Introducing LBDream and Literature-based discovery

In my last blog post, I described general MapReduce paradigm which allows us to create big data processing systems in a fairly simple way. In this blog post, I will describe more in detail what I’m doing in my project,

Bratislava: Chapter 2 out of 3

How to MPI So… In order to face the segmentation fault, Katerina performed changes in the allocations .. But not only in the makefiles, but into the input files too.. And that defeated the segmenation fault. But now she should

Assingnare Locus

Assignare Locus, the computer scientists equivalent of Expecto Patronum. This is the final blog in the trilogy, I am going to summarise the rest of the exciting experience I had in Slovenia along with a full description of the final

Greece. A place to be.

Random View in Greece. Get used to it, because it's that beautiful everywhere here.

Choosing Greece and BRFAA, Zoe Cournia lab, for my PRACE Summer of HPC destination was probably one of the best decisions of my life. To be honest, the project was pretty difficult sometimes and I had a few days of

Introduction to ParaView Catalyst

In my previous article you can find a brief introduction to the In Situ Visualization Technique which allows to explore simulation data during the run-time without involving storage resources of a supercomputer. Now it’s time to go a little bit further

Reaching the shore

It’s the 2nd of September now, and I am back in the Czech Republic again. I left Dublin 2 days ago, after finishing the work on my Summer of HPC project in ICHEC. So, let’s have a look back now

Better Jota that down, are you sure thats Ricet.

I feel like the second book in a trilogy is always the best, so fingers crossed this will be the best blog. After the first week in Ljubljana, my supervisor let me loose. This meant all the hard work and

A short tour of lattice QCD

As my first blog was completely non technical I am now contractually obliged by the powers that be to talk about some technical stuff of what I am actually doing. I decided I would have a go at explaining what lattice

Dare to visualize – Tornado effect

Sometimes in life we have to accept dares, challenges or we even have to make self commitments to achieve success. By the way, this is human nature, after reaching one milestone we look to the next, and according to me:

A Matryoshka linear solver

As I described in my previous posts, solving a linear system in a lattice QCD applications can be a very long process. We really want to optimize this linear solver, so we can find some answers about matter in our

Two applications for two techniques

Having already introduced you to the technique that will be used for my project in one of my previous posts let me share with you some more things about the application. The application will be used at outreach events and

Sophie’s World, Chapter 2: The project

In case you have cheched out this video, you might be wondering what this project is all about. In case you haven’t, I will wait for you 3:33 minutes to see it and return 🙂 Ok, now a little background

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 secret of Big Data programmers

In my last blog post, I described the problem of linkage prediction in large-scale graphs. I also mentioned that this is a big data processing problem. Today I will present you one of the biggest secrets of big data programmers:

Researching the center of Europe

After the amazing training week in Juelich Supercomputing Centre where we had a brief introduction to OpenMP, MPI, ParaView, CUDA and some Team Building, it was time to start with the real business. I got into a plane headed to the heart of

What’s in a virtual screening dataset?

In my previous blogpost, I explained the main objectives of my project. During these weeks, I have focused towards the data analysis side of HPC rather than working on optimizing a program that runs on a super computer. I have been working to

Shallow waters – the waves start to spread

I started the work on my project by exploring the provided simulation code. This is always a great adventure by its own, studying a code someone else has written before you. To those who never tried it, you definitely should.

Why is high performance computing so good for image analysis?

My Summer of HPC project  was officially titled “Development of  a sample application in PyCOMPSs”. As you can probably tell it’s a pretty vague title, and I was given a lot of freedom to come up with my own project,

This is happening!

According to a plan, last week I’ve finally started my first proper simulation. That means, that upcoming one will finally be more chilled (hopefully). I transferred the files from Maestro to Gromacs, solvated, added ions, minimized, equilibrated (see tutorial, but

Python, MPI, CFD and ARCHER – what is a bigger challenge?

Hi Guys! In this blog post, I would like to introduce you my project “Parallelising Scientific Python Applications” which I’m working on at EPCC under Dr. Neelofer Banglawala. Wait! Sit down, don’t worry and get a cup of excellent British tea.

From a Desolate Düren Platform to Spark in Slovakia

Its been one hell of a first couple of weeks here despite the worrying last leg of the trip to Juelich. Everything was smooth sailing until Düren train where the train to Juelich was leaving from an apparently non-existent platform

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
