CTC to accelerate simulation & visualisation through oneAPI

The CTC is expanding its Intel Graphics and Visualization Institute of Xellence (Intel GVI) to an Intel oneAPI Center of Excellence, which will help expand our understanding of the universe.

The oneAPI Center of Excellence will focus on advancing cosmological research, open-source code development, and in situ compute and visualisation, as well as teaching computational and visualisation coding techniques.

Over the past six years, CTC Director Professor Paul Shellard and the COSMOS computing team have collaborated with Intel on developing and optimising several codes with many simulations and visualization results for cosmology study. This includes areas such as the analysis of the Cosmic Microwave Background (CMB), simulations of Einstein’s General Relativity and the creation of gravitational waves during black hole or boson star collisions, and by cosmic string networks.

The COSMOS team, its work and computational and visualisation discoveries together with Intel were documented in the Discovery+ “UNIVERSE UNRAVELED” series currently available in select countries, including the UK.

A major goal of the Hawking CTC is to continue Professor Hawking’s vision of confronting our models of the Universe with the latest observations to reveal deep connections between quantum and galactic scales, while explaining such discoveries in ways understandable by everyone. Hawking recognised that this high precision data and our complex theories can only touch each other using powerful computers.

“We are honoured to be among the vanguard of institutions chosen to be an Intel oneAPI Center of Excellence, ensuring we build on our longstanding collaboration on in situ visualisation and code modernisation as we prepare to study the Universe at exascale,” said Shellard. “We’re committed to flexible platform-independent programming paradigms so that we can do more with fewer people, focusing on trying out new ideas and new algorithms for our cosmology workflows. The oneAPI development tools offer us a fast pathway on to the widest range of HPC architectures, especially the latest GPU accelerators, so we can respond to the flood of new cosmological data sooner.”

“Intel is pleased to extend the highly impactful work done by the Hawking CTC Intel Graphics and Visualization Institute by adding the centre to our growing family of Intel oneAPI Centers of Excellence,” said Jim Jeffers, senior principal engineer and senior director of Intel Advanced Rendering and Visualization. “As part of this program, the Hawking CTC can take full advantage of state-of-the-art software development tools and advanced CPUs and GPUs to break new ground in understanding our universe. This honours the legacy of Stephen Hawking and his passion, vision, and goal to answer the ultimate questions of our existence, our past and our future.”
