Visualising how the World’s Centre for Supercomputing Shifted over the Last Decade

1. Introduction In an age marked by data-driven knowledge, visualisation plays a major role for exploring and understanding datasets. Visualisations have an amazing ability to condense, analyse, and communicate data as if telling a story with numbers. In contrast to

Adéu, Barcelona.

The sea through the train window

Well, I’m writing this from back home in Norway after a great summer in Barcelona! This time, I’ve decided not to write so much hard scientific stuff as before. For that, I refer back to my two previous posts one on

Unfinished creative work?

Two months of this summer have passed by very fast. It is the end of my Summer of HPC project and thus the end of my adventure in Scotland. However, is it the end of this project for sure? I’m

Automated Extraction of Metadata from Climate Simulations: Project Wrap-Up

1. Introduction As the project intensively included the processing of NetCDF datasets, this section serves as a brief background to the NetCDF format and its underlying data structure. NetCDF stands for “Network Common Data Form”. The NetCDF creators (Rew, Davis,

Building a reliable model from just a few observations

Welcome to my final blog post on the PRACE SoHPC website! First, I will show you a trick I used for building an accurate model from few data observations. Then I will  introduce the video presentation that summarises my work

An Interactive Visualisation to Explore the Top500 List

1. Introduction Among many definitions of visualisation, I prefer when perhaps it was ideally described as the transformation of the symbolic into the geometric (McCormick, 1987). In this sense, visualisation methods are increasingly embraced to explore, communicate, and establish our

The best of both worlds

comparison between NumPy, Cython and Cython with the OpenCL solver

Sometimes, rejecting unfeasible ideas early enough is a crucial step towards actually solving a problem. In my quest to speed up the ocean modeling framework Veros, I considered the option of restructuring the existing pure Python code in order to

The end, or just another beginning?

As summer ends, I can’t help but rememb Jim Morrison (The Doors) singing “this is the end, my only friend, the end…”. This post also represents an end. It is the end of my Summer of HPC project and hence
