\section{BasicUtils}

This directory contains some of the lowest level basic computer science routines within {\nek}.  
 The directory currently contains the following:

We have used {\bf bold} to denote (as examples) routines at our used throughout {\nek}.  They are in this sense ``fundamental''.
Note that this list includes input/output routines (e.g. FieldIO and H5), partitioning (e.g. Metis) and Threading (e.g. Thread and ThreadBoost).
