Expanding the system's computing capability with an additional accelerator like a GPU is common. However, expanding the system's memory capacity with room for more DIMM is something new. Thanks to ServeTheHome, we see that at the OCP Summit 2024, Lenovo showcased its ThinkSystem SR860 V3 server, leveraging CXL technology and Astera Labs Leo memory controllers to accommodate a staggering 16 TB of DDR5 memory across 128 DIMM slots. Traditional four-socket servers face limitations due to the memory channels supported by Intel Xeon processors. With each CPU supporting up to 16 DDR5 DIMMs, a four-socket configuration maxes out at 64 DIMMs, equating to 8 TB when using 128 GB RDIMMs. Lenovo's new approach expands this ceiling significantly by incorporating an additional 64 DIMM slots through CXL memory expansion.

The ThinkSystem SR860 V3 integrates Astera Labs Leo controllers to enable the CXL-connected DIMMs. These controllers manage up to four DDR5 DIMMs each, resulting in a layered memory design. The chassis base houses four Xeon processors, each linked to 16 directly connected DIMMs, while the upper section—called the "memory forest"—houses the additional CXL-enabled DIMMs. Beyond memory capabilities, the server supports up to four double-width GPUs, making it also a solution for high-performance computing and AI workloads. This design caters to scale-up applications requiring vast memory resources, such as large-scale database management, and allows the resources to stay in memory instead of waiting on storage. CXL-based memory architectures are expected to become more common next year. Future developments may see even larger systems with shared memory pools, enabling dynamic allocation across multiple servers. For more pictures and video walkthrough, check out ServeTheHome's post.

At Lenovo Tech World 2024, we announced new Supercomputing servers for HPC and AI workloads. These new water-cooled servers use the latest processor and accelerator technology from Intel and NVIDIA.

ThinkSystem SC750 V4
Engineered for large-scale cloud infrastructures and High Performance Computing (HPC), the Lenovo ThinkSystem SC750 V4 Neptune excels in intensive simulations and complex modeling. It's designed to handle technical computing, grid deployments, and analytics workloads in various fields such as research, life sciences, energy, engineering, and financial simulation.

Today, Lenovo announced its industry-leading ThinkSystem infrastructure solutions powered by AMD EPYC 9005 Series processors, as well as AMD Instinct MI325X accelerators. Backed by 225 of AMD's world-record performance benchmarks, the Lenovo ThinkSystem servers deliver an unparalleled combination of AMD technology-based performance and efficiency to tackle today's most demanding edge-to-cloud workloads, including AI training, inferencing and modeling.

"Lenovo is helping organizations of all sizes and across various industries achieve AI-powered business transformations," said Vlad Rozanovich, Senior Vice President, Lenovo Infrastructure Solutions Group. "Not only do we deliver unmatched performance, we offer the right mix of solutions to change the economics of AI and give customers faster time-to-value and improved total value of ownership."

Lenovo Group Limited, together with its subsidiaries ("the Group"), today announced third quarter results reporting Group revenue increasing 3% year-on-year to US$15.7 billion, and Group profitability improving quarter-to-quarter for the second time in a row. Net income was US$357 million on a non-Hong Kong Financial Reporting Standards basis, with net income margin up 0.4% quarter-to-quarter to 2.3%. The Group's diversified growth engines continued to deliver strong performance, with revenue from non-PC businesses accounting for 42% of Group revenue, up 1.3 points year-on-year.

The consistent quarter-to-quarter improvements over past quarters have been driven by the resilience of the Group's core businesses and the wider effectiveness of its ongoing transformation. The SSG business hit an important milestone of passing the US$2 billion revenue threshold, achieved a record high operating profit with operating margin of over 20% and grew revenue from managed services and project and solution services year-on-year for 11 straight quarters. The ISG business delivered quarter-to-quarter revenue growth and reached a record high US$1 billion revenue for its storage, software, and services businesses. Overall, the IDG business resumed revenue growth, outperformed the market and achieved year-on-year shipment growth for PCs, and maintained its industry-leading profitability.

Lenovo (HKSE: 992) (ADR: LNVGY) has today announced that the General Purpose Partition of the MareNostrum 5, a new pre-exascale supercomputer running on Lenovo's HPC infrastructure, has been classified as the top x86 general-purpose cluster on the recently published TOP500 list of the most powerful supercomputers globally.

Officially inaugurated at Barcelona Supercomputing Center on December 21st, MareNostrum 5 has been built for the European High Performance Computing Joint Undertaking (EuroHPC JU). The pre-exascale supercomputer will bolster the EU's mission to provide Europe with the most advanced supercomputing technology and accelerate the capacity for artificial intelligence (AI) research, enabling new scientific advances that will help solve global challenges. It aims to empower a wide range of complex HPC-specific applications, from climate research and engineering to material science and earth sciences, adeptly handling tasks that extend beyond the capabilities of cloud computing.

The 62nd edition of the TOP500 reveals that the Frontier system retains its top spot and is still the only exascale machine on the list. However, five new or upgraded systems have shaken up the Top 10.

Housed at the Oak Ridge National Laboratory (ORNL) in Tennessee, USA, Frontier leads the pack with an HPL score of 1.194 EFlop/s - unchanged from the June 2023 list. Frontier utilizes AMD EPYC 64C 2GHz processors and is based on the latest HPE Cray EX235a architecture. The system has a total of 8,699,904 combined CPU and GPU cores. Additionally, Frontier has an impressive power efficiency rating of 52.59 GFlops/watt and relies on HPE's Slingshot 11 network for data transfer.

Today, AMD announced the extension of its 3rd Gen AMD EPYC processor family with six new offerings providing a robust suite of data center CPUs to meet the needs of general IT and mainstream computing for businesses seeking to leverage the economics of established platforms. The complete family of 3rd Gen AMD EPYC CPUs complements the leadership performance and efficiency of the latest 4th Gen AMD EPYC processors with impressive price-performance, modern security features and energy efficiency for less technically demanding business critical workloads.

The race to deliver AI and high performance computing is creating a technology gap for IT decision-makers seeking mainstream performance. To meet the growing demand for widely deployed, cost effective and proven mainstream solutions in the mid-market and in the channel, AMD is extending the 3rd Gen EPYC CPU offering to provide excellent value, performance, energy efficiency and security features for business-critical applications. The 3rd Gen AMD EPYC CPU portfolio enables a wide array of broadly deployed enterprise server solutions, supported by trusted channel sellers and OEMs such as Cisco, Dell Technologies, Gigabyte, HPE, Lenovo and Supermicro.

Lenovo and NVIDIA today announced an expansion of their partnership with new, hybrid solutions and engineering collaboration that supports their shared vision to bring the power of generative AI to every enterprise. In close collaboration with NVIDIA, Lenovo will deliver fully integrated systems that bring AI-powered computing to everywhere data is created, from the edge to the cloud, helping businesses easily deploy tailored generative AI applications to drive innovation and transformation across any industry.

The offerings were described by Lenovo Chairman and CEO Yuanqing Yang and NVIDIA founder and CEO Jensen Huang at the annual global Lenovo Tech World keynote held in Austin, Texas, where they discussed businesses' need for end-to-end solutions that bring together accelerated systems, AI software and expert services to quickly build and run custom AI models using their own data. Supported by the new Lenovo AI Professional Services Practice, the solutions enable enterprises to use a hybrid cloud approach - building their custom AI models using NVIDIA AI Foundations cloud service and then running them with on-prem Lenovo systems powered by NVIDIA's latest hardware and software designed for generative AI.
