Offenes Rechnersystem mit mehreren Servern

摘要

The open computer system (SAM) with multiple servers (Ali) comprises a first client system (SCL) associated with a number of servers (AL1...ALn). This includes, at the level of each server a device for calculating the load (MCCi) at first sampling times, and a device calculating the rate at which this changes. A memory (TCAi) retains the load and the rate of change. At the level of the client (SCL) the system includes a scrutinising process (PSC) asking each server, at second sampling times, to provide the rate of change and average load. A second memory retains this for all the servers. As a result of the stored information, the client system is able to make a choice of the least heavily loaded server.
