteristics facilitates the ADPS repartitioning the application to adjust to a different computer network or a changed computer network.
