Has the rain stopped yet?

Indeed, as the summer comes to an end I realize I had a lot of rain – both here in Scotland and on my computer screen. My project was to develop a weather visualisation application which will be used at

The need for speed

Imagine for a second the following: You are given access to one of the fastest supercomputers on Earth, if not the Universe! You are given a desk in an institute in the middle of pretty much nowhere, you are granted

The wonders of the subatomic world: tiny particles and huge computers.

Note: On monday I started working on the PRACE Summer of HPC project called: Mixed precision linear solvers for lattice QCD. Since I think that most people don’t know about the subject I will write this post to tell you

Ambra Abdullahi Hassan

Ambra is a lovely, fun Italian girl of 24 years. Actually while her mom is Italian her dad comes from Somalia. Unfortunately she does not speak Somalian yet, nor has she been there — something she certainly wants to change in the future. Ambra

Final Reports on Summer of HPC

We have now reached the last week of the internship and I have just completed my final report. Summer of HPC has been a great experience. I learned a lot during the last two months and am pleased to have

The Fast Multipole Method: A Coulomb solver for the masses

There is time for laughs and there is also time for being serious and getting things done. In this blog post I would like to summarize what I have learned about the Fast Multipole Method during this programme. This theoretical

Two months later…

The summer of HPC has come to an end and I have the best impressions. Let’s have a summary of these couple months. The summer started with a kick off meeting in Barcelona. Sunny weather and interesting lectures for 5

How to thrive at Jülich in a nutshell

If you are here because you have survived to one hard month at the JSC, A.K.A. Jail for Students of Computer Science. You should be proud, but now it is not the time for bragging, you are still at the

If you like history then you’ll love Italy!

This time more about my whereabouts in August of 2015. During the summer time, especially in August, Italy is on vacation. Many people go to the seaside or retreat to the more fresh climate in the mountains. The consequence is

Visualisation of FFEA tool results

Hi all, have you noticed that it is end of summer? This summer was so crazy fast, that I almost didn’t notice. Now it is time to explain to you what I have done during the last two months. Don’t

Numerical Algorithms in LQCD

Here I will attempt to explain some of the more technical numerical aspects as to the algorithms being used in tmLQCD and some other interesting things about QCD. A computationally significant part of Lattice Quantum Chromodynamics is the solving of

Zagreb, Vienna, OpenFoam vs ANSYS

I’ve had a busy and fun couple of weeks. After weeks of wrestling with OpenFOAM I finally got some results comparable to experiment and the commercial CFD software ANSYS. As usual, I’ve been traveling on weekends whenever possible. First the

A (hopefully) gentle introduction to lattice QCD

As I have mentioned in my previous blog posts, my Summer of HPC project is optimizing software for lattice quantum chromodaynamics computations. Since this probably doesn’t ring a bell for someone who has not studied physics, I will try to provide

Nothing more equal than two parallel lines.

There is nothing more equal than two parallel lines- hence why we have two parallel lines as a sign of equality ‘=’.  How is this related to programming? This particular fact isn’t, however we do use the concept of ‘parallel’

Docking in BSC

Until now everything ran quite quickly. I still can not believe that the first month has already passed. So far it has been the most important working experience in my life. I liked everything in Barcelona because it reminds me of

“ARCHER Challenge” sneak peek

Since we are heading towards the end of our summer school I would like to give you a small preview of my project, the name of which is “ARCHER Challenge”, named after the UK National Supercomputing Service, located a few

SUMMER of HPC

I know we’re supposed to not care how it works as long as it works. But last Monday we decided to throw caution to the wind and went down into Salomon’s layer (room where they keep the supercomputer). This is

Hola Barcelona!

HPC’s introductory week in Barcelona ended up with beautiful pictures of young team-spirited researchers who, despite the difference of their fields of study they, all had something in common: they were ready to disperse throughout the world in order to

A picture is worth a thousand thousand tiny numbers.

This week I decided to talk a bit more about my project. Here at IT4Innovations they have innovated a program abbreviated ESPRESO (ExaScale PaRallel FETI SOlver). It is a highly efficient solver that contains FETI based algorithms. FETI, other than sounding like

The (short) story of a month at SoHPC

As you already know by reading the other SoHPCers posts, this adventure starts in Barcelona, more precisely on the beach, where we all took lessons on MPI, OpenMP, performance measurement tools, visualisation tools, etc. You might have also read all

Working at Jülich might seem an easy task for the inexperienced student. However, it is one of the most difficult challenges that one can face. It is impossible to keep track of how many students have tried, innocent as they
