Canonical’s recipe for High Performance Computing

HPC Ubuntu tech blog

In essence, High Performance Computing (HPC) is quite simple. Speed and scale. In practice, the concept is quite complex and hard to achieve. It is not dissimilar to what happens when you go from a regular car to a supercar or a hypercar – the challenges and problems you encounter at 100 km/h are vastly ...

The Hunt for Rogue Time – How we investigated and solved the Chromium snap slow startup problem

Desktop Ubuntu tech blog

In October, we shared a blog post detailing significant snap startup time improvements due to the use of a new compression algorithm. In that article, we focused on the cold and hot application startups, but we did not delve much into the first-run setup scenario. While running our tests, we observed a rather interesting phenomenon, ...

Snap speed improvements with new compression algorithm!

Desktop Ubuntu tech blog

Security and performance are often mutually exclusive concepts. A great user experience is one that manages to blend the two in a way that does not compromise on robust, solid foundations of security on one hand, and a fast, responsive software interaction on the other. Snaps are self-contained applications, with layered security, and as ...
