Improvements to the structural simulation toolkit

Abstract

Designing supercomputer architectures and applications is becoming more difficult because of their increased size and complexity, because of new technologies, and due to new constraints such as power and thermal limits. The Structural Simulation Toolkit (SST) is an architectural simulation framework designed to assist in the design, evaluation, and optimization of High Performance Computing (HPC) architectures and applications. Its initial release included a parallel simulation core with a number of system component models. The SST has been expanded and improved in a number of ways. New memory, network, and processor models have been added, as well as new high-level system simulation capabilities. Also, scalability results are presented.
