  abstract =	 { Recently, industry has begun investigating and
                  moving towards utility computing, where
                  computational resources (processing, memory and I/O)
                  are availably on demand at a market cost. On-demand
                  access to computational resources enables
                  fine-grained resource allocation for web-based
                  applications, e.g., the possibility of provisioning
                  for a minimum workload while allowing the rental of
                  additional resources for unexpected workload
                  changes. However, renting additional resources
                  relies on the ability to quickly and accurately
                  estimate the value of the resource. This paper
                  introduces CARVE: a Cognitive Agent for Resource
                  Value Estimation. CARVE is a machine-learning based
                  approach that learns to predict the change in system
                  value of having more or less system resources. Using
                  only low-level statistics and with no custom
                  instrumentation of the operating system or
                  middleware, CARVE is able to make informed decisions
                  about the return on investment of physical memory
                  when implemented and evaluated on a partitioned
                  system running a multi-partition, multi-process
                  distributed benchmark.  We show that CARVE is
                  competitive with static choices of computing
                  resources over a variety of test workloads and also
                  has the ability to outperform all static
                  configurations.  },
