Marcel van der Veer Building a small Beowulf cluster II

03-04-2018

As described in an earlier post, at home I operate a modest Beowulf type cluster for embarrassingly parallel simulation runs in batch mode. With the experience from that build, I took on building a higher-performance cluster using Debian. [Read more]

Marcel van der Veer Classical thermodynamics in a nutshell

18-11-2017

Recently I met during an event at my Alma Mater, the University of Nijmegen, my high school physics teacher. We discussed the chemistry curriculum and remarked that quite some chemistry students capture with difficulty the fundamental principles from thermodynamics. Needless to say that thermodynamics is one of those subjects that serve a chemist for a lifetime. In my humble opinion, one reason for this lack of retention may be the abstraction level in freshmen courses and that this might be improved by spending one or two introductory hours on the basic ideas of thermodynamics in a historic context.

Marcel van der Veer Building a small Beowulf cluster

01-10-2016

At home I operate a modest Beowulf type cluster for embarrassingly parallel simulation runs in batch mode. A master node controls several drones. Nodes in this cluster need no more than a server installation, but if a drone happens to have keyboard, mouse and monitor a small GUI is nice to have. This GUI should be lightweight, otherwise a desktop installation makes more sense. This page demonstrates how to set up a drone with GUI on Ubuntu Server including browser, document reader, image viewer and sound. [Read more]
