Overview of UVA HPC

Terminology

Node

A node is the basic building block of a cluster. Nodes are a type of computer called a server.
They generally have more power than a typical computer, and they may have specialty hardware like graphical processing units.

Two types of nodes:

• Head Node – a server used for logging in and submitting jobs.
• Compute Node – a server that carries out the computational work.

Core

A core is an individual processor on a computer. The cluster’s nodes have many cores (typically 40 each).

Memory

Memory refers to the random-access memory on a node.

Storage

Storage refers to the disk storage visible from a node.
