Paris, April 28, 2020
Two of the most highly effective supercomputers in France, Joliot-Curie, operated at the CEA’s supercomputing heart (TGCC), and Occigen, operated at CPU’s supercomputing heart (CINES), are giving urgent computing accessibility to substantial personal computer sources to European exploration groups involved in the struggle towards COVID-19. The purpose is to execute epidemiological studies of COVID-19 virus distribute, recognize its molecular framework and habits and massively display screen and examination probable upcoming molecules, to accelerate the lookup for an helpful vaccine and assistance the world-wide struggle towards the virus. Both equally supercomputers are centered on Atos’ BullSequana system, world-wide chief in electronic transformation.
Right after only a few months of GENCI’s COVID 19 speedy keep track of accessibility, GENCI, the French national substantial-efficiency computing company, announces that there are now much more than 20 scientifically diverse COVID19 assignments, running on its three national supercomputers between which are Joliot-Curie and Occigen (with each other with Jean Zay at IDRIS), with the committed help of assistance groups in these facilities.
Joliot-Curie at TGCC
Joliot-Curie, with its 22 petaflop/s, is the most highly effective supercomputer in France committed to tutorial and industrial open exploration. As component of PRACE (Partnership for Superior Computing in Europe), European scientists are relying on Joliot-Curie to operate these days a few COVID-19 substantial scale assignments in the context of the PRACE COVID-19 Rapid Observe simply call. One challenge simulates the functional proteins of the SARS-CoV-2 virus developed from hundreds of thousands of atoms to recognize the mechanisms of the virus infection in purchase to create therapeutics. The other challenge utilizes computational screening, a effectively-acknowledged method utilized in drug discovery, to establish and boost viral protein inhibitors, molecules which are able of blocking the SARS-Cov-2 protein. This challenge could help supporting the growth of a treatment method to gradual down the COVID-19 outbreak.
The final challenge brings together the analyze of the effect of antimalarial medicine on many human heart rate types getting into account a assortment of comorbidities that may well be existing in the contaminated population, and also utilizes computational fluid dynamics (CFD) to far better recognize the advanced hemodynamics affiliated with Nord-South Syndrome.
In addition to these PRACE COVID-19 Rapid Observe assignments, groups of scientists are carrying out preparatory simulations on precedence national allocations of computing potential on the Joliot-Curie supercomputer. For instance, scientists from the Grenoble Interdisciplinary Exploration Institute (IRIG) and the CEA’s Joliot Institute are doing the job on the lookup of inhibitors in COVID-19. The SPIKE protein lets the virus to penetrate the cell membrane. Thanks to the simulation of the digital framework of the protein and the affiliated inhibitor, it is feasible to provide precise information on the toughness of the inhibition but also structural information to establish the amino acids worried and their affiliated polarities. This first operate manufactured it feasible to validate the technique and thus to post a 15-million-hour challenge to PRACE to analyze the microscopic and thermodynamic things that may well or may well not favour the interaction among the primary SARS-CoV-2 protease and promising new inhibitors. The aim is to make an ab initio in silico resource to estimate accurately the interaction properties of proteins interacting with all types of ligand families.
Occigen at CINES
Among the the COVID-19 connected assignments on Occigen, scientists are running simulations to analyze the SARS-Cov-2 helicase enzymes in more detail, in purchase to far better recognize the genetic make-up of the virus. It is also remaining massively utilized – each day over and above 40,000 cores, about fifty percent of the total Occigen’s potential formed by 86,000 cores for three.five petaflop/s – with computational screening techniques, to practically examination much more than one.five billion molecules a thousand of which will be synthesized and examined in labs for their capacity to inhibit SARS-Cov-2. The scale of this virtual testing is unprecedented and is only manufactured feasible owing to the computing electricity of the supercomputer.
Stephane Requena, CTO of GENCI, stated: “We’re very pleased with the three national facilities to be in struggle towards COVID-19 and that our highly effective supercomputing and AI abilities are remaining utilized by scientists to add to these attempts. We hope that these computational results from the 20+ assignments now running on our techniques, will assistance scientists and scientists to recognize much more about the virus and eventually help create a treatment method to end this pandemic.”
Pierre Barnabé, Head of Community Sector & Protection and Head of Huge Knowledge & Cybersecurity, Atos, included: “We are honored to assistance those scientists and scientists in their operate to help struggle towards COVID-19. By applying the capacity of our BullSequana supercomputers, which operate hundreds of instances a lot quicker than regular desktops, we are enabling them to help you save beneficial time and helping obtain a heal to this pandemic.”
Christine Ménaché, Head of the CEA’s Very Big Computing Center (TGCC) and Boris Dintrans, Director of CINES jointly point out: “All the TGCC’s and CINES’s assistance groups have been mobilized in a potent spirit of solidarity to meet up with the expectations of all consumers and in individual these scientific assignments in connection with Covid19.”
Supercomputers have tens of hundreds of processors that operate with each other to execute substantial calculations, process and evaluate substantial amounts of info applying AI algorithms. GENCI’s entirely blended supercomputing techniques characterize these days much more than forty one petaflop/s of computing potential and 100 petabytes of significant info storage.
