SUMMARY:Modeling the Next-Generation High Performance Schedulers
DESCRIPTION:Focus Session\n\nModeling the Next-Generation High Performance
  Schedulers\n\nTaufer\n\nHigh performance computing (HPC) resources and wo
 rkloads are undergoing tumultuous changes. HPC resources are growing more 
 diverse with the adoption of accelerators; HPC workloads have increased in
  size by orders of magnitude. Despite these changes, when assigning worklo
 ad jobs to resources, HPC schedulers still rely on users to accurately ant
 icipate their applications’ resource usage and remain stuck with the decad
 es-old centralized scheduling model.\n\nIn this talk we will discuss these
  ongoing changes and propose alternative models for HPC scheduling based o
 n resource-awareness and fully hierarchical models. A key role in our mode
 ls’ evaluation is played by an emulator of a real open-source, next-genera
 tion resource management system. We will discuss the challenges of realist
 ically mimicking the system's scheduling behavior. Our evaluation shows ho
 w our models improve scheduling scalability on a diverse set of synthetic 
 and real-world workloads.\n\nThis is joint work with Stephen Herbein and M
 ichael Wyatt  at the University of Delaware, and Dong H. Ahn, Todd Gamblin
