Nvidia adds pre-trained models to TAO toolkit to boost AI development  

The latest version of Nvidia’s TAO toolkit boosts developer productivity with the addition of AutoML capability, integration with third-party MLOPs (machine learning operations) services and new pre-trained vision AI models. The enterprise version now includes access to the full source code and model weights for pretrained models.

The toolkit is designed for efficient model training for vision and conversational AI. By simplifying complex AI models and deep learning frameworks, Nvidia said even developers without AI expertise can use the toolkit to produce AI models. Users can optimise model inference throughput with AI expertise or large training datasets using transfer learning to fine-tune Nvidia pre-trained models with developer’s own data. Models can be trained without the hassle of manually fine-tuning hundreds of parameters.

Other enhancements are access to virtual models from leading cloud providers and Kubernetes services like Amazon EKS or Azure AKS. It is also possible to simplify infrastructure management and scaling on cloud machine learning services such as Google Colab, Google Vertex AI, and Microsoft Azure Machine Learning.

Nvidia also announced new cloud integrations and third-party MLOps services, such as W&B and ClearML, to provide developers and enterprises with an optimised AI workflow. It is possible to build a new AI service or integrate into an existing one with REST APIs.

Developers can also create custom production-ready models optimised for specific environments and scenarios with TAO. Transformer-based pre-trained models (CitySemSegformer, Peoplenet Transformer) and retail-specific pre-trained models (RetailObjectDetection, RetailObjectRecognition, and ReIdentificationNet) can be accessed.

Nvidia highlighted a new feature which helps developers build object detection models without massive amounts of data. The use cases include detecting assembly line defects, translating particular phrases across languages, or managing city traffic.

Ventana launches RISC-V CPU for data centres at RISC-V Summit

At this week’s RISC-V Summit in San Jose, California, Ventana Micro Systems introduced Veyron V1. The data centre class RISC-V CPU runs at 3.6GHz and will be offered in the form of high performance chiplets and IP. 

The Veyron V1 is the first RISC-V processor to provide single thread performance that is competitive with the latest incumbent processors for data centre, automotive, 5G, AI and client applications, claimed Ventana Micro Systems. Its efficient microarchitecture also enables the highest single socket performance among competing architectures, said the company.

The efficient performance of the Veyron, combined with RISC-V’s open and extensible architecture optimises the workload for efficiency gains which are enhanced further through domain specific acceleration that will extend Moore’s Law to deal with the emerging energy and thermal constraints for data centres, the company said.

The standards-based Veyron V1 compute chiplet and reference platform are claimed to accelerate time to market by up to two years and reduce development costs by up to 75 per cent. Chiplet based solutions provide flexibility and are economical by right sizing compute, IO and memory while composable architectures leveraging chiplets allow companies to focus on innovation. 

Ventana provides a software development kit (SDK) which includes an extensive set of software building blocks already proven on Ventana’s RISC-V platform.

The RISC-V CPU core is the centrepiece of the first compute chiplet solution with chiplets supplied by different companies. Ventana’s Veyron platform also enables integration of a flexible domain specific accelerator for hardware / software codesign. 

Veyron V1 will be available in the second half of 2023 and is the first in a series of products from Ventana.

“Ventana has a world class team with an average of twenty plus years of experience bringing multiple new CPU architectures to market,” said Patrick Moorhead, founder and chief analyst at Moor Insights & Strategy. “Ventana is the first big core in RISC-V to show up, the only game in town, and has a jump on the market.”

Key features include a 5nm process technology, 16 cores per cluster and a high core count multi-cluster scalability up to 128 cores. There is 48Mbyte of shared L3 cache per cluster, advanced side channel attack mitigation for cybersecurity and I/O memory management and advanced interrupt architecture (AIA) system IP.

Ventec introduces hydrocarbon laminate for RF and microwave applications

Expanding its hydrocarbon PCB laminate range, Ventec International introduces a new material for RF and microwave applications. The tec-speed 20.0 VTM1000i hydrocarbon laminate is the latest addition to the tec-speed 20.0 range of hydrocarbon-based PCB materials. It offers a level of thermal reliability and high Dk (9.8) and low Df (0.0023) that is typically seen only in PTFE materials, said the company. The new hydrocarbon laminate is a lower budget laminate for high-end RF applications, including satellite communications and 5G RF applications, said Ventec International.

Designed for antenna and communication systems, radar and aviation systems, tec-speed 20.0 VTM1000i is available in a range of dielectric thickness, from 0.38 to 3.81mm. It offers high decomposition temperature (Td) of 426 degrees C.

With regards to power integrity, the high Dk value (9.8 ± 0.0245 at 10Ghz) provides larger interplanar capacitance than other hydrocarbon laminates in this range, claimed Ventec.  

Manufactured at Ventec’s state-of-the-art facilities based in Taiwan and China, tec-speed 20.0 VTM1000i is available worldwide via Ventec’s managed global supply chain, providing reliable, disruption-free delivery in Asia, Europe, and the Americas, said the company.

tec-speed 20.0 VTM1000i will debut at the IPC APEX Expo 2023 in San Diego, California, USA (24 to 26 January 2023) on booth 419.

Ventec International produces polyimide and high-reliability epoxy laminates and prepregs and is a specialist provider of thermal management and IMS solutions.

OSFP-VLC is the first VCL-compatible connector, says Yamaichi 

A vertical version of the octal small form factor pluggable connector, the standard for optical transceivers and fibres in communications equipment, has been developed by Yamaichi Electronics. The OSFP-VLC is compatible with the VLC (vertical line card) and will debut at DesignCon 2023 (January 31 to February 02) in Santa Clara, California, USA.

The VLC architecture allows higher transmission speed with higher density by a vertical line card which mounts vertical I/O connectors and ASIC side by side to shorten the signal trace distance within three to four inches. It is compatible with mature technology (module, board assembly process and signal transmission technology) available in the market, said Yamaichi.

Using VLC can shorten the PCB line length in comparison to the conventional horizontal line card (HLC) option, added the company, yet 112G transmission can be achieved without increasing costs. In addition, vertical line card placement will decrease the number of boards needed, as well as make room for a cooling space which leads to much lower power consumption and increased cooling efficiency.

As 5G technology, big data, AI and IoT become more prevalent, it is becoming more important to have a fast and reliable connection in order to process extremely large amount of data in the cloud. On the other hand, cost reduction is becoming crucial for data centres which have to juggle maintaining physical space, air conditioning and efficient power consumption for the system.

There have been several proposals to realise higher transmission speed and density to upgrade data centre devices from 112G to 224G but these require new technology which increases production cost.

Yamaichi Electronics has collaborated with Nubis Communications to provide a connector based on VLC architecture which places OSFP connectors vertical to the line card. As a result, existing technology (module, mounting and signal transmission) can achieve higher signal density and speed while maintaining low cost and providing an efficient cooling structure for lower power consumption. As well as increased data transmission rates, cost savings with the elimination of cables and reduction in the number of boards needed and efficient cooling to lower power consumption, VLC enables the use of other I/O interface types.

Typical applications are optical transceiver devices, supercomputers as well as server, router and switches for data centres.
