Cerebras packs 4 trillion transistor into CS-3 AI processor

Cerebras Systems introduced its Wafer Scale Engine 3 chip boasting 4 trillion transistors and 125 petaflops of peak AI performance through 900,000 AI optimized compute cores.

With a huge memory system of up to 1.2 petabytes, the CS-3 is designed to train next generation frontier models 10x larger than GPT-4 and Gemini. 24 trillion parameter models can be stored in a single logical memory space without partitioning or refactoring, dramatically simplifying training workflow and accelerating developer productivity.

Key Specs:

  • 4 trillion transistors
  • 900,000 AI cores
  • 125 petaflops of peak AI performance
  • 44GB on-chip SRAM
  • 5nm TSMC process
  • External memory: 1.5TB, 12TB, or 1.2PB
  • Trains AI models up to 24 trillion parameters
  • Cluster size of up to 2048 CS-3 systems

“When we started on this journey eight years ago, everyone said wafer-scale processors were a pipe dream. We could not be more proud to be introducing the third-generation of our groundbreaking water scale AI chip,” said Andrew Feldman, CEO and co-founder of Cerebras.“ WSE-3 is the fastest AI chip in the world, purpose-built for the latest cutting-edge AI work, from mixture of experts to 24 trillion parameter models. We are thrilled for bring WSE-3 and CS-3 to market to help solve today’s biggest AI challenges.” 


Arelion an Telxius boost connectivity in North and Latin America

Arelion and Telxius are collaborating to provide multi-terabit connectivity into Telxius’ landing stations in Boca Raton and Jacksonville, Florida. This fiber network expansion establishes Arelion Points-of-Presence (PoPs) at each Telxius landing station. 

For Telxius, it empowers customers with resilient Tier-1 optical transport and high-speed access to Arelion’s North American network. Together, Arelion and Telxius are making a significant investment in the Florida Peninsula to connect Latin American customers to North America through submarine and terrestrial systems.

Arelion’s PoPs enable resilient 400G Wavelengths services over open line systems supporting the latest coherent technology, seamlessly connecting Internet carriers and content providers to Arelion’s network in the United States. This network expansion complements Arelion’s existing presence at Telxius’ Virginia Beach landing station and further cements Arelion as a key terrestrial connectivity provider in North America.

Telxius’ Virginia Beach landing station is the landing point for three next-generation subsea systems connecting to Latin America and Europe: Brusa, Marea and Dunant. Telxius’ Boca Raton landing station is the terminal point for Telxius’ South America-1 (SAm-1) and upcoming Tikal submarine cable system, while Telxius’ Jacksonville landing station connects to the Pacific Caribbean Cable System (PCCS). Both landing stations provide diverse, high-capacity connectivity to the United States from Panama, South America and the Caribbean.

“Arelion’s new PoPs at Telxius’ landing stations along the Florida Peninsula will provide Latin American markets with high-capacity gateway access to the North American connectivity ecosystem,” said Edison De Leon, Regional Director Latam & Caribbean at Arelion. “Through this investment in the Florida Peninsula, Arelion continues our established partnership with Telxius to serve the technological needs of Internet carriers and content providers through complete, collaborative connectivity solutions.”


Integrating Infinera ZR/ZR+ Optical Modules with DriveNets Network Cloud

DriveNets and Infinera completed testing and certification of multiple Infinera ICE-X ZR/ZR+ modules that can be tunable, configurable, and manageable by DriveNets Network Cloud software. This will enable operators to reduce the number of network elements they need to manage and is made possible by advancements in ZR/ZR+ pluggables that support greater distances, eliminating most of the need for a separate optical network. 

The joint DriveNets/Infinera solution includes enhanced network configuration and management software capabilities and enables DriveNets solutions to seamlessly manage and benefit from the unique programmability and flexibility offered by Infinera’s ICE-X coherent pluggable solutions. 

It also enables network operators to leverage Infinera’s ICE-X pluggable solutions, such as 100G/200G Single Fiber bi-direction operation and 4x100G intelligent fan-out and offer new revenue-generating services such as 100G to 200G high-speed business services over single fiber PON infrastructures. 

The use of ZR/ZR+ on DriveNets Network Cloud delivers significant savings by collapsing layer-1 to layer-3 communications into a single platform. It also eliminates the need for standalone optical transponders, lowering the number of boxes in the solution, and reducing operational overhead, floor space, and power. In addition, the DriveNets NOS (DNOS) supports the Infinera modules in multiple modes of operations, including ZR, ZR+ and Open-XR.  

“Network operators are increasingly turning to open networking solutions that allow them to mix and match elements from multiple vendors, avoiding vendor lock,” said Nir Gasko, Vice President, Global Strategic Alliances for DriveNets. “Our integrated solution with Infinera enables operators to not only leverage the unique features of Infinera’s ICE-X ZR/ZR+ modules, but also benefit from the operational simplifications that the integration with DriveNets Network Cloud provides.” 

“DriveNets disrupted the market by introducing a disaggregated software-based networking solution that streamlined networking hardware over standard white boxes and redefined the economic model of the network,” said Russ Esmacher, Senior Vice President, Strategy, Marketing, and Corporate Development at Infinera. “Integrating our ICE-X ZR/ZR+ modules with DriveNets Network Cloud takes this disruption one step further, enabling our joint customers to further lower their OpEx and build more efficient, scalable, and robust networks.”

Celestial AI to showcase Photonic Fabric

At the upcoming #OFC24 in San Diego, Celestial AI will showcase its Photonic Fabric which provides breakthrough optical interconnect for memory and compute to meet the increasingly challenging requirements of AI workloads. 

Celestial AI says its Memory Fabric technology delivers over 25x greater bandwidth and memory capacity while reducing latency and power consumption by up to 10x compared to existing copper and optical interconnect alternatives. It offer tens of terabytes of optically scalable memory capacity, supporting current HBM3e and future HBM4 bandwidth and latency requirements. The Compute Fabric enables clusters of hundreds of GPUs or AI accelerators to be optically interconnected with industry-leading bandwidth at extremely low latency and energy consumption.

Celestial AI raises $100M for its Photonic Fabric Optical Interconnect

Celestial AI, a start-up developing an optical interconnect for disaggregated, exascale compute and memory clusters, raised $100 million in Series B funding.Celestial AI is working on Optical Compute Interconnect (OCI) to enable disaggregation of scalable data center memory and accelerated computing.  The company says its Photonic Fabric is unconstrained by package beachfront limitations and can deliver data to any location on the compute die,...

Equinix appoints Adaire Fox-Martin as CEO - formerly led Google Cloud

 Equinix named Adaire Fox-Martin as its next president and CEO, succeeding Charles Meyers who plans to transition to the role of Executive Chairman at the end of Q2 2024.
