1. A method for associating instrumentation data with a simulation model within a batch simulation farm in which a simulation client communicates with an instrumentation server to process simulation data with respect to said simulation model, said method comprising: delivering an instrumentation eventlist from said simulation client to said instrumentation server, wherein said eventlist contains instrumentation event information for said simulation model; and within said instrumentation server: computing a digital signature that uniquely identifies contents of said instrumentation eventlist as being associated with said simulation model; and in response to receiving simulation data from said simulation client, utilizing said digital signature to associate said simulation data with said simulation model.
