You nerd sniped me a little and I'll admit I'm not 100% sure what a reduction is but I've understood it to be a measurement of work for scheduling purposes.

A bit of googling indicates that actually you can use performance monitoring instur to generate an interrupt every n instructions. https://community.intel.com/t5/Software-Tuning-Performance/H...

Which is part of the solution. Presumably the remainder of the solution is then deciding what to schedule next in a way that matches erlang.

Disclaimer: this is based off some googling that makes it seem like hardware support the desired feature exists, not any actual working code.
