Assessing Job Wrapping as an Strategy for Workflow Optimization on Shared HPC Platforms
crossref(2024)
摘要
Experimenting with modern ESM inherently requires a workflow organization to handle the multiple steps comprising of, but not limited to, execution, data governance, cleaning, and coordinating multiple machines. And for climate experiments, due to long scale of the simulations, workflows are even more critical. The community has thoroughly proposed enhancements for reducing the runtime of the models, but long has overlooked the time to response, which also takes into account the queue time. And, that is what we aim to optimize by wrapping jobs, which would otherwise be submitted individually, onto a single one. The intricate three-way interaction of the HPC system usage, scheduler policy, and user's past usage is the main challenge addressed here to analyze the impact of wrapping jobs.
