Abstract

Supercomputers have batch queues to which parallel jobs with specific requirements are submitted. Commercial schedulers come with various configurable parameters for the queues which can be adjusted based on the requirements of the system. The employed configuration affects both system utilization and job response times. Often times, choosing an optimal configuration with good performance is not straightforward and requires good knowledge of the system behavior to various kinds of workloads. In this paper, we propose a dynamic scheme for setting queue configurations, namely, the number of queues, partitioning of the processor space and the mapping of the queues to the processor partitions, and the processor size and execution time limits corresponding to the queues based on the historical workload patterns. We use a novel non-linear programming formulation for partitioning and mapping of nodes to the queues for homogeneous HPC systems. We also propose a novel hybrid partitioned-nonpartitioned scheme for allocating processors to the jobs submitted to the queues. Our simulation results for a supercomputer system with 35,000+ CPU cores show that our hybrid scheme gives up to 74% reduction in queue waiting times and up to 12% higher utilizations than static queue configurations.
