Mladen Ivkovic’s Homepage

Hi there! Welcome to my homepage!

(Not sure how to pronounce my name?)

I’m a Career Development Fellow at Durham University in the Scientific Computing Group of the Department of Computer Science.

My background is in physics and computational astrophysics. My research revolves around numerical methods, numerical modelling, algorithm development, as well as performance analysis and optimisation of scientific high performance computing (HPC) software. I am especially interested in challenges arising in (astro)physical and cosmological simulations using particle methods, such as the required multi-scales and extreme spatial and temporal adaptivities, as well as in on-the-fly in situ analysis of such simulations. In a nutshell, I am researching how to design and write efficient and fast software to solve problems in numerical fluid dynamics which require the treatment of extreme differences in scales in both space and in time using supercomputers.

In terms of applications, so far my fields of research have spanned on-the-fly halo finding (group finding), on-the-fly construction of dark matter halo merger trees, computational fluid dynamics (using Finite Volume Methods, Finite Volume Particle Methods, and Smoothed Particle Hydrodynamics), and radiative transfer/radiation hydrodynamics in astrophysical codes that make use of MPI, OpenMP, and various task-parallel paradigms. I have worked on and with astrophysical codes like SWIFT and RAMSES and I have also worked on task-based SPH formalisms and the performance prediction and optimisation thereof with the Peano framework.
