How do you use a supercomputer?

To be honest, this post should have been written before the previous one. But as they say, better late than never. If the previous post consisted of describing the theoretical principles behind an aerodynamics simulation, this one is going to

Change of plans

So… Remember the test environment setup I was working on last time? I had to drop it last week. The PCOCC installation took me some time and a lot of patience, but it did run through at the end. Unfortunately,

Is benzene a nanotube?

Of course not, but I have input for benzene and I did the first tests of the electron density computation on this system. Before showing the results (Pretty figures!), I would like to tell you about the helical symmetry (something

Nanotube-laboratory in a computer

I spent the first few weeks at Computing Centre of the Slovak Academy of Sciences getting familiar with the nanotube code. We actually changed the goal of the project a bit. The original plan was the further development of the

Can’t `$ touch this`: Containerisation on permissioned HPC systems using Singularity

In my previous blog post, I discussed the advantages of containerisation when it comes to reproducibility. In short, if you package all of the tools necessary to run your experiments, you can ensure that in future, folk can rerun your

No internet? Let the game begin

Dear reader, I know it has been only a few days since my last post, and I am also aware that you are not used to listening (or maybe reading!) from me so often. However here, at BSC, we are

How to know if your Deep Learning Algorithm actually learned anything

Hello from Luxembourg. If you read my previous post, you may be aware that this is where I’ll be spending my summer as part of the PRACE Summer of HPC programme. The official title for the project I’ll be doing

We arrived at BSC; now what?

It was only recently that I realized this experience called SoHPC is already midway through and since it has been almost an entire month that I have been silent I decided to drop a few lines in order to give

Removing the data processing ‘bird’en with Spark

Greetings dear audience. Sorry that I’ve been a little radio-silent over the last week. I guess you could say I dropped off the radar. Read on for another riveting installation of ‘Allison’s summer of HPC’. It’s hard to believe, but

Understanding the basic principles

During my first three weeks at the Jülich Supercomputing Centre (JSC) the material was mainly introductory to many different and interesting topics. I was firstly introduced to the topic of processors. I got myself familiar with the main architecture and

Building a supercomputer in a cloud

With my second week ending here at SURFsara, I’ve learned quite a bit about the background of my project and those insights have been very interesting, so I thought I’d share them with you! On a usual supercomputer, networks and

Brief introduction​: STFC Hartree.

Much has happened since my previous post ( ) and I have been quite overwhelmed. Finally, I have found some time to evaluate the last two weeks and share my experience with you. The STFC-Hartree centre is my new

Dusting off some gold

Let’s go back, way back… The year is 2014. Pharrell Williams’ Happy is number 1 on the charts, and a former Etonian is Prime Minister of the UK. The motivating paper for my project is released: Toward the efficient use

How Is an Aerodynamics Problem Solved? From Zero to Hero in 5 Steps

This post is intended to explain, from the very basics, how to deal with aerodynamics equations, in order to then understand why HPC (High Performance Computing) systems are so relevant to this matter. My aim is that, even (and especially)

Episode 2: The fellowship of performance

Yay, the second post is finally here! You can know more about what I’ll be doing this summer and why my project is important.

This is just an overview, we will spell out the details in some future posts. Stay tuned and don’t hesitate to tell me what you think about this post and contact me if you want to discuss about the project!

Introducing a Vegan to Protein

As a vegan, I am undoubtedly familiar with protein and how important it is to our survival – even more so now that I have been studying it for my PRACE Summer of HPC Internship. More specifically, I have been
