Automation of high-fidelity simulations on DoD HPCs – Weapons Effects Software

As a small business, Karagozian & Case, Inc. (K&C) is aware of the challenges associated with using high-fidelity physics-based (HFPB) software on HPC systems. Learning to use new computational software often presents significant challenges due to the overhead associated with understanding input files, command line interfaces, and other technical intricacies. This difficulty is compounded when working with high-performance computing systems, which require a deep familiarity with their specific operational protocols.

In the weapons effects analysis community, many analysts utilize locally run engineering tools which may provide acceptable solutions in short timeframes but are prone to limited ranges of applicability. It is often the cause however, that these problems require a higher level of model fidelity to accurate capture challenging physics. Analysts may not be familiar with the specific high-fidelity tools necessary to solve these types of problems, may lack the time needed to generate models, or be unfamiliar with this class of tools as whole. To address this gap, a general-purpose toolkit for modeling with high-fidelity has been developed and demonstrated, which seeks to mitigate these challenges and make HFPB tools accessible to non-experts. This work has been completed under contract with Air Force Research Laboratory (AFRL).

K&C along with AFRL have demonstrated that the barrier to using high-fidelity software on HPC systems can be lowered by enabling users to set up simulations across various software platforms without needing to directly interface with the complex high-fidelity codes, of HPC systems. This solution streamlines complex analysis, allowing users to run high-fidelity simulations effortlessly, significantly reducing the learning curve and enhancing productivity. This presentation will discuss some of our initial benchmarking and challenges uncovered in course of developing this high-fidelity code interface on both K&C’s in-house cluster and the DoD HPCs.
