Picture of me

Ole Holm Nielsen, PhD

My position is Senior HPC Officer for supercomputing at the Department of Physics at the Technical University of Denmark.

My professional background is in theoretical solid state physics, primarily electronic structure, total energy and stress calculated within the Density Functional Theory.

In the summer of 2002 we built a 2.1 TeraFLOPS Linux cluster supercomputer NIFLHEIM out of 480 desktop PCs, which was one of the fastest computers in Europe at the time of installation. In 2017 NIFLHEIM (after several generations of hardware upgrades) has about 11000 CPU cores and 235 TeraFLOPS peak performance, and continues to provide an important infrastructure for the department's research.
