UCL Acquires 181 Teraflop Computing Resource

Mar 06, 2016

Researchers from across University College London are now benefitting from a brand new High Performance Computing (HPC) system, 'GRACE', in honour of pioneering computer scientist Grace Hopper.

Designed and integrated by HPC big data and analytics integrator OCF utilising Lenovo and DDN technology, the new central HPC resource will complement specific UCL Departments’ specialist HPC services and will run alongside its existing HPC machines ('Legion' and 'Emerald').

That means UCL boffins in Neuroscience, Engineering, Environmental Sciences and Biological Sciences can join those from maths and physical sciences to take advantage of the new system, which  s already contributing to research into environmental air quality and nanoscale chemistry for electronics through to chemical binding to develop better drugs and the development of algorithms for managing genomes.

“In our research, we employ high performance computing facilities to solve the complicated quantum mechanics equations that govern molecular crystals, which play a vital role in understanding the physics and chemistry of other planets," said Dr. Sam Azadi, Research Associate, Department of Physics and Astronomy, UCL.

“The availability of GRACE and its thousands of cores is opening up new possibilities for our research - understanding molecular crystals’ behaviour under exotic conditions is crucial for modelling the structure, dynamic and evolution of the large planets.”

“Grace is the result of continued focus on support for world-class computational science and research at UCL,” added Clare Gryce, Director, Research IT services at UCL.

“The system replaces the Iridis3 service previously provided though our founding partnership in the Science and Engineering South consortium. At 181 Teraflops, Grace provides a step change in computational capability to researchers at the University.”

Maths And Physics Dominate

Housed at VIRTUS, the UK’s first shared data centre for research and education in Slough, Grace will be UCL’s flagship HPC service and is free at the point of use for researchers across the University. Usage tends to be dominated by the maths and physical sciences space,  in part due to application suitability for parallelisation, says the GRACE team.

But although only going live in December 2015, the new system has already seen more than 50 users so far, with more expected in the coming months.

The supercomputer array is based on Lenovo NeXtScale servers connected to DDN SFA7700, providing 500TBs of usable data between home and scratch, 10% of which is already in use.

The HPC machine will provide core services across UCL faculties, and operates the same software environment as the Legion system, enabling researchers to migrate between systems easily.

“Using a standardised software environment across GRACE and Legion means researchers migrating their work between machines can do so easily, without the need to re-engineer applications,” commented Dr. Owain Kenway, Research Computing Analyst.

Owain added that both systems will continue to be updated and upgraded in a 'leapfrog' process each year.

“OCF has successful partnerships with world leading vendors so were effective and responsive in bringing together the different partners to address any problems, and its team did a great job as broker, mediator and integrator," he added.
