Dynamic Performance Forecasting for Network-Enabled Servers in a Metacomputing 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 rou-tines needs in terms of completion time, memory space and number of communication, as well as of current system availability. Fast relies on existing 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 inter-face are presented, as well as experimental results
