Introduction

When performing lots of IO, the speed of writing data to disk can be crucially important for performance. Writing data depends on many factors: the type of filesystem being written to, the bandwidth to that filesystem, the IO method used for writing, and the selection of processors which write data.

This thorn provides benchmark tests for comparing different platforms and options, and ultimately results for to compare against. The thorn is very simple, it declares 100 3D grid functions, and provides parameter files to test IO with these grid functions. Currently the tests are all for checkpointing the grid functions.
