Microbenchmarks

Microbenchmarks should isolate a single variable at a time.

  • Ping-pong latency across message sizes
  • Bandwidth sweep with fixed concurrency
  • Active message throughput with handler instrumentation

Reporting template​

  • Topology: node count, fabric, oversubscription
  • Configuration: CPU pinning, interrupt moderation
  • Results: median, p95, and p99 latency
