We use the MIAMI. Performance modeling framework that utilizes Intel's PIN (binary instrumentation tool). To collect and categorize an application's instruction mix. The memory bandwidth tool utilizes PAPI. And measures the read and write bandwidths for a designated portion of the application. Is a lightweight profiling library for MPI applications. It is used to collet basic communication characteristics (point-to-point and collective calls) as well as the communication topology. Design based on HTML5 UP.

Hence, we believe that it is essential to quantitatively measure, project, and prioritize the resource and feature requirements of our anticipated workloads on such extreme-scale systems. The Oxbow toolkit is a collection of tools to empirically characterize application behaviours along a critical set of dimensions namely computation, communication, memory capacity and access patterns.
