Mmh! Now THIS is a Tasty Kernel!

me, with an afro, eyeing a tasty cuda kernel

Like all entropy-generating processes, the Summer of HPC must come to an end. However, you won’t get rid of me that easily, since there’s still one more blog post left to be done! This time I’ll tell you more about

The Case of the Missing Device Function

It's me, browsing my Magic: the Gathering collection.

My project has been progressing quite well and a bit more of that in the next blog post. However, this time I present a more detailed description of the beginning of my project. The narrative may have been dramatized in

The HIPbit, or There and Back Again

Forschungszentrum Jülich is quite an interesting place to work at. You can think of it as a town in the middle of nowhere where over the half of the population are scientists or technicians. The research center even has its

Antti Mikkonen

Greetings from the far north! My name is Antti and I like all sorts of things mathematical. There’s just something very savoury about a well-structured, intuitive and dumbfounding mathematical proof. Basically, I like to look for problems and solve them.

Cude colors on a phine grid

Project reference: 1716 Simulations of Lattice Quantum Chromodynamics (the theory of quarks and gluons) are used to study properties of strongly interacting matter and can, e.g., be used to calculate properties of the quark-gluon plasma, a phase of matter that

Hip, hip, hooray! Get your 2-for-1 GPU deal now.

Project reference: 1717 Today’s multi-core, many-core and accelerator hardware provides a tremendous amount of floating point operations (FLOPs). However, CPU and GPU FLOPs cannot be harvested in the same manner. While the CPU is designed to minimize the latency of

Scotland for the summer, seriously?

  “It’s gonna be cold and rainining up there the whole time…” If I got a pound every time  I heard that in the last months, I could buy a kilt (which are not cheap by the way). While most

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

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

Exploring Germany

Now that I have settled into life in Jülich (and on a good day I can get to the office without getting lost), I decided it was time to explore the surrounding area.  There are many larger cities surrounding the

How to work at Jülich in a nutshell

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

Getting lost in Juelich

A Summer of HPC started with a week in Barcelona. This week comprised of intensive training sessions in high performance computing tools and techniques. This was a good opportunity for people like me with no previous high performance computing knowledge

Making Quarks phli further

Simulations of Lattice Quantum Chromodynamics (the theory of quarks and gluons) are used to study properties of strongly interacting matter and can, e.g., be used to calculate properties of the quark-gluon plasma, a phase of matter that existed a few milliseconds after the Big Bang (at temperatures larger than a trillion degrees Celsius). Such simulations take up a large fraction of the available supercomputing resources worldwide.

A Fast Multipole Toolbox for GPU cluster

Modern multi- and many-core hardware architectures provide a huge amount of floating point operations (FLOPs). To harvest these FLOPs efficiently a lot of parallelism in the examined algorithm needs to be uncovered and exploited. Performance boosts are well hidden in low-level hardware features of the CPUs or GPUs. The great diversity and short life cycle of todays HPC hardware does not allow for hand-written, well-optimized assembly kernels anymore. This begs the question if we can utilize the hidden performance from high-level languages with greater abstraction possibilities like C++.

Marco Borelli

My name is Marco Borelli, and I’m writing from Jülich, Germany. For my Summer of HPC project I was assigned to the supercomputing facility of Jülich Forschungszentrum, a beautiful research center located in the region of North Rhein-Westphalia. My project consists of an implementation of the Fast Multipole Method on (GP)GPUs.

David Hermosa Garcia

The past weeks at the Forschungszentrum in Juelich (Germany) have been awesome. I’ve been granted a bike to move around and I found myself enjoying the differences between my place in Spain and here. I suppose it’s the same as traveling anywhere else, but the weather, the forests and the German culture in general are a great change for me.

SoHPC Team Scores Last in Pub Quiz!

A mixed German-Austrian-Finnish-Turkish team scored last in Monday’s pub quiz at Reverie in Newington Road, Edinburgh, and earned nothing but laughter and disgust for the worst joke ever. We won’t tell it here, no chance. The evening started when our
