HPSF Conference 2025

This talk presents our implementation of a build cache of pre-optimized HPC applications using Spack. By implementing architecture-specific enhancements for both x86 and ARM platforms during the build process, we created a set of stacks of optimized software accessible through build caches. Using application builds from the cache, users can reduce compute resource requirements without requiring specialized tuning expertise.
We'll demonstrate how teams can quickly deploy HPC clusters using these stacks and discuss the substantial advantages compared to building from source. We'll present comparisons to traditional builds, showing significant time-to-solution improvements. This work represents a step toward enabling the HPC community to focus on scientific discovery rather than software compilation and tuning.
