I’ve had it with these Motherlovin’ Bugs on these Motherlovin’ Multipoles!

moth, c++, pointer errors, segfault

My project has reached a turning point! What I’ve now got is an Multipole2Local segment of the Fast Multipole Method written in C++ using HIP and thus it runs on both AMD and Nvidia GPUs. The next step is to

Bridging the gap between High Performance Computing and Big Data

In today’s blog post, I’ll talk about the successful (yaaaay!) progress of my project with a technical point of view. So if you are into Computer Science, I’m sure you will find this interesting! This post will be structured using

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

A first glance of Bratislava

Bratislava city picture

It’s been more than a week since the Summer of HPC program began, and these days have been quite interesting, getting to know members of the Computing Center of the Slovak Academy of Sciences and finding out more details about

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

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

Parallel boundary point method: Matlab has surrendered to C++!

After a little bit over a month of coding I can finally state it: Matlab has been knocked out! Both by the serial and parallel version of the C++ code actually. I am satisfied with that. Ever since I started

When FORTRAN met OpenCL – A Love Story? (of Integration)

Both of the projects Lukas and I are working on, here at NBI Copenhagen, are based on FORTRAN. Either Photon-Plasma simulations or CESM for climate modeling (as most climate modeling software around). Certainly, a vast majority of scientific code is
