The Advanced Technology Development and Mitigation (ATDM) subprogram addresses the technological disruptions resulting from the evolution of HPC to radically different and more complex architectures. The ATDM subprogram tackles the most critical subset of issues occurring during this period of disruptive change in HPC architectures to continue the current level of support to the Nuclear Security Enterprise mission. As part of this subprogram’s work scope, the ASC Program has engaged with the DOE Office of Advanced Scientific Computing Research to address the barriers to exascale and evolving architectures.
Next Generation Code Development & Applications
This product is focused on developing new simulation tools that address emerging HPC challenges of massive, heterogeneous parallelism using novel programming models and data management. Modern codes will be developed through co-design of applications by laboratory scientists and engineers and co-design of computer systems by computer vendors. The end product of this work is a next-generation set of simulation tools that may complement and/or replace the current set of production tools for the Nuclear Security Enterprise.
Next Generation Architecture and Software Development
This product is focused on long-term computing technology research of advanced architectures in areas such as extreme in-node parallelism. This includes efforts to mitigate disruptive effects and to allow ASC Program simulation tools to take advantage of more powerful computing resources while advancing capabilities.
Future High Performance Computing Technologies
Future High Performance Computing Technologies is focused on evaluating alternative HPC technologies after limits of current semiconductor technologies are reached (post Moore’s law era).
