Czech Hydrometeorological Institute puts NEC supercomputer into operation

Czech Hydrometeorological Institute (CHMI) researchers will soon be able to make use of a supercomputing system for high- resolution climate modelling. Used for climate research, it will help

predict the frequency and intensity of drought periods, and the change of extremity of weather phenomena such as flash floods and strong winds. The goal is to help prepare adaptation

measures, mitigating the impacts of changing climate. It also acts as a development system for the adaptation and optimisation of certain meteorological codes and climate applications that benefit from the vectorisation on SX-Aurora TSUBASA.

Dr Radmila Brozkova, head of CHMI’s numerical weather prediction department, said: ‘We are very happy to bring NEC SX- Aurora Tsubasa into operation. For us, NEC’s vector technology that SX-Aurora Tsubasa provides represents a highly attractive

alternative to competing HPC technologies, especially since we do not need to rewrite the majority of our productive codes. Another great advantage is the excellent ratio between the applicative performance gain factor and power consumption.’ The SX-Aurora Tsubasa supercomputer was delivered by NEC Deutschland in September and operational readiness was declared in December. At the heart of the system are 48 vector

Ferrari proves HUD concept can enhance racing safety MODELLING AND SIMULATION

A collaboration between Ansys and Ferrari has driven innovation in heads-up displays (HUD) for use in elite racing. The Ferrari Competizioni GT team employed Ansys’ engineering simulation technology to develop and test HUD for their Ferrari 488 GTE racing car. Drivers still receive

information on the race – such as car positions, any obstacles ahead, and crashes – via radio messages from their teams in the control centre. This can be complicated by issues of sending and receiving radio signals in crowded radio airspace. Ferrari sought to speed up

the relay of information, to project important data on the windshield, so the driver can view

information while looking straight ahead, without the need to take their eyes off the road. Mauro Barbieri, Ferrari’s GT

endurance racing performance enginee, said: ‘Communication among engineers, drivers and the pit crew is critical in a race, so we want to explore the most efficient means of giving the driver all the information they need to win. HUD are promising, not only for speed of communication but for added safety. Of course, to be safe the information must be clearly visible, without obstructing the course.’ Ferrari and Ansys engineers

used Ansys VRXperience software to virtually test the critical parameters of such a system. The HUD needed to be | @scwmagazine

blocking his view while driving at 200mph. Engineers used VRXperience

readable at all times, whether the sun is on the horizon and shining on the windshield, or when racing carries on into the night. The amount of data displayed and its location on the windshield is an important variable. Too much information overloads the driver, whose attention must focus on the track and the surrounding race cars. Data projected onto the windshield needed to be in positions that the driver can see easily without

to create a human-machine interface (HMI) for Ferrari drivers to evaluate the experience of driving with an HUD. ‘We have been considering adopting an HUD system for race cars for a long time,’ says Barbieri. ‘We were concerned about the time and effort it would take to design and test such a system. Collaborating with Ansys engineers and using SPEOS and VRXperience minimised the time it took to prove the concept of using HUD in race cars. Now we plan to continue using Ansys simulations as we further develop a working model for use on the track.’

hosts containing 384 vector engine cards, type VE 20B, in a directly liquid-cooled (DLC) environment. This is combined with a fully non-blocking high-speed interconnect based on Mellanox HDR InfiniBand network technology, and 18TB of HBM2 high-speed memory, and 24TB of DDR4 main memory. In addition, the system uses HPC parallel storage solution on the basis of the NEC LxFS-z storage appliance, with a usable capacity of more than 2 Petabyte deployed. Yuichi Kojima, managing director of NEC Deutschland and vice president HPC, said: ‘It is an honour for us that CHMI has selected NEC for the delivery of our latest HPC solution, which clearly guides the way into the future of climate modelling and weather forecasting. CHMI is a very important customer for us, and we are happy to provide our strongest support, not only for smooth operations but also by performance that optimises the climate applications in use.’
