The NASA space agency needs supercomputers that provide high power and processing capacity when performing complex simulations. However, the company does not scrap its machines or buy new ones to replace them, but rather upgrade your parts for years. Now the JAR announced who will be most powerful supercomputer to date, combining CPUs of Intel Yes amd.
NASA had upgraded a corporate supercomputer”Pleiades” since 2008, but the passing of the years was already noticeable and it needed more a change than an extension. For this he was born “aitken” in 2019, the supercomputer that would allow him to carry out his next Artemis missions and withstand his launch simulations. Now he has received a actualization which will make it the most powerful supercomputer in the history of NASA, and for this it will install AMD processors next to the Intel that I already had.
NASA supercomputer has over 308,000 AMD EPYC Rome (Zen 2) cores
Generally, universities and research centers build supercomputers monolithicwith a limited lifelike the exascale supercomputer Border. NASA, on the other hand, takes an approach modular when building your high-performing teams, allowing you to update them gradually and increase its power and capacity.
To understand it at a PC user’s level, imagine an OEM computer that, although cheap and offers enough power for its price, does not allow you to change its parts. Here, NASA would be the one to buy the computer for rooms and you can afford to change them in the future, increasing your team’s power. Obviously it goes much further, but it’s a simple comparison to understand the difference.
That said, NASA’s Aitken supercomputer is getting a 4-rack upgrade HPE Apollo which have processors AMD EPYC Roma architecture-based Zen 2. This leaves the system with a total 3200 knots (adding Intel and AMD) and adds more than 308,000 hearts of Rome, enormous additional computing power. Even before this upgrade, NASA’s Aitken supercomputer was already considered the number 58 from the list of the 500 most powerful systems in the world.
NASA computer previously had 46,080 Intel Cascade Lake cores
And it is that before adding this nonsense of AMD EPYC cores, the supercomputer already had 46,080 Intel cores under the architecture Cascades Lake. These were divided into 1,152 knots with 40 hearts per node distributed over 4 systems E-cell from HPE. This means that NASA has decided to combine Intel and AMD to create the most powerful supercomputer in its history.
“This huge improvement – an increase of 16% in the performance since its previous enlargement, and an increase 49% since last year, when the system ranked #72 on the June 2021 Top500 list. This translates to solving bigger problems with results faster for major NASA research projects in aeronautics, space exploration, earth sciences and astrophysics,” said Michael Moyerfrom the NASA Ames Research Center.
With this addition, the NASA supercomputer significantly increases its density, that is, the power available to it in its size is enormous. And we’re talking about a system that barely occupies 0.4 hectares (4000 m²) but has a performance of 13.12 PetaFLOP per second Yes 1.27 petabyte by heart.
