Containerization in HPC Environments: Challenges in Optimizing Performance and Security in Scientific Computing
DescriptionThe convergence of scientific computing, exascale data, and high-performance computing (HPC) has driven significant advancements across multiple scientific domains. However, the growing complexity of software stacks, coupled with the increased need for reproducibility and efficient resource management, has raised containerization as a vital solution in HPC environments.
A major challenge is the potential performance overhead introduced by containers. HPC workloads often demand direct hardware access for optimal performance, and the additional layer of abstraction provided by containers can affect computation speed and efficiency. Minimizing this overhead while preserving the advantages of containerization is essential for its adoption in performance-sensitive scientific applications. Additionally, containerization in HPC demands rigorous security measures, balancing user flexibility with system integrity and HPC center policies.
This work delves into these challenges and opportunities by examining the real-time implementation of containerization for NWCHEM (MDT) and OCP (Open Catalyst) scientific data within the Perlmutter supercomputer environment at LBNL.
