Microsoft deploys NVIDIA's H100 Tensor Core GPUs + Quantum-2 InfiniBand

Microsoft announced new massively scalable virtual machines that integrate the latest NVIDIA H100 Tensor Core GPUs and NVIDIA Quantum-2 InfiniBand networking. Azure’s new ND H100 v5 virtual machine for AI developers can scale across thousands of GPUs.

The ND H100 v5 VMservice is supported by:

  • 8x NVIDIA H100 Tensor Core GPUs interconnected via next gen NVSwitch and NVLink 4.0
  • 400 Gb/s NVIDIA Quantum-2 CX7 InfiniBand per GPU with 3.2Tb/s per VM in a non-blocking fat-tree network
  • NVSwitch and NVLink 4.0 with 3.6TB/s bisectional bandwidth between 8 local GPUs within each VM
  • 4th Gen Intel Xeon Scalable processors
  • PCIE Gen5 host to GPU interconnect with 64GB/s bandwidth per GPU
  • 16 Channels of 4800MHz DDR5 DIMMs

“Co-designing supercomputers with Azure has been crucial for scaling our demanding AI training needs, making our research and alignment work on systems like ChatGPT possible.”—Greg Brockman, President and Co-Founder of OpenAI. 

In a blog post, Microsoft's John Roach disclosed that since 2019, Microsoft and OpenAI have been working working in close collaboration to build supercomputing resources for training increasingly powerful AI models. The Azure infrastructure used included thousands of NVIDIA AI-optimized GPUs linked together in a high-throughput, low-latency network based on NVIDIA Quantum InfiniBand.

Coherent shows CPO 800G multimode optical engine

Coherent demonstrated a co-packaged (CPO) 800G multimode optical engine for use in cost-, power-, and latency-sensitive applications such as artificial intelligence and machine learning computer clusters. 

The module that features 16 channels of 50G NRZ transmitters and receivers in a 15 mm x 15 mm x 4 mm multimode CPO 800G VCSEL-based engine. 

The entire analog front end, including the driver, VCSEL, photodiode, and transimpedance amplifier, consumes less than 4 pJ/bit. 

Each VCSEL is paired with another unpowered device to enable 100% cold sparing for extremely high reliability.

Prototypes of this multimode CPO engine, which are jointly developed with IBM under the sponsorship of ARPA-E, are available for immediate evaluation.

Rivada to leverage Aalyria's Spacetime orchestration

Rivada Space Networks (RSN) will use Aalyria’s Spacetime platform to orchestrate the network for its planned LEO constellation.

Aalyria, which is based in Livermore, California, is a spin-out from Google. Aalyria's Spacetime software was used internally at Google and Alphabet for nearly a decade, and most recently powered the communications network for Project Loon’s various deployments in Peru, Puerto Rico, and Kenya. The technology already has millions of flight hours orchestrating and managing airborne communications systems around the world. Spacetime is also being used by the Defense Innovation Unit (DIU) to help develop secure internet connectivity throughout the space domain for both private and public sector customers.

Rivada’s constellation will consist of 600 satellites interconnected via laser links. The solution will offer integrated core and edge connectivity over a single, global private network in space. The first satellite launch is set for 2025, with global service starting in 2026.

Aalyria said its Spacetime solution will ensure robust and reliable means of communications between any two user terminals in the world through real-time analysis of millions of possible paths. Spacetime is an advanced software platform designed for orchestrating and managing networks of satellites, ground stations, aircraft, ships, urban meshes, and more. Spacetime optimizes and continually evolves the antenna link scheduling, network traffic routing, and spectrum resources -- responding in real time to changing network requirements. Spacetime operates networks across land, sea, air, and space, at any altitude or orbit type, supports all radio frequency bands and optical wavelengths, and is designed for interoperability with legacy, hybrid space, 5G NTN and FutureG network architectures.

“Rivada’s first-of-its-kind constellation is exactly the type of next generation connectivity system Spacetime was designed to advance,” said Chris Taylor, CEO of Aalyria. “We built Spacetime to dynamically route communications across anything that flies or moves, on Earth or in space, to expand connectivity to people, places, and things that were previously thought unconnectable. We’re excited to add Rivada to our roster of world-class partners and look forward to working with them in the coming years.”

Clemens Kaiser, Chief Program Officer at RSN commented: "With our manufacturing and launch services contracts in place we are now moving at full speed on defining the optimal systems solutions to deliver our ground-breaking constellation. We are delighted to be integrating Aalyria’s Spacetime solution and look forward to demonstrating that our fully meshed laser space network, regenerative payload and beam hopping solution can be very efficiently orchestrated to provide unparalleled service performance for our customers."

Keysight provides O-RAN testing for NTIA's 5G Challenge

The 2023 5G Challenge, which is led by the NTIA’s Institute for Telecommunication Sciences and hosted by CableLabs and its subsidiary, Kyrio, aims to accelerate the adoption of 5G open interfaces, interoperable subsystems, and modular, multi-vendor solutions by fostering a large, vibrant, and growing vendor community.

Keysight announced that its Open RAN Architect (KORA) solutions have been added to CableLabs’ 5G Lab to validate the interoperability of open radio access network (O-RAN) components during the event.

Specifically, Keysight’s KORA solutions will be used in the CableLabs 5G Lab to test edge-to-core O-RAN subcomponents, verifying interoperability and measuring performance. The Keysight P8800S UeSIM and P8822S RuSIM solutions will be used to emulate a baseline system with the P8850S CoreSIM O-RAN core emulator. This will enable the test lab to validate O-RAN radio units, distributed units, and central units, allowing contestants to optimize products and designs for the latest O-RAN specifications.

Keysight offers a comprehensive test portfolio that verifies end-to-end performance of 5G network elements and enables conformance, interoperability, performance, and security testing across the entire O-RAN lifecycle for Open Testing & Integration Centers (OTIC) such as Kyrio.

Jason Lauer, Vice President for Kyrio’s Engineering and Operations Group, said: “Expanding the capabilities of the 5G Lab and OTIC by adding the Keysight Wireless test solutions will provide 5G Challenge contestants and future OTIC testing vendors the opportunity to test end-to-end with multiple test platforms.”

Peng Cao, Vice President and General Manager for Keysight's Wireless Test Group, said: “We are delighted to support CableLabs’ 5G Lab with expanded testing capabilities with Keysight's complete interoperability and conformance solutions portfolio. Our equipment will allow 5G Challenge contestants to confirm that their subcomponents are interoperable with the subcomponents of other vendors.”
