A Model Transformation Tool: PMIF+ to QNAP

Abstract

An extension to the Performance Model Interchange Format (PMIF+) to move models among tools has been recently introduced.The original PMIF was limited to models solvable with efficient, exact solution methods such as mean value analysis and product form solutions.The extensions allow models with features that require simulation or analytical approximation solutions, such aspassive resources, workloads that fork into multiple concurrent workloads, etc.This paper presents a tool for the automated transformation from PMIF+ to Qnap, and explains some of the challenging transformations required by the new PMIF+ features.
