Abstract

High-end servers that can be partitioned into logical subsystems and repartitioned on the fly are now becoming available. This development raises the possibility of reconfiguring distributed systems online to optimize for dynamically changing workloads. This paper presents the initial steps towards a system that can learn to alter its current configuration in reaction to the current workload. In particular, the advantages of shifting CPU and memory resources online are considered. Investigation on a publically available multi-machine, multi-process distributed system (the online transaction processing benchmark TPC-W) indicates that there is a real performance benefit to reconfiguration in reaction to workload changes. A learning framework is presented that does not require any instrumentation of the middleware, nor any special instrumentation of the operating system; rather, it learns to identify preferable configurations as well as their quantitative performance effects from system behavior as reported by standard monitoring tools. Initial results using the WEKA machine learning package suggest that automatic adaptive configuration can provide measurable performance benefits over any fixed configuration.
