HashiCorp Nomad 1.1 introduces several resource control features to improve efficiency and performance, including memory oversubscription, reserved CPU cores, and improved UI visibility into resource utilization. Memory oversubscription allows job authors to set two separate memory limits: a reserve limit for typical usage and a max limit for maximum usage, minimizing unused cluster memory. Reserved CPU cores enable latency-sensitive workloads to reserve entire CPU cores, improving performance and reducing sharing issues. The Nomad 1.1 UI features updates, including exposure of reserved resources and per-task breakdowns on allocation utilization charts, helping operators better understand resource utilization and optimize their clusters.
