Datacenter Efficiencies Through Innovative Cooling

Datacenters that are designed for High Performance Computing (HPC) applications are more difficult to design and construct than those that are designed for more basic enterprise applications. Organizations that are creating these datacenters need to be aware of, and design for systems that are expected to run at their maximum or near maximum performance for the lifecycle of the servers.

Parallella Tapes Out 1024-core Epiphany-V Chip

Over at the Parallella Blog, Andreas Olafsson from Adapteva writes that the company has reached an important milestone on its next-generation Epiphany-V chip. “Thanks to a generous grant from DARPA, we just taped out a 16nm chip with 1024 64-bit processor cores. To give a comparison, our 4.5B transistor chip is smaller than Apple’s latest A10 chip and has 256 times as many processors. The chip offers an 80x processor density advantage over high performance chips from Intel and Nvidia.”

Video: Sustainable High-Performance Computing through Data Science

Ozalp Babaoglu from the University of Bologna presented this Google Talk. “At exascale, failures and errors will be frequent, with many instances occurring daily. This fact places resilience squarely as another major roadblock to sustainability. In this talk, I will argue that large computer systems, including exascale HPC systems, will ultimately be operated based on predictive computational models obtained through data-science tools, and at that point, the intervention of humans will be limited to setting high-level goals and policies rather than performing “nuts-and-bolts” operations.”

ARM Releases CoreLink Interconnect

“The demands of cloud-based business models require service providers to pack more efficient computational capability into their infrastructure,” said Monika Biddulph, general manager, systems and software group, ARM. “Our new CoreLink system IP for SoCs, based on the ARMv8-A architecture, delivers the flexibility to seamlessly integrate heterogeneous computing and acceleration to achieve the best balance of compute density and workload optimization within fixed power and space constraints.”

Earlham Institute Tests Green HPC from Verne Global in Iceland

“As more organizations turn to high performance computing to process large data sets, demand is growing for scalable and secure data centre solutions. The source, availability and reliability of the power grid infrastructure is becoming a critical factor in a data centre site selection decision,” said Jeff Monroe, CEO at Verne Global. “Verne Global is able to deliver EI a forward-thinking path for growth with a solution that combines unparalleled costs savings with operational efficiencies to support their data-intensive research.”

Phytium from China Unveils 64-core ARM HPC Processor

This week at the Hot Chips conference, Phytium Technology from China unveiled a 64-core CPU and a related prototype computer server. “Phytium says the new CPU chip, with 64-bit arithmetic compatible with ARMv8 instructions, is able to perform 512 GFLOPS at base frequency of 2.0 GHz and on 100 watts of power dissipation.”

Post K Supercomputer Delayed in Japan

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.

Riken’s Shoubu Supercomputer Leads Green500 List

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.

Adept Project Explores HPC Energy Efficiency

“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 to Power New RIKEN Supercomputer

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.
