The present disclosure provides an apparatus for analyzing trace information. The apparatus includes one or more storage devices that store a set of instructions, and one or more processors. The one or more processors are configured to execute the set of instructions to cause the apparatus to: obtain, from servers, processor instruction traces corresponding to workloads performed by the servers; generate address traces based on the processor instruction traces; and perform a workload analysis in accordance with the address traces to model resource demands of the workloads.
