The latest version of JMH tool allows to measure core to core latency using the following command:

`java -jar jmh-core-benchmarks-latest.jar -t roundtrip_latency -m quick`

Hi, thanks for the article. Can you cite which tool you use to compute/draw these heatmaps (I may have missed the link, sorry).

Do you have similar heatmaps about succesful/contented atomic read/writes across cores? Easy to obtain?

Cheers
