ThreadPinning.bench_core2core_latency — Function

bench_core2core_latency([cpuids; nbench = 5, nsamples::Integer = 100, mode::Symbol = :min])

A tool for measuring core-to-core latency (i.e. inter-core latency) in nanoseconds.

The measured latencies correspond to a full roundtrip between two cores. Divide them by two to obtain an estimate for the time needed to fetch data from another core.

Important: At least two Julia threads are required (julia -t2)!

Refs: Largely inspired by rigtorp/c2clat and ajakubek/core-latency.
