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

The Clusters of Supercomputers: The Top500 List in the Eyes of Machine Learning

1. Introduction This summer I started to make my first steps towards the field of HPC. My participation to the SoHPC program sparked my curiosity about this field and I have become willing to learn more about the world’s most

More results of the matric trifactorization!

After two exciting months, the Summer of HPC comes to an end. However, the last few weeks have been quite intense. On the one hand, Paras and I aimed to visit as many interesting places as possible, but on the other hand

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

A Recipe To Train A Machine

Hi, this is going to be my last post. I am going to introduce to you the machine learning (ML) pipeline in my project 🙂 In short, ML is a set of approaches to make data predictions using a series

The convergence between High Performance Computing and Big Data

This Summer of HPC in Bratislava is coming to it’s end. A summer which has been full of adventures and amazing experiences, meeting great people and spending a lot of time working hard on the project and learning from it.

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,

Cleaning things up

The wonderful and memorable summer, like every good thing, has finally come to an end. Thus, in this post I’ll try to wrap up things with some more remarks on the project and also some interesting pictures from our visit

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

The World of 3D Web Visualisation

The summer in Italy is not seeming to end but my stay here does. In my last post I showcased my work which was by that time almost done. From then, the looks didn’t change much, only the underlying stuff

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

Accelerating physics simulations with data science and vectorization

Last few weeks, it has been a very interesting time here at the Jülich Supercomputing Center. Unfortunately, I only have a bit more than a week to spend on these fascinating topics with the inspiring people here at the center.
