In a High Performance Computing infrastructure, it is particularly difficult to master the architecture as a whole. With the physical infrastructure, the platform management software and the users' applications, understanding the global behavior and diagnosing problems is quite challenging. And it is even more true in a petascale context with thousands of compute nodes to manage and a high occupation rate of the resources. A global study of the platform will thus consider the Resource and Job Management System (RJMS), the File System and the Applications triptych as a whole. Studying their behavior is complicated because it means having some knowledge of the applications requirements in terms of physical resources and access to the File System. In this presentation, we propose a first step toward an experimental approach that mix the use of Jobs Workloads patterns and File System access patterns that, once combined, will give a full set of jobs behaviors. These synthetic jobs will then be used to test and benchmark infrastructure, considering the RJMS and the File System.

Application Performance Modeling on Petascale and Beyond
Performance modeling of parallel application is gaining more importance. It can not only help to predict scalability and find performance bottlenecks but it can also help to understand trade-offs in the design space of computing systems and drive hardware-software co-design of future computing systems. We will discuss established performance modeling techniques and propose a mixed approach to analytic application performance modeling. We then discuss open problems and possible future research directions.
