Today's simulations often need advanced software tools to manage the complexities associated with sophisticated geometry, mesh, and field manipulation tasks, particularly as computer architectures move toward the petascale. In this tutorial, we will teach participants about a suite of such tools specifically designed for parallel computation by the Center for Interoperable Technologies for Advanced Petascale Simulation (ITAPS). We start with an overview and introduction of our technology development philosophy which is that such services can be provided as libraries that can be used with minimal intrusion into application codes. We briefly describe several available services including dynamic partitioning, mesh adaptation, mesh quality improvement, and front tracking. Underlying these services are a common data model and interfaces that are key to providing uniform access to all tools. We will teach attendees basic use of the interfaces through simple examples and provide advice on best practices for use of ITAPS software. NOTE: Hands-on tutorial: Attendees must bring laptops with ssh capabilities to log into the hands-on machines.
