HPSF Conference 2025

The National Supercomputing Mission (NSM) advances India’s research by providing HPC infrastructure across institutions. However, managing software on diverse HPC systems is challenging due to hardware variations, dependencies, and version control.

Spack, a flexible package manager, addresses these issues by enabling seamless software deployment and dependency management across clusters. This study examines Spack’s implementation on 17 NSM HPC systems, improving software availability and consistency.

Spack simplifies this through customized installations, automated dependency handling, and reproducible builds, ensuring compatibility.

Implementation involved a centralized repository, automated builds, user training, software optimization, and continuous refinement. This improved research productivity, reduced support overhead, and standardized environments.

Key benefits include reproducibility, faster issue resolution, and better collaboration. Future plans involve expanding Spack repositories, integrating containers, automating updates, and training. This presentation covers our implementation, challenges, and best practices.
