IBM Research has unveiled a significant advancement in optical interconnect technology for advanced data center communications. The breakthrough centers on a novel co-packaged optics (CPO) system featuring a sophisticated Polymer Optical Waveguide (PWG) design, marking a potential shift from traditional copper-based interconnects. The innovation introduces a Photonic Integrated Circuit (PIC) measuring 8x10mm, mounted on a 17x17mm substrate, capable of converting electrical signals to optical ones and vice versa. The system's waveguide, spanning 12 mm in width, efficiently channels light waves through precisely engineered pathways, with channels converging from 250 to 50 micrometers.

While current copper-based solutions like NVIDIA's NVLink offer impressive 1.8 TB/s bandwidth rates, and Intel's Optical Compute Interconnect achieves 4 TBit/s bidirectional throughput, IBM's technology focuses on scalability and efficiency. The company plans to implement 12 carrier waves initially, with the potential to accommodate up to 32 waves by reducing spacing to 18 micrometers. Furthermore, the design allows for vertical stacking of up to four PWGs, potentially enabling 128 transmission channels. The technology has undergone rigorous JEDEC-standard testing, including 1,000 cycles of thermal stress between -40°C and 125°C, and extended exposure to extreme conditions including 85% humidity at 85°C. The components have also proven reliable during thousand-hour storage tests at various temperature extremes. The bandwidth of the CPO is currently unknown, but we expect it to surpass current solutions.

Synopsys, Inc. today announced the industry's first Ultra Ethernet IP and UALink IP solutions, including controllers, PHYs, and verification IP, to meet the demand for standards-based, high-bandwidth, and low-latency HPC and AI accelerator interconnects.

Broadcom Inc. today announced the availability of its 3.5D eXtreme Dimension System in Package (XDSiP) platform technology, enabling consumer AI customers to develop next-generation custom accelerators (XPUs). The 3.5D XDSiP integrates more than 6000 mm² of silicon and up to 12 high bandwidth memory (HBM) stacks in one packaged device to enable high-efficiency, low-power computing for AI at scale. Broadcom has achieved a significant milestone by developing and launching the industry's first Face-to-Face (F2F) 3.5D XPU.

The immense computational power required for training generative AI models relies on massive clusters of 100,000 growing to 1 million XPUs. These XPUs demand increasingly sophisticated integration of compute, memory, and I/O capabilities to achieve the necessary performance while minimizing power consumption and cost. Traditional methods like Moore's Law and process scaling are struggling to keep up with these demands. Therefore, advanced system-in-package (SiP) integration is becoming crucial for next-generation XPUs. Over the past decade, 2.5D integration, which involves integrating multiple chiplets up to 2500 mm² of silicon and HBM modules up to 8 HBMs on an interposer, has proven valuable for XPU development. However, as new and increasingly complex LLMs are introduced, their training necessitates 3D silicon stacking for better size, power, and cost. Consequently, 3.5D integration, which combines 3D silicon stacking with 2.5D packaging, is poised to become the technology of choice for next-generation XPUs in the coming decade.

Marvell Technology, Inc., a leader in data infrastructure semiconductor solutions, today introduced Marvell Ara, the industry's first 3 nm 1.6 Tbps PAM4 interconnects platform featuring 200 Gbps electrical and optical interfaces.

AMD is reported to be forming plans for its Instinct MI400 Accelerator series, according to a leaked internal email. This information was shared by a hardware tipster (HXL/@9550Pro) on Twitter, but their post has been deleted as some point today. Wccftech was quick enough to note down the details, and their report suggests that AMD is already making plans for an APU range that is set to succeed the unreleased Instinct MI300 lineup (expected later in 2023). Instinct MI400 accelerators are touted to drive next generation data center and cloud platforms.

