Nikkei in Japan writes that the Post K supercomputer is facing 1-2 year delay for deployment as part of the Flagship2020 project. Originally targeted for completion in 2020, the ARM-based Post K supercomputer has a performance target of being 100 times faster than the original K computer within a power envelope that will only be 3-4 times that of its predecessor. Nikkei cites semiconductor development issues as the reason for the project delay.
Today the Green500 released their listing of the world’s most energy efficient supercomputers. “Japan’s research institution RIKEN once again captured the top spot with its Shoubu supercomputer. With rating of 6673.84 MFLOPS/Watt, Shoubu edged out another RIKEN system, Satsuki, the number 2 system that delivered 6195.22 MFLOPS/Watt. Both are “ZettaScaler”supercomputers, employing Intel Xeon processors and PEZY-SCnp manycore accelerators.
“We have been working on developing a number of tools that enable users to quantify power and performance in both software and hardware, and then design a more efficient system. We can also utilize the tools to predict the performance of a piece of software on a system that may not be available or does not yet exist – the aim is to take the guesswork away from novel system design.”
ARM processors will provide the computational muscle behind one of the most powerful supercomputers in the world, replacing the current K computer at the RIKEN Advanced Institute for Computational Science (AICS) in Japan. During the ISC conference, Fujitsu released details of the new system during a presentation with Fujitsu vice president Toshiyuki Shimizu. Shimizu stated that the “post K” system, which is set to go live in 2020, will have 100 times more application performance than the K supercomputer.
Now that ARM has been acquired, the big question is how much the Softbank investment firm will invest in bolstering their chips for HPC. Meanwhile, ARM continues to gain traction as evidenced by
today’s announcement that a paper on the ARM-based Mont-Blanc Project has been selected as a Best Paper Finalist for SC16. Entitled “The Mont-Blanc prototype: An Alternative Approach for HPC Systems,” the paper was written by Nikola Rajovic, a BSC researcher involved in the Mont-Blanc project since its beginnings.
The UK semiconductor company, ARM, may soon be acquired by Japan’s Softbank for £24.3 billion. The Cambridge-based firm is best known for designing microchips used in most smartphones, including Apple’s and Samsung’s. However, this year it was announced that the upgrade to the K computer, Japan’s flagship supercomputer housed at RIKEN would also use ARM-based processors.
The HPC industry is ever facing more and more challenges on various topics and especially a significant increase in cooling requirements. To meet those requirements, liquid cooling looks like the solution. But there is an alternative cooling solution that works without a pump and without water.
Today the ISC Group announced that the Green500 will be integrated with the TOP500 project with a single submission process. “This merge is of great significance to the high performance computing community,” said Erich Strohmaier, co-founder of TOP500. “Both projects will now be maintained under a common set of rules for data submission, which will simplify the process for submitters and provide a consistent set of data for the historical record.”
