High Performance Computing

The top 10 of the November 2024 list of supercomputers is very much a western affair, all coming from the US, Europe and Japan. But in fact, if China’s fastest supercomputers were listed, they would be third and fifth on the list. And the commercial sector is building machines that are even faster than the number one.

Every year, humanity uses some 40% more of the earth’s resources than the earth can sustainably supply in that year. Clearly, this cannot go on forever. Awareness of this is growing and major transitions are starting to take shape. As an expert in developing computational software, VORtech sees an important role for itself in developing the software for computing and simulation that is needed to make these transitions. We are happy to see this already reflected in our client portfolio.

If runtime is a problem for your application, then the use of a general-purpose graphics processing unit (GPGPU) can be a solution. GPGPUs can sometimes speed up computations by an order of magnitude. As an extra advantage they use far less power per computation. But exploiting their computational power is not always easy and only works for applications that meet specific requirements.

The launch of ChatGPT made the world aware that Machine Learning will fundamentally change the way we live and work. The field of computing and simulation will be no exception. But it’s not just ChatGPT: there are other innovations from machine learning that are bringing exciting changes for computing. In this blog, we’ll explore the potential of this new technology.

Model-order reduction is a powerful technique to speed up simulations. It can be used to solve performance issues in applications like design optimization, model-based predictive control, or digital twinning. In this blog, we’ll give a very basic introduction to these techniques and describe some experiments that were done at VORtech by two interns at VORtech, Floris Roodenburg and Abinash Mishra. They could speed up calculations by more than a factor of ten.

Burn injuries can have a radical impact on someone’s quality of life. A burn injury in the neck, for example, can cause a contraction that makes it impossible for someone to lift his or her head. Complications such as hypertrophic scars and contractions can occur as the result of burn injuries. In the first-place, hypertrophic scars cause aesthetic problems. In the case of hypertrophy, the scar is thicker and more elevated than normal. The second class of complications, an excessive contraction, often causes reduced mobility of the joint of the patient.

Wat is er de afgelopen 10 jaar gebeurd op het gebied van de hardware voor het grotere rekenwerk, oftewel de High Performance Computing (HPC)? En wat staat ons de komende jaren te wachten? We gingen in gesprek met twee systeembouwers en we kregen van hen een vogelvlucht perspectief van de ontwikkelingen in HPC-platformen.

Is High Performance Computing converging or diverging? Will there be generic HPCexperts or does each platform require its own expert?

An HPC software tool Par@graph has been developed to analyze the very large climate networks by the LINC project, funded by EC’s Marie-Curie ITN program.
