Tech Update: Ethernet vs Infiniband for GPU clusters

Wondering whether to use Infiniband or Ethernet for building large-scale clustered GPU environments?

https://youtu.be/I2NKlVG3Ai0

Ram Velaga, SVP & GM, Switching and Routing from Broadcom explains: * Why Ethernet is the best technology for your needs, whether you're building a thousand GPU cluster or something larger. It's proven over multiple decades to meet new requirements as they arise. * How Ethernet has evolved to meet the requirements for clustered GPUs, including low latencies, controlling tail latency, and building large topologies without a lot of idle time on the GPUs. * The advantages of Ethernet, including its ubiquity, the scale of its market, the rapid innovation it drives, and the economies of scale it offers.

Samsung and MediaTek hit 363 Mbps uplink with 5G 3Tx antennas

Samsung Electronics and MediaTek achieved a peak throughput rate of 363 Mbps with  5G Standalone Uplink (UL) 2CC Carrier Aggregation (CA) with C-Band UL MIMO.

The test used used three transmit (3Tx) antennas to hit and uplink speed that is near theoretical peak.

The test was conducted in Samsung’s lab, based in Suwon, Korea. Samsung provided its 5G network solutions, including its C-Band Massive MIMO radios, virtualized Distributed Unit (vDU) and core. The MediaTek test device featuring its new M80-based CPE chipset began with one uplink channel apiece at 1,900MHz and 3.7GHz, but added an extra uplink flow using MIMO on 3.7GHz.

 “We are excited to have successfully achieved this industry breakthrough with MediaTek, bringing greater efficiency and performance to consumer devices,” said Dongwoo Lee, Head of Technology Solution Group, Networks Business at Samsung Electronics. “Faster uplink speeds bring new possibilities and have the potential to transform user experiences. This milestone further demonstrates our commitment to improving our customers’ networks using the most advanced technology available.”

 “Enhancing uplink performance using groundbreaking tri-antenna and 5G UL infrastructure technologies will ensure next-generation 5G experiences continue to impress users globally,” said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek. “Our collaboration with Samsung has proved our combined technical capabilities to overcome previous limits, enhancing network performance and efficiency, opening up new possibilities for service providers and consumers to enjoy faster and more reliable 5G data connectivity.”

Australia’s Titan Telecoms deploys Adtran for OLS

Titan Telecoms, an Australian provider offering dark fibre and wavelength services, has deployed Adtran’s FSP 3000 open line system (OLS) with flexgrid ROADMs and its FSP 3000 TeraFlex open terminal to create a high-capacity, ultra-flexible optical backbone network. 

The infrastructure supports speeds up to 800Gbit/s across the backbone, with customer-facing interfaces up to 400Gbit/s. 

Titan Telecoms is also using Adtran Ensemble software for network and service management, as well as the Adtran ALM proactive fiber monitoring solution.

“Our new network is great news for Australian businesses and service providers. It empowers us to expand quickly into new areas and reach more locations than ever before. With Adtran’s technology supporting rapid service rollout, we can help our customers stay ahead of the curve in today’s fast-changing digital landscape,” said Matt McDonough, CEO of Titan Telecoms. 

“We’re helping Titan Telecoms execute its ambitious plans to reach more areas and provide its customers with even more value. The new infrastructure significantly boosts capacity and guarantees maximum data throughput over every link,”  commented Erik Lindberg, GM of APAC sales at Adtran.

Sivers Photonics lands DFB laser array order from Ayar Labs

Sivers Photonics received a new US$1 million order from Ayar Labs for the development of next-generation DFB laser arrays.

The order will be delivered across 2023 and 2024 and includes agreed commercial terms for volume pricing in anticipation of future manufacturing by Sivers at larger volumes.

Sivers Photonics said its DFB laser arrays provide the high-quality light source for Ayar Labs’ SuperNova remote optical source product as they scale to volume production across a broad range of applications including AI/ML interconnects, disaggregated data centers, 6G networks, phased array sensor systems and more.

“We are excited to continue our strong relationship with Ayar Labs after our successful joint demos at both ECOC 2022 and OFC 2023. Utilising our proven technology, Ayar Labs can confidently deliver to their customers at scale, all whilst leveraging the continued growth of the CW-WDM MSA ecosystem for high bandwidth and channel count laser solutions.” said Dr Andrew McKee, Interim Managing Director, and CTO at Sivers Photonics.

“Ayar Labs is revolutionizing the way CPUs and GPUs will communicate within next generation HPC and AI/ML architectures. We are more than excited to be part of this journey with Ayar Labs and all its very prominent customers and partners. By enabling the switch to optical interconnect technology vs traditional electrical links, Ayar’s solution, leveraging Sivers technology, will provide a dramatic step change in the required bandwidth, power and latency improvements necessary for these complex systems to scale and meet the exploding demand for AI/ML clusters. With the massive growth of generative AI, , we believe this is just the beginning and are excited to support our customers in enabling the AI revolution that is changing the world.” said Anders Storm, Group CEO, Sivers Semiconductors.
