Introduction to PDC

The PDC Center for High Performance Computing (which is usually known as PDC) is hosted at the KTH Royal Institute of Technology (or KTH) in Stockholm. PDC provides leading high performance computing (HPC) services that are used for academic and business research. Those services include supercomputing and data storage resources, software for simulation and modelling, plus assistance from a range of application and system experts. Application experts are researchers with expertise both in high performance computing and in another research field, for example, molecular dynamics or computational fluid dynamics.

Beskow, the largest academic supercomputer in the Nordic countries

PDC's main supercomputer system is called Beskow. It is a Cray XC40, based on Intel Haswell and Broadwell processors and Cray Aries interconnect technology. Beskow has a total of 11 cabinets  (placed in two rows) and the system has a theoretical peak performance of 2.43 petaflops, which far exceeds a typical personal computer (PC) or laptop. (See table below for some other comparisons between Beskow and a typical PC).

PDC is involved with various national and international projects and research centres that work to promote the use of high performance computing in research, and to improve the existing HPC infrastructures for research in Sweden and in Europe, as well as paving the way to making exascale computing a reality.
