The clusters were pulled from their previous locations and are being redeployed at new computing facilities, according to the press service. Yandex says none of the machines was damaged in the attacks by Ukrainian drones.
The supercomputers will continue to serve as infrastructure for the company's services and for training foundation language models, company representatives said.
Reuters, citing Yandex, reported the specifications of the clusters: Lyapunov, with a capacity of 20.03 petaflops, was launched in December 2020, while Chervonenkis at 29.42 petaflops and Galushkin at 20.64 petaflops followed in June 2021.
Two of the supercomputers were housed in a data center in Sasovo in the Ryazan Region and the third in Vladimir, Reuters reported. Yandex data centers in the Ryazan, Kaluga and Vladimir Regions were damaged in drone strikes on October 8, 9 and 11, causing disruptions to infrastructure and services.
A source close to the company told Forbes that the supercomputers do not depend on one another and can be kept in different places, since they are three independent nodes rather than a single supercluster. T-Invariant reported that Chervonenkis is the most powerful of the three, ranking 19th in the global top 500 supercomputers in 2021.
