H4H

Project results

Key to the technological progress achieved were the extensive collaboration and workshops in which the partners engaged to develop and test the various technologies, customisation and optimisation options, and ultimately produce significant innovations to all the H4H technology components. Key results included:

• A new HPC architecture including new accelerators based on GPU and MIC technologies.
• A tailored development environment including optimisation tools and libraries supporting the new hardware architecture, allowing performance improvements (by an acceleration factor of 2 to several tens in application execution time).
• An advanced cooling design enabling a large reduction of the energy needed to operate the future Exascale HPC systems.

Exploitation

The H4H project made important contributions to the Bull Exascale Program, which aims to design and develop the next generation of supercomputers. H4H contributions were packaged within the Bull Super Computer Suites 4 & 5. In 2015, Bull launched Sequana - an open range of supercomputers that is ready to support future Exascale technologies. Bull benefited from these H4H developments as the new cooling technologies lead to new cooling improvements in the Sequana commercial offering, currently being sold as the Bull Sequana X, in which the X1210 blades integrate the latest Intel’s Xeon Phi technologies.

During H4H. RECOM achieved major performance improvements of its 3D combustion simulation software. Shortly after H4H, 50% of RECOM’s turnover from traditional contracts in the coal-based power generation sector disappeared due to an increasing share of renewable power generation in the European grid. This had to be compensated by expanding the applicability of the RECOM AIOLOS software to other industrial sectors, which required a huge effort in combustion model development and validation of its predictive quality in these new fields within a very short period. The performance improvements achieved in H4H have enabled RECOM to make this transition happen within less than two years.

H4H allowed Efield to drastically improve the performance of their electromagnetic solvers to successfully address the industry’s evolution towards higher operating frequencies, complex materials and increased density of ICT equipment. Efield and Scilab enterprises (open source software for numerical computation with HPC optimisations), both H4H SME partners, were acquired by a larger company ESI group.

Optimisation strategies developed in H4H were implemented by Dassault Aviation on proto-applications referring to highly computational parts from its industrial code. Thanks to the ITEA COLOC project, which was a follow-up of H4H, Dassault Aviation was able to improve the parallel efficiency of its in-house software to maintain its competitive edge in the aeronautics industry.

Based on H4H, CEA improved its CEA Computing Complex infrastructures in terms of computational power and energy efficiency. CEA-LIST, also signed a commercial contract with the “Gendarmerie Nationale” for its image-based stolen object retrieval. The contract is still ongoing in 2018 evolving to other types of recognition features.

Thanks to H4H, Jülich Supercomputing Centre got the opportunity to work in a Siemens-funded collaboration (2014-2015) together with the Corporate Technology Multicore Expert Center of Siemens AG on runtime analysis of parallel applications for industrial software development.
