Topology Aware Scheduling Using Prometheus and Telemetry Aware Scheduler - Killian Muldoon, Intel & Tom Golway, Hewlett Packard Enterprise

The k8s default scheduler does an excellent job scheduling cloudnative workloads but the same isn’t true for performance sensitive workloads. Scheduling based on Topology of hardware resources is currently impossible due to the scheduler’s lack of knowledge of node topology. Topology Manager in kubelet aligns topology-based resource allocations from CPU and Device Manager but only after workloads are scheduled. With Observability tools becoming popular we solve this problem using Prometheus and Telemetry Aware scheduler, a scheduling enhancement framework.
The focus of this talk is Topology Aware Scheduling and we discuss how exposing cluster level topology to the scheduler using Prometheus enhances the default scheduler, empowering it to proactively use node level topology to make intelligent NUMA aware placement decisions leading to more effective cluster wide performance of workloads.
