About this opportunity:
Control-plane software — from Layer 3 (L3) traffic control in mobile networks to microservice-based control planes in telecom and cloud — behaves very differently from the compute-heavy workloads common in CPU benchmarking (e.g., SPEC CPU, HPC, ML training). These workloads are typically front-end and memory-system bound rather than compute bound: low IPC, high branch mispredictions, large instruction footprints causing L1-I/iTLB misses, and pointer-chasing that stalls the back end. CPU microarchitecture is often tuned using representative benchmarks, but this workload class is underrepresented in open suites because real control-plane applications are large, proprietary, and hard to deploy. The result is a genuine gap: there is no open benchmark that faithfully reproduces the microarchitectural behavior of large control-plane software.
What you will do:
The goal is to characterize the microarchitectural behavior of a large control-plane application and build an open-source, configurable benchmark proxy that reproduces it — providing a shareable, non-proprietary tool for CPU architecture exploration. The work will include:
