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.”

Fujitsu Unveils Processor Details for Post-K Computer

The Fujitsu Journal has posted details on a recent Hot Chips presentation by Toshio Yoshida about the instruction set architecture (ISA) of the Post-K processor. “The Post-K processor employs the ARM ISA, developed by ARM Ltd., with enhancements for supercomputer use. Meanwhile, Fujitsu has been developing the microarchitecture of the processor. In Fujitsu’s presentation, we also explained that our development of mainframe processors and UNIX server SPARC processors will continue into the future. The reason that Fujitsu is able to continuously develop multiple processors is our shared microarchitecture approach to processor development.”

ARM Ramps up for HPC with SVE Scalable Vector Extensions

Over at the ARM Community Blog, Nigel Stephens writes that the company has introduced scalable vector extensions (SVE) their A64 instruction set to bolster high performance computing. Fujitsu is developing a new HPC processor conforming to ARMv8-A with SVE for the Post-K computer.

Call for Contributions: Hot Chips 2016

hotchipsThe Hot Chips 2016 conference has issues its Call for Proposals. The event takes place August 21-23 in Cupertino, California. “Presentations at HOT CHIPS are in the form of 30 minute talks using PowerPoint or PDF. Presentation slides will be published in the HOT CHIPS Proceedings. Participants are not required to submit written papers, but a select group will be invited to submit a paper for inclusion in a special issue of IEEE Micro.”

Video: AMD’s next Generation GPU and High Bandwidth Memory Architecture

“HBM is a new type of CPU/GPU memory (“RAM”) that vertically stacks memory chips, like floors in a skyscraper. In doing so, it shortens your information commute. Those towers connect to the CPU or GPU through an ultra-fast interconnect called the “interposer.” Several stacks of HBM are plugged into the interposer alongside a CPU or GPU, and that assembled module connects to a circuit board. Though these HBM stacks are not physically integrated with the CPU or GPU, they are so closely and quickly connected via the interposer that HBM’s characteristics are nearly indistinguishable from on-chip integrated RAM.”

Video: Altera’s Stratix 10 – 14nm FPGA Targeting 1GHz Performance

In this video from the 2015 Hot Chips Conference, Mike Hutton from Altera presents: Stratix 10 Altera’s 14nm FPGA Targeting 1GHz Performance. “Stratix 10 FPGAs and SoCs deliver breakthrough advantages in performance, power efficiency, density, and system integration: advantages that are unmatched in the industry. Featuring the revolutionary HyperFlex core fabric architecture and built on the Intel 14 nm Tri-Gate process, Stratix 10 devices deliver 2X core performance gains over previous-generation, high-performance FPGAs with up to 70% lower power.”

Video: Mars – A 64-Core ARMv8 Processor

In this video from the 2015 Hot Chips Conference, Charles Zhang from Phytium presents: Mars – A 64-Core ARMv8 Processor. Formed in China in 2012, Phytium is a unique technology provider of HPC servers, focusing mainly on high performance general microprocessor, accelerator chip, reference board design and various servers design from blade, cluster, standard stack to HPC Server. “Optimized for HPC, the Mars chip features eight panels, each with eight “Xiaomi” cores. The panels share an L2 cache of 32 MB, two Directory Control Units and a routing cell for the internal mesh.”
