Process management libraries and runtime environments serve an important role in the HPC application lifecycle. This work provides a roadmap for implementing a high-performance PMIx based software stacks and targets four performance-critical areas presenting novel codesigned solutions that significantly improve application performance during initialization and wire-up at scale.
