Tianhe-2 is still the fastest supercomputer in the world
China's Tianhe-2 is still the fastest supercomputer in the world. This device can perform up to 33.9 petaflops, equivalent to 33 trillion billion calculations per second.
China's Tianhe-2 is still the fastest supercomputer in the world. This device can perform up to 33.9 petaflops, equivalent to 33 trillion billion calculations per second.
Tianhe-2 retains the top spot in the list of the world's 500 fastest supercomputers today. Chinese equipment ranked first, then to American and Japanese products, specifically the top 5 fastest supercomputers in the world:
1. Tianhe-2 (located in Guangzhou computer center in Guangzhou): Performed 33.86 petaflops.
2. Clay (located at Oak Ridge National Research Laboratory, USA): Implemented 17.6 petaflops.
3. Sequoia (located at Lawrence Livermore National Laboratory, USA): Implemented 17.2 petaflops.
4. K (manufactured by Fujitsu, located at RINKEN science institute, Japan): Implemented 10.5 petaflops.
5. Mira (produced by IBM, located at Argonne National Laboratory, USA): Implemented 8.5 petaflops.
Supercomputers are evaluated through the Linpack Benchmark system. This is a rating system using linear equations. However, some researchers believe that Linpack Benchmark is not objective and does not reflect the actual performance.
The head of the computer science department at IBM, Zurich (Switzerland) lab told the BBC: "We need a more realistic measurement that reflects the true capabilities of public-based supercomputers. what it does ".
