MJ Rutter's Computing Page

This page contains computing-related stuff produced by me. Those searching for evidence that I have a life outside of computing need to search elsewhere. I may enjoy a schizophrenic existance as mjr and mjr19, but my email address is always the latter. The correct University (not Departmental) domain is not hard to guess.


Notes on the integration of 1D functions with sharp peaks (PDF) (Feb 2014).

Notes, benchmarks and sources for Linpack in Fortran, C, python and Java (Jan 2016).


A separate page now exists for my notes on CASTEP.


Those programs which I have written and distribute fairly freely, which include bmp2eps, psimages, eps2gif and check2xsf, are all found on MJR's Software Page.

Notes on IT topics

These notes are taken from TCM's intranet, and may be useful for a wider audience.

MPhil/CDT Lectures

I have lectured on both MPI and Computer Architecture for the Centre for Scientific Computing at the Cavendish. They have some on-line course material.

One-off Graduate Lectures

These are generally more fun. Local users can find them on the relevant bit of TCM's computing pages, with a few being available on the above MPhil/CDT page.

Some older ones include:

However, beware typos and the lack of accompanying voice-over!

Part II Computational Physics

A one-off attempt to teach Fortran 90 to over a hundred undergraduates some while ago.

The following handouts may be freely used for individual learning (or entertainment). I am unaware that anyone claims copyright on the images, or that anyone other than myself can claim copyright on the text.

An example of using LaTeX to write a report was given, for which one needs this file and this one. (You will need to persuade your WWW browser to download these files, rather than viewing them.)

C and Fortran

My infamous C vs Fortran document. Yes, I should probably update it to cover C99, F2003, etc.

An Introduction to UNIX

Everyone has to write one once. So this is mine.
