When I wrote end-to-end tests for Sudocle the other day, I noticed that they ran much faster when I started my browser in non-headless mode. After some debugging, I was able to figure out that the browser I was using to run my tests (Chrome/Chromium), automatically employs a software renderer for WebGL when started headless. Since Sudocle heavily relies on WebGL, the tests could benefit a great deal from hardware acceleration.

I’ve just released the new version 5.8.0 of my scientific workflow management system Steep. One of the highlights of this version is increased fault tolerance: Steep schedulers are now able to resume the work of other crashed instances when they detect that a process chain is running but not monitored anymore. Steep 5.8.0 also includes many other new features (see details below). The version has been thoroughly tested in practise over the last couple of months.

Our paper with the title “Executing cyclic scientific workflows in the cloud” has just been released in Springer’s Journal of Cloud Computing. In this paper, we present an algorithm and a software architecture for a cloud-based system that executes cyclic scientific workflows whose structure may change during run time.

I’m a huge Sudoku fan. Today, I’m releasing the first version of my new web app called Sudocle. The app has been inspired by Cracking the Cryptic, the world’s most popular YouTube channel about Sudoku and other logic puzzles, which I can highly recommend!

I’m very happy to announce that the new version of my scientific workflow management system Steep has just been released. The new version introduces live process chain logs, improved VM management, and many other things (see complete list below). The version has been thoroughly tested in practise over the last couple of months.
