National Supercomputing Center in Wuxi builds a yet another supercomputer that claims exascale performance. After the U.S. government imposed crippling sanctions against select Chinese high-tech and supercomputer companies through 2019 and 2020, firms like Huawei had to halt chip development; it is impossible to build competitive processors without access to leading-edge nodes. But Jiangnan Computing Lab, which develops Sunway processors, and National Supercomputing Center in Wuxi kept building new supercomputers and recently even submitted results of their latest machine for the Association for Computing Machinery's Gordon Bell prize.
The new Sunway supercomputer built by the National Supercomputing Center in Wuxi (an entity blacklisted in the U.S.) employs around feature approximately 19.2 million cores across 49,230 nodes, reports Supercomputing.org. To put the number into context, Frontier, the world's highest-performing supercomputer, uses 9472 nodes and consumes 21 MW of power. Meanwhile, the National Supercomputing Center in Wuxi does not disclose power consumption of its latest system.
Interestingly, the new supercomputer seems to be based on the already known 390-core Sunway processor that derive from the Sunway SW26010 CPUs and have been around since 2021. Therefore, the new system increased the number of processors, but not their architectural efficiency, so its power consumption is likely to be gargantuan. Meanwhile, actual performance of the machine is unknown, since scaling out has its limits even in the supercomputer world.
The National Supercomputing Center in Wuxi has not disclosed performance numbers of its new supercomputer, and it is hard to make any estimations about its performance at this point. The reason why we called it ‘exascale’ is because its predecessor, the Sunway Oceanlite from 2021, was estimated to offer compute performance of around 1 ExaFLOPS.
Meanwhile, engineers revealed the workload that it used the machine for. Apparently, the the group created a new code for large whirlpool simulations to address compressible currents in turbo machinery. They applied it to NASA’s grand challenge problem using an advanced unstructured solver for a high-pressure turbine sequence with 1.69 billion mesh components and 865 billion degrees of freedom (judged by the number of variables). Given how complex the simulation is, it is likely that the machine is indeed quite powerful. Meanwhile, there is no word whether the simulation was conducted with FP64 precision, or precision was sacrificed for the sake of performance.

Das Lufttaxi fliegt von selbst
Lufttaxis sind kleine Fluggeräte, die einen oder zwei Passagiere über eine kürzere Strecke in der Stadt oder von der Stadt zum Flughafen befördern sollen. Sie sollen autonom fliegen, das bedeutet, der Fluggast braucht keine Fluglizenz.

Die Idee ist, auf diese Weise die Staus auf den Straßen zu umgehen. "Das macht schon Sinn. Wenn ich von Zuffenhausen zum Stuttgarter Flughafen fahre, brauche ich mindestens eine halbe Stunde, wenn ich Glück habe. Mit dem Flieger wären es dreieinhalb Minuten", sagte Platen.
Porsche tritt mit seinem Lufttaxi gegen eine Reihe von Konkurrenten an, die bereits solche Fluggeräte gebaut haben, darunter die deutschen Unternehmen Volocopter und Lilium, der europäische Luftfahrtkonzern Airbus und das chinesische Unternehmen Ehang.
