NVIDIA Announces DGX H100 System

NVIDIA today announced the fourth-generation NVIDIA® DGX™ system, the world's first AI platform built with the new NVIDIA H100 Tensor Core GPU.

The DGX H100 system provides the scale needed to meet the massive computational demands of large language models, recommender systems, healthcare research and climate science. Each system contains eight NVIDIA H100 GPUs connected as one via NVIDIA NVLink®, each DGX H100 delivering 32 petaflops of AI performance at the new FP8 precision – 6x more than the previous generation.

The DGX H100 system is the building block of the next-generation NVIDIA DGX POD ™ and NVIDIA DGX SuperPOD ™ AI infrastructure platforms. The latest DGX SuperPOD architecture uses the new NVIDIA NVLink switching system to connect up to 32 nodes for a total of 256 H100 GPUs.

Rohde & Schwarz offers O-RAN radio unit solution

Rohde & Schwarz and VIAVI Solutions Inc. today announced that they have partnered to provide an integrated solution for compliance testing of O-RAN radio units (O-RUs). The two companies are leaders in wireless communications testing and actively participate in the specification development of the O-RAN Alliance, combining their respective industry-leading capabilities. At the heart of the joint solution is the O-RU Test Manager, which provides a seamless user experience. The solution will be demonstrated at MWC Barcelona 2022 from February 28th to March 3rd at Rohde & Schwarz booth 5A80.

O-RAN is making radio access networks more open, decentralized and flexible. An open network architecture can foster innovation, meet individual needs, and improve network efficiency. As such, O-RAN is experiencing rapid progress and growth in the technology ecosystem. The O-RAN Alliance includes more than 300 service providers, vendors and research institutes, and the number of participants at O-RAN Global PlugFest 2021 has doubled from the previous year.

Network disaggregation in O-RAN brings new challenges in terms of interoperability between network equipment from different vendors. Fronthaul conformance testing, defined by the O-RAN Alliance, ensures that evolving O-RUs are interoperable with O-RAN Distributed Units (O-DUs).

GE Successfully Completes Phase 1 Testing of Second XA100 Adaptive Cycle Engine

GE has completed Phase 1 testing of its second XA100 adaptive cycle engine as part of the U.S. Air Force's Adaptive Engine Transition Program (AETP). The first phase of testing, conducted at GE's Altitude Test Facility in Avondale, Ohio, allows GE to continue to collect high-quality performance data to validate the engine's conversion propulsion capabilities. Phase 2 testing will begin in the first quarter of 2022 at the Air Force's Advanced Test Facility at the Arnold Engineering Development Center (AEDC).

"Phase 1 testing allowed us to further characterize engine operation and allowed us to begin Phase 2 testing at AEDC," said David Tweedie, general manager of advanced combat engines at GE Edison Works. "We continue to reduce risk through comprehensive engine testing, which is why the XA100 is the lowest risk, most capable and fastest way to keep the F-35 as a superior fighter platform for the long term."

GE's XA100 became the world's first flight-weight, three-flow, adaptive-cycle engine in December 2020, before starting testing of its second engine in August 2021. GE's engines are uniquely designed to fit both the F-35A and F-35C without requiring any structural modifications to either airframe for better aircraft range, acceleration and cooling for next-generation mission systems.
