A tool to measure memory latency between CPU cores.

Port of this github repo in rust.

Prerequisites:

Install with:

cargo install c2clat

On the command-line:

$ c2clat
 CPU    0    1    2    3
   0    0   63   27   63
   1   63    0   63   27
   2   27   63    0   63
   3   63   27   63    0

Generate a heatmap with gnuplot:

$ c2clat -p | gnuplot >heatmap.png

Limit tests to a subset of cores with taskset:

$ taskset -c 1,3 c2clat
 CPU    1    3
   1    0   27
   3   27    0
