High-performance computing challenge: How can engineers effectively leverage HPC technology?

High-performance computing challenge: How can engineers effectively leverage HPC technology? When developing or improving products, engineers face the challenge of analysing complex simulations to test their designs. High-performance computing (HPC) is used to solve major problems in engineering by performing demanding operations such as simulations relatively quickly. Also, by processing more precise operations, HPC can […]

Nek5000 in EXCELLERAT: towards Exascale

Nek5000 in EXCELLERAT: towards Exascale One of EXCELLERAT’s tasks is improving Nek5000’s Exascale readiness, particularly with respect to accelerators. As a starting point, we used an OpenACC version of the proxy-app Nekbone and focused on further optimising the small matrix-matrix kernels which constitutes most of the work in the full Nek5000. By tuning the OpenACC […]

New EXCELLERAT Service Portal is launched

New EXCELLERAT Service Portal is launched We are pleased to announce the launch of EXCELLERAT’s redesigned Service Portal. By presenting a wide variety of resources in an easily-accessible format, the Portal will play an essential role in EXCELLERAT’s mission to create a Centre of Excellence in Engineering. We have adopted a user-centric approach, and the […]

Dynamic Load balancing for Airplane simulations on Heterogeneous pre-Exascale architectures

Dynamic Load balancing for Airplane simulations on Heterogeneous pre-Exascale architectures We can affirm with quite a certainty that future Exascale systems will be heterogeneous, including accelerators such as GPUs. We can also expect higher variability on the performance of the various computing devices engaged in a simulation; due to the explosion of the parallelism, or […]

EPCC develops new modelling techniques for the chemical and oil and gas industry ​

EPCC develops new modelling techniques for the chemical and oil and gas industry Global equipment manufacturers in the chemical and oil and gas industry, such as Sulzer Chemtech, often rely on commercial Computational Fluid Dynamics (CFD) software tools for the design of their equipment. These commercial codes are currently unable to handle complex twophase flows […]