The leaked email email contained information about three upcoming products: Weisshorn, MI450 and XSwitch. Kepler's recent tweet posits that Weisshorn is AMD's in-house moniker for Zen 6 "Morpheus" architecture-based Venice CPUs - these are alleged to form part of an upcoming EPYC lineup (slated for 2025 or 2026). Hardware experts reckon that AMD will introduce a new interconnect fabric with the MI400 series - "XSwitch" is speculated to be the company's main technological answer to NVIDIA's NVLINK.

Eliyan Corporation, credited for the invention of the semiconductor industry's highest-performance and most efficient chiplet interconnect, today announced two major milestones in the commercialization of its technology for multi-die chiplet integration: the close of its Series A $40M funding round, and the successful tapeout of its technology on an industry standard 5-nanometer (nm) process.

Eliyan's NuLink PHY and NuGear technologies address the critical need for a commercially viable approach to enabling high performance and cost-effectiveness in the connection of homogeneous and heterogenous architectures on a standard, organic chip substrate. It has proven to achieve similar bandwidth, power efficiency, and latency as die-to-die implementations using advanced packaging technologies, but without the other drawbacks of specialized approaches.

When AMD announced that the company would deliver the world's fastest supercomputer, Frontier, the company also took a massive task to provide a machine capable of producing one ExaFLOP of total sustained ability to perform computing tasks. While the system is finally up and running, making a machine of that size run properly is challenging. In the world of High-Performance Computing, getting the hardware is only a portion of running the HPC center. In an interview with InsideHPC, Justin Whitt, program director for the Oak Ridge Leadership Computing Facility (OLCF), provided insight into what it is like to run the world's fastest supercomputer and what kinds of issues it is facing.

The Frontier system is powered by AMD EPYC 7A53s "Trento" 64-core 2.0 GHz CPUs and Instinct MI250X GPUs. Interconnecting everything is the HPE (Cray) Slingshot 64-port switch, which is responsible for sending data in and out of compute blades. The recent interview points out a rather interesting finding: exactly AMD Instinct MI250X GPUs and Slingshot interconnect cause hardware troubles for the Frontier. "It's mostly issues of scale coupled with the breadth of applications, so the issues we're encountering mostly relate to running very, very large jobs using the entire system … and getting all the hardware to work in concert to do that," says Justin Whitt. In addition to the limits of scale "The issues span lots of different categories, the GPUs are just one. A lot of challenges are focused around those, but that's not the majority of the challenges that we're seeing," he said. "It's a pretty good spread among common culprits of parts failures that have been a big part of it. I don't think that at this point that we have a lot of concern over the AMD products. We're dealing with a lot of the early-life kind of things we've seen with other machines that we've deployed, so it's nothing too out of the ordinary."

Based on a report by Tom's Hardware, AMD's CEO Lisa Su is planning a trip to Taiwan in the next couple of months. It is said that she is planning to meet with multiple partners in Taiwan, such as ASUS, Acer and maybe more importantly, ASMedia, which will be the sole maker of chipsets for AMD, once the X570 chipset is discontinued. AMD is apparently also seeing various less well known partners that deliver parts for its CPUs, such as Nan Ya PCB, Unimicron Technologies and Kinsus Interconnects.

However, it appears that the main reason for Lisa Su herself to visit Taiwan will be to meet with TSMC, to discuss future collaboration with CC Wei, TSMC's chief executive. This is so AMD can secure enough wafer allocation on future nodes, such as its 3 nm and 2 nm class nodes. The move to these nodes is obviously not happening in the near future for AMD, but considering that TSMC is currently the leading foundry and is operating at capacity, it makes sense to get in early, as the competition is stiff when it comes to getting wafer allocation on cutting edge nodes. It's unclear which exact 3 nm class node AMD will be aiming for, but it might be the N3P node, which is said to kick off production sometime next year. Lisa Su is also said to have meetings with TSMC, SPIL and Ase Technology when it comes to advanced packaging for AMD's products. This includes technologies such as chip-on-wafer-on-substrate (CoWoS) and fan-out embedded bridge (FO-EB), with AMD already being expected to use some of these technologies in its upcoming Navi 3x GPUs.
