Cerebras Wafer Scale Engine packs 1.2 trillion transistors

Cerebras, a start-up based in Los Altos, California, unveiled its Wafer Scale Engine - a record-setting AI processor boasting a die size of 46,225 square millimeters and containing more than 1.2 trillion transistors. The chip is 56X larger than the largest graphics processing unit and contains 3,000X more on-chip memory.

Key specs

  • 400,000 Sparse Linear Algebra (SLA) cores
  • 18GB on-chip SRAM, all accessible within a single clock cycle, and provides 9 PB/s memory bandwidth. 
  • 100 Pb/s interconnect bandwidth in a 2D mesh
  • Manufactured by TSMC on its 16nm process technology

The SLAC cores are flexible, programmable, and optimized for the sparse linear algebra, which underpins neural network computation. The cores are linked together with a fine-grained, all-hardware, on-chip mesh-connected communication network called Swarm.

“Designed from the ground up for AI work, the Cerebras WSE contains fundamental innovations that advance the state-of-the-art by solving decades-old technical challenges that limited chip size—such as cross-reticle connectivity, yield, power delivery, and packaging,” said Andrew Feldman, founder and CEO of Cerebras Systems. “Every architectural decision was made to optimize performance for AI work. The result is that the Cerebras WSE delivers, depending on workload, hundreds or thousands of times the performance of existing solutions at a tiny fraction of the power draw and space.”

The Cerebras product unveiling occurred at this week's Hot Chips Conference at Stanford University.

ADTRAN intros PoE Gigabit switches

ADTRAN announced its SDX 8110 series of Power over Ethernet (PoE) Gigabit switches featuring improved statistics reporting and a high level of traffic control for managing Service Level Agreements (SLAs) into the Local Area Network (LAN).

This increased flexibility enables service providers to simplify LAN management while supporting the increased penetration of IP phones, Wi-Fi access points and IoT devices within the enterprise.

The new PoE switches are available in 8, 24 and 48 port configurations and offer non-blocking Layer 2 and Layer 3 switching capacity up to 90 Gbps. The switches deliver 802.3at (POE+), 802.3af (PoE) and Legacy PoE support.

ADTRAN said that, in addition to the improved PoE budget, the SDX 8110 series offers service providers and customers increased control over traffic allowing them to extend SLAs into the LAN utilizing improved QoS capabilities. These Gigabit Ethernet switches add per-port and per-queue traffic shaping capabilities along with support for per-port and per-queue policing. Traffic matching capabilities have also been expanded to include QoS control lists that are used to match Ethernet frames, including both outer and inner tag parameters, and then manipulate various QoS, VLAN and policy settings in the IP packet or Ethernet frame.

“Improved traffic and PoE statistics give managed service providers visibility deep into the customer network to more easily monitor and diagnose problems,” ADTRAN Enterprise Product Line Manager Brian Lenahan said. “Expansion of ADTRAN’s SMB/Enterprise switch portfolio will continue with additional products planned for release over the next nine months.”

Keysight joins 6G Flagship Program

Keysight Technologies has joined the multi-party 6G Flagship Program, an initiative supported by the Academy of Finland and led by the University of Oulu, Finland.

The parties envision that next generation beyond 5G  will leverage spectrum above millimeter waves called terahertz waves, from 300 GHz to 3 THz, enabling data rates of up to one terabit per second and ultra-low latencies.

Keysight said its technical expertise and solutions across these frequency bands, as well as in high-speed digital technologies, cybersecurity, device characterization, and network test, will accelerate research in all four strategic areas of the program: wireless connectivity, distributed intelligent wireless computing, device and circuit technologies, and vertical applications and services.

“We’re excited to join the 6G Flagship Program as one of its founding members to begin groundbreaking 6G research,” said Satish Dhanasekaran, senior vice president of Keysight and president of Keysight’s Communications Solutions Group. “The program signals the start of a new era of wireless technology that will push the boundaries of high-speed and high-bandwidth applications. As the only test and measurement provider invited to take part of the program, Keysight is showcasing the unique role we play in solving design challenges ahead of a technology wave.”

“We’re excited to continue our close collaboration with Keysight to establish the world’s first 6G multi-disciplinary research initiative with broad support in both industry and academia,” said Matti Latva-aho Academy Professor, Director of the 6G Flagship Program at the Centre for Wireless Communications (CWC), University of Oulu.

First subsea fiber cable to be landed on St Helena island

The first fiber optic cable is expected to be landed on St. Helena, an island in the South Atlantic ocean that is a British Overseas Territory.

The fiber connection will be a spur from the main trunk of the Equiano cable, a new private subsea cable backed by Google that will connect Africa with Europe. The spur will be 1,140km long.

St. Helena is located 4,000 kilometres (2,500 mi) east of Rio de Janeiro and 1,950 kilometres (1,210 mi) west of the nearest point in Africa (the mouth of the Cunene River on the border between Namibia and Angola). The island has a population of 4,500.

Google announces Equiano cable from Portugal to South Africa

Google unveiled plans for new private subsea cable connecting Lisbon, Portugal and Cape Town, South Africa with branching units along the west coast of Africa.

The Equiano subsea cable, which is named for Olaudah Equiano, a Nigerian-born writer and abolitionist who was enslaved as a boy, will include a branching unit to Nigeria.

Google plans to use state-of-the-art space-division multiplexing (SDM) technology to achieve approximately 20 times more network capacity than the last cable built to serve this region.

The cable will be the first to incorporate optical switching at the fiber-pair level, rather than the traditional approach of wavelength-level switching. Google says this design will greatly simplify the allocation of cable capacity.

Equiano is fully funded by Google. Alcatel Submarine Networks was awarded a contract in Q4 2018. The first phase of the project, connecting South Africa with Portugal, is expected to be completed in 2021.

ADTRAN announces cloud-based CAF test for rural carriers

ADTRAN announced its fully-managed, cloud-based performance test solution for network operators that utilize the Connect America Fund (CAF) program and who will be required to submit testing results as part of their annual compliance in the first quarter of 2020.

To help ensure that the funds allocated are used for broadband service delivery in rural areas, the FCC has adopted Performance Monitoring and Measurement requirements to ensure greater accountability for recipients of Connect America Fund (CAF) high-cost universal service support, including price cap carriers, rate-of-return carriers, rural broadband experiment (RBE) support recipients, Alaska Plan carriers, and CAF Phase II auction winners.

The new service is an expansion of the ADTRAN CAF performance testing solution announced earlier this year. Since February, more than 30 CAF recipients have chosen ADTRAN’s network performance testing solution to comply with FCC reporting requirements.

ADTRAN said its managed testing solution takes care of each aspect of FCC compliance from initiating the test to collecting data to report creation and submission to the FCC in the format needed. It removes the administration burden related to CAF test compliance and utilizes the ADTRAN Speed Test Server Network as a cloud-based, managed service. The solution includes the SmartRG Device Manager Software to serve as the test controller and the SmartRG Gateways as the test clients and is available across the entire SmartRG portfolio of gateways.

“We developed this one-stop, fully-managed subscription service to give our customers peace-of-mind by offering a turnkey option that off-loads the entire testing process, so they can focus on what they do best—providing a superior subscriber experience,” ADTRAN Services Portfolio Manager Derek Foster said. “We know there is still some uncertainty with the FCC, which causes concern for our customers and that’s why we developed a simple and affordable compliance service.”
