About the Session
The high-performance computing landscape is experiencing unprecedented hardware diversification. With the rapid integration of complex AI frameworks, custom accelerators, and cloud-native paradigms, the HPC software stack has never been more complicated—or more critical to scientific discovery.
Join the Google Cloud Advanced Computing Community for an in-depth discussion featuring Todd Gamblin, Distinguished Member of Technical Staff at Lawrence Livermore National Laboratory and the creator of the widely adopted Spack package manager.
In this session, Todd will unpack the current state of HPC software architecture and share his vision for where it must go next. We will explore how to tame the combinatorial explosion of software dependencies, the evolving role of package management across bare-metal and cloud environments, and the strategies required to build sustainable, reproducible software ecosystems in an era dominated by AI and heterogeneous compute. Whether you are a developer compiling complex codes, a systems administrator managing massive clusters, or a researcher relying on these tools, this session will provide essential insights for navigating the future of the software stack.
