Our researcher Xavier Sáez gave a plenary talk on “HPC for solving multi-physics problems” at the 6th International Workshop on Numerical Modelling of High-Temperature Superconductors (HTS) in Costa de Caparica, Portugal.
Xavier focused his speech on the importance of multi-physics simulations to capture all relevant phenomena to model and simulate complex systems, and the key role of High-Performance Computing (HPC) due to the high computing resources required in those simulations.
The Summit supercomputer hosted at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) has been announced as the fastest supercomputer in the world, according to the TOP500 List.
The IBM Summit system reached a speed of 122.3 petaflops on the High-Performance Linpack benchmark test—the software used to evaluate and rank supercomputers on the TOP500 list. At its theoretical peak, Summit is capable of 200 petaflops (double precision), or 200 quadrillion calculations per second, about eight times more performance than its predecessor Titan.
Science and Research Ministers from Spain and Croatia, Pedro Duque and Blazenka Divjak, have signed a cooperation agreement pushing the candidature of Granada (Spain) for IFMIF-DONES facility.
Spain and Croatia presented initially independent candidatures but they joined their efforts in order to present a common European candidature. IFMIF-DONES aims to study the extreme conditions of fusion materials under energy production and particularly research on irradiation for DEMO operation. The estimated budget for the construction is between 400 and 600 million euros and the construction will take 10 years and it will be operating at least 20 years.
The European Union leads the clean-energy transition, aiming to reduce its greenhouse-gas emissions in 2050 by 80-95% from 1990 levels, which means almost decarbonising its energy system. The strategies for this transition were discussed today at the Energy Transition Conference in Barcelona organized jointly by the local UPC Barcelona-Tech University, Fusion for Energy, the Government of Catalonia and the municipalities of Barcelona and Sant Adrià de Besòs.
In the process of fusion energy production based hydrogen heavy isotopes deuterium and tritium as fuel, high-energy neutrons are released. These neutrons have many roles in a fusion reactor.
On one side, neutrons from the fusion reactions taking place in the fuel inside the reactor vacuum vessel generate the heat that, in a fusion plant, will initiate the electricity-producing process. Moreover, neutron interaction with lithium inside the machine will produce tritium.
The Divertor Tokamak Test (DTT) Facility will be built in Frascati, Rome, Italy, as has been announced by Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). It will be part of the International Center of Excellence for nuclear fusion research and will have a cost of 500 million euros.
This experimental machine will provide scientific and technological answers to some particularly complex problems of the fusion process (such as the management of very high temperatures) and stands as a “link” between ITER and DEMO international projects. Therefore DTT should operate integrating various aspects, with significant power loads, flexible divertors, plasma edge and bulk conditions approaching as much as possible those planned for DEMO, at least in terms of dimensionless parameters.
