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.

Visualising the World Map of Supercomputers

“The greatest value of a picture is when it forces us to notice what we never expected to see.”, John Tukey. Introduction Data visualisation continues to change the way we see, interpret and understand the world around us. But it

More on Deep Q networks

Nature cover

It’s time for another blog post apparently! Just as last time, I have decided to fill it with science! This time I will talk mostly about the “Deep Q Network” and the “Stochastic Gradient Descent” algorithm. These are all fairly

El Niño around the world

In my last post, I explained what El Niño events were about. In general, El Niño events are part of a bigger oscillation pattern in the climate of Earth called ENSO (El Niño-Southern Oscillation) that changes patterns in temperature and

Climbing higher everyday

During this summer I’m trying to get a little better every day. As a hiking enthusiast, I really love to get on track during weekends. Scottish Highlands paths seem to be slightly worse maintained and much less congested than Tatra Mountains

Shared But Hard to Use: Helping Climate Researchers Share, Discover, and Use Data

1. The Problem Sharing data among researchers is usually an afterthought. In our case, data is already shared publicly on a data repository, which is called DSpace. DSpace serves as an open-access repository for scholarly data published in various scientific

Which is the busiest node in the HPC cluster

What is a high-performance computer (HPC)? In simple terms, nowadays it is a cluster of innumerous ‘mini’ computers (nodes) interlinked by the same network. When a big calculation is submitted to the HPC, it will be fragmented into thousands of
