kandi X-RAY | core-latency Summary

core-latency is a C++ library typically used in Testing, Performance Testing applications. core-latency has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

A simple tool for measuring latency between CPU cores. Execute make test command to run the benchmark. Requires Linux with a C++11 compiler (tested with gcc) and boost libraries. Note that measured latencies are for full roundtrip between two cores. Divide them by two to get actual time needed to fetch data from another core. Latencies are commutative so only one measument is displayed for each core pair.

QUESTION

Core latency testing ARMv8.1

Asked 2021-Apr-30 at 09:51

There is an interesting article about ARM8.1 Graviton 2 offering of AWS. This article has tests for CPU coherency where I am trying to repeat.

There is C++ code repo in GitHub named core-latency using Nonius Micro-benchmarking.

I managed to replicate the first test without atomic instructions using the command below to compile:

...

ANSWER

Answered 2021-Apr-30 at 09:51

After doing some more experiments, I found the problem. In the code snippet below are the steps:

making a comparison first (if state equals Ping)
calling the class method set to do an atomic store operation.
