Unable to understand the difference between some keywords and functions with RandomX

Question

I am unable to understand what the reference CPU is, the SuperScaler hash program and the VM of RandomX.

How the programs are run on the RXVM.

What is the role of SuperScaler.

Answer 1

I am unable to understand what the reference CPU is, the SuperScaler hash program and the VM of RandomX.

Reference CPU: https://github.com/tevador/RandomX/blob/master/doc/specs.md#62-the-reference-cpu

SuperScaler hash: https://github.com/tevador/RandomX/blob/master/doc/design.md#34-superscalarhash

Superscalar processor: https://en.wikipedia.org/wiki/Superscalar_processor

RandomX Virtual Machine: https://github.com/tevador/RandomX/blob/master/doc/design.md#2-virtual-machine-architecture and https://github.com/tevador/RandomX/blob/master/doc/specs.md#4-virtual-machine

How the programs are run on the RXVM.

Allocate & initialize the cache, dataset and VM, then run in a function like: https://github.com/tevador/RandomX/blob/v1.1.10/src/randomx.cpp#L349-L368 (e.g. machine->run(...))
