Dynamic Performance Forecasting for Network-Enabled Servers in a Heterogeneous Environment

This paper presents a tool for dynamic forecasting of Network-Enabled Servers performance. FAST (Fast Agent’s System Timer) is a software package allowing client applications to get an accurate forecast of communication and computation times and memory use in a heterogeneous environment. It relies on low level software packages, i.e., network and host monitoring tools, and some of our developments in computation routines modeling. The FAST internals and user interface are presented and a comparison between the execution time predicted by FAST and the measured time of complex matrix multiplication executed on an heterogeneous platform is given.
