In high performance computing (HPC), the importance of fast, large scale models of high fidelity are only increasing as we move towards the next frontier of exascale. Hardware/software codesign is viewed as a key methodology to reaching this end. The SST/macro toolkit provides HPC engineers the ability to explore current and future hardware/software design constraints. Instead of costly (in time and user effort) cycle-accurate simulation, macro-scale simulation can provide valuable insight into the performance of large applications. The value of these tools lies in high quality application models for increasingly complex hardware designs.
The Eiger Performance Modeling Framework generates models by applying statistical techniques from the field of machine learning on empirical performance data. While macro-scale simulation can provide a reasonable overview of system wide phenomena, Eiger can leverage data acquired from micro-scale sources to inform large scale simulations in SST/macro. Eiger provides an API and data store for aggregating data from micro-scale sources such as simulators, emulators, and runtime instrumentation.
This tutorial will present attendees with the techniques and methodologies to leverage SST/macro and Eiger for modelling large scale applications on upcoming supercomputer hardware. This presentation is geared towards domain experts and HPC hardware designers, as well as students and researchers whose work requires exploration of programming models, interaction between computation and communication, and data-driven modelling techniques for large scale systems. These tools are geared toward ease of use and rapid iteration, allowing area experts to generate verbose performance models without requiring intricate knowledge of every facet of the computing environment. This tutorial will require only a basic level of programming skill.
