What are cores, processors and nodes?

In this manual, the terms core, processor and node will be frequently used, so it’s useful to understand what they are. Modern servers, also referred to as (worker)nodes in the context of HPC, include one or more sockets, each housing a multi-core processor (next to memory, disk(s), network cards, . . . ). A modern processor consists of multiple CPUs or cores that are used to execute computations.
