Group of the Week (V): MONO

As the regular follower of the Group of the Week series that you are, you have of course noticed that I have posted two groups within the same week. I meant to post the previous one on Beck even before Christmas but something annoying like work got in the way.

Anyway, here we go with a great discovery:
MONO, a post-rock/experimental rock group from Japan. When I saw the announcement of a concert in Zurich, I remembered that a few years back I read a review of their album For My Parents in the (german) music review page Abgehört. I also remember that I liked it at the time but probably did not listen to it very intensely. Now, I went back to listen to their music. They have a new double feature album out The Last Dawn and Rays Of Darkness, which received another outstanding review on Abgehört but I think you just need to listen to it yourself, which you can do (and afterwards buy) on Bandcamp. The Hymn to the Immortal Wind is maybe one of the greatest albums I’ve listened to (and the others aren’t really worse).

They played a great concert with a full orchestra supporting them in NY. Other concert videos are worthwhile too, and I am sure that the show in Zurich will be no worse. See you there 🙂

As usual you can listen to it on Spotify:

New Job from August 2014

I am starting a new position tomorrow — and will convert into a geophysicist (watch this for some background info). These are my new utensils:The geologist utensils

Ok, seriously:
I wish to thank the Alexander von Humboldt-Foundation for supporting me over the last two years.
Particularly, I wish to thank Prof. Christian Hafner and the Institute of Electromagnetic Fields at ETH Zurich. Prof. Hafner was as welcoming as anyone can possibly be. Experiencing how he still enjoys his research after more than 35 years made a strong impression on me. Thank you!

Starting from August I am with the Geophysical Fluid Dynamics group of Prof. Tackley at ETH. They give me the opportunity to join the GeoPC project, which deals with infrastructure development for hybrid parallel smoothers for multigrid preconditioners. GeoPC is part of the larger PASC (Platform for Advanced Scientific Computing) initiative. The abstract of the project proposal reads:

The GeoPC project is developing computational infrastructure to enable massively parallel, scalable smoothers and coarse grid solvers to be used within multigrid preconditioners. This infrastructure is intended to (i) facilitate the execution of high resolution, 3D geodynamic models of the planetary evolution; (ii) provide the Earth Science community (and others) with a suite of continually maintained and re-usable HPC components to build robust multi-level preconditioners (iii) position Swiss computational geosciences in the emerging exa-scale era.

GeoPC is a PASC co-design project involving the University of Lugano (USI), the Swiss Federal Institute of Technology (ETH), University of Chicago (UC), Vienna University of Technology (TU Wien), as well as other stakeholders.

Our developments will become part of PETSc, the Portable, Extensible Toolkit for
Scientific Computation. I am very much looking forward to contributing to a library as renowned as PETSc!

Short course on Discontinuous Galerkin Methods

This Wednesday (July 4, 2012) Jens Niegemann, Benedikt Oswald and me held a short course on Discontinuous Galerkin Methods as part of the 8th Workshop on Numerical Methods for Optical Nano Structures.

I covered the introduction (part I), Jens spoke about the DGM on tetrahedra and necessary extensions for performing simulations of realistic nano-structures including the implementation of dispersive media and Perfectly Matched Layers (PMLs). He also covered performance considerations and the implementation of the DGM on modern graphics processing units (GPUs) as well as improvements of the time integration (part II).

In part III, I discussed the DGM on irregular meshes (meshes containing hanging nodes) as well as adaptivity. The former is a prerequisite for performing unconstrained adaptive mesh refinement, specifically hp-adaptivity. All of the above is dealing with the DGM in time-domain.

In part IV, Benedikt moved on to frequency domain formulations and discussed the symmetric interior penalty DG method (SIP-DG).

The slides will soon be available on the workshop website. My own slides are also available here Part I and here Part III. Please note that the focus of the course is on explaining basic ideas rather than rigor.

Research Fellowship

The Alexander von Humboldt-Foundation granted me a Feodor Lynen-Research Fellowship starting from June 1st, 2012.

A Feodor Lynen Research Fellowship for postdoctoral researchers allows you to carry out a long-term research project (6 to 24 months) you have selected yourself in cooperation with an academic host you have selected yourself at a research institution abroad.
(Quoted from here)

In my case the host will be Prof. Hafner, chair of the IFH – Lab for Electromagnetic Fields and Microwave Electronics at ETH Zurich, Switzerland. I wish to express my thankfulness to both, the Alexander von Humboldt-Foundation and Prof. Hafner for providing me with this great opportunity!
