Hi,

I am updrading my main computer with a new Ryzen 7 9700X, witch supports AVX-512. I know that this project added AVX-512 some time ago for increased performances, however one member on the L'Alliance Francophone's forum said in a recent discussion that he saw somewhere that it has since been dropped for Asteroids@Home.

Is it true? And is there a way to know what instructions a task is using?

No, it hasn’t been dropped. We’ve transitioned to a single universal binary that detects available instructions at runtime and selects the optimal one based on your CPU’s capabilities.

You can verify which version was used by checking the task details, for example:
