OCaml performance in computational science: some data and code; supplement for publication

Supplement for manuscript "Nmag micromagnetic simulation tool -- software engineering lessons learned" by Hans Fangohr, Maximilian Albert and Matteo Franchin (2016). This repository contains some test programs that help investigating the performance of code emitted by the OCaml compiler (ocamlopt) for some of simple cases which are particularly relevant to numerical code. The tests are provided in separate directories. Each directory contains the OCaml version and the C++ version of the same test. Here is a list of the available directories: multidim-arrays: test accesses to multi dimensional arrays implemented (i) as regular OCaml arrays and (ii) using the Bigarray OCaml module. array-sum: test addition of two large unidimensional arrays. summation: test computation with low memory bandwidth requirements See the README files in the individual subdirectories for more details on the investigations performed and results obtained.
