SUMMARY:HyperQueue: Overcoming Limitations of HPC Job Managers
DESCRIPTION:Posters, Research Posters\n\nHyperQueue: Overcoming Limitation
 s of HPC Job Managers\n\nBöhm, Beránek, Cima, Macháček, Jha...\n\nIn 
 recent years, HPC workloads and communities have undergone substantial par
 adigm shifts. There is an increasing amount of users that want to leverage
  HPC clusters to execute many simple and embarrassingly parallel tasks as 
 easily as possible. Due to the limitations of traditional HPC job managers
 , however, these users must often resort to manual aggregation of tasks in
 to a smaller number of jobs to reduce job manager overhead. This approach 
 is both labour-intensive and inefficient, as it lacks dynamic load balanci
 ng required to fully utilize computational nodes with tens or hundreds of 
 cores. We introduce HyperQueue, a task scheduling runtime that can execute
  a large amount of tasks on top of an HPC job manager by automatically agg
 regating tasks into jobs and dynamically load balancing them across all al
 located nodes and CPU cores. HyperQueue is an open-source tool that is des
 igned for ease of use and deployment.\n\nRegistration Category: Tech Progr
