On March 29th, 2024, a backdoor was discovered in xz-utils, a suite of software that
Example of how to capture CPU counters with ETW on Windows, perf on Linux or kperf on Apple.
Using ETW needs somewhat recently updated Windows 10 or 11. Not sure about exact version.
Currently tested on:

| Load three arrays (x, y and z) in SoA order, repack them and store them in AoS order. | |
| Strategy: each warp permutes its load lane with: | |
| (rowNum + (laneId() * 3)) & 31 | |
| This will convert SoA into AoS but with x/y/z staggered across rows of registers. |
