Adaptive CPU Pinning Framework for Java

Adaptive CPU affinity framework for Java with business-aware isolation, virtual thread support, and chaos engineering integration.

Features

• Adaptive CPU binding based on workload, QPS, latency, and GC pressure
• Business-aware isolation with Spring Boot annotations
• Virtual thread support (Java 21+)
• Chaos engineering integration

Quick Start

cpu:
  pinning:
    enabled: true

@AffinityPool("my-service", cpus = {0,1,2,3})
@Service
public class MyService {
    @AdaptiveAffinity(workloadType = WorkloadType.CPU_INTENSIVE)
    public void process() {
        // Automatically pinned to optimal CPUs
    }
}

Performance & Requirements

30-50% latency reduction, 20-40% throughput improvement. CPU pin overhead: ~5μs. Benchmarks
