Recomputing With Microsoft Azure

One of the important ways in which we want to make recomputable experiments easily available is to have them be available in a variety of ways. This is why we applied for an Azure for Research grant in 2013, and were delighted to receive one: in fact we got more cloud resources than we had requested! We are also very grateful that an extension to our grant was very generously given when Ian Gent’s illness caused problems for the project.

How Do We Know the Answer Is Not 43?

recomputation.org Involved in New Data Intensive Research Institute

Today has seen the announcement of the new Institute for Data-Intensive Research (IDIR) at the University of St Andrews.

Dogfood, Dogfood, Dogfood

Since I started recomputation.org a bit over a year ago, I’ve written a number of papers with experiments in them.

Only one of them is available on recomputation.org.

Not. So. Good.

Screencast of Queens Experiment

Last night I published a screencast of me recomputing the queens experiment from [recomputation.org].

Please do watch it if you’d like to see how easy it is to recompute experiments.

Here’s a link direct to youtube if you’d rather watch it there than embedded here.

On Virtual Machines Considered Harmful for Reproducibility

This post is to summarise a couple of comments I made to a post from Titus Brown.
But I’m crossposting here
because I really want to be the kind of scientist who focusses on points made against his point of view, and
gives them air.

Our First Experiment: A Chess Puzzle

We are very pleased to announce the first experiment available from recomputation.org.

After downloading the experiment box and booting, it takes only about 1 minute to run.
It is available at http://recomputation.org/cp2013/experiment1.html.
The experiment is to confirm that the following statement is true.

Welcome to CP 2013 Authors

Lars Kotthoff and I would like to give a warm welcome to
recomputation.org to any successful authors with papers at the CP 2013 conference.
We will be giving a tutorial on recomputation at the conference, and we want to report on recomputation of as many papers from the conference as we can.

Not a Lot About Excel and Some Links

Reproducibility of computational experiments hit the headlines the other day. Instead of citing one of the many news posts about it[(e.g. this one) http://www.bbc.co.uk/news/magazine-22223190], let’s go straight to the source:
