GPUs Can Now Leverage PCIe Memory And SSDs To Increase VRAM Capacity — Panmnesia’s CXL IP Promises Big Gains

GPUs are leveraging PCIe memory and SSDs to supplement their VRAM capacity, thanks to Panmnesia’s innovative CXL IP technology. Panmnesia’s solution promises significant performance gains and cost efficiency for memory expansion in various computing environments.

Short Summary:

  • Panmnesia unveiled a CXL controller with industry-leading low latency.
  • The CXL IP enables scalable and cost-efficient memory expansion.
  • CXL-GPU solution significantly enhances GPU memory capacity and performance.

A Breakthrough in Memory Expansion Technology

In the fast-moving world of large-scale computing applications, efficient memory management is paramount. Panmnesia, Inc., an IP provider, has unveiled a Compute Express Link (CXL) controller, claiming it offers a groundbreaking two-digit nanosecond latency. The company’s proprietary CXL ASIC IP showcases latency metrics shorter than any other reported values to date.

“Our CXL Controller IP optimizes operations across all relevant layers, from the physical layer to the transaction layer, to achieve unparalleled low latency,” says a Panmnesia representative.

Cost-Efficient Memory Expansion

For data centers and services relying on large language models (LLMs) and similar applications, the memory requirement scale is relentlessly increasing. To meet these demands cost-effectively, CXL has emerged as an essential interconnect technology. This method enables the construction of a scalable, integrated memory system by linking various devices.

“CXL allows us to add memory resources based on demand and hidden integration, automating memory management tasks at the hardware level,” states a tech expert.

A Closer Look at Panmnesia’s CXL Controller IP

Latency is a critical factor for the real-world application of CXL in memory expansion. It aims to enhance GPU memory without significant performance degradation. Panmnesia’s breakthrough addresses this concern directly. Their IP showcases unmatched round-trip latency, making it a crucial component for next-gen memory expansion solutions.

This low latency, hardware-automated system seamlessly handles memory management operations. It can be applied to a diverse array of system devices, such as CPUs, switches, accelerators, and memory expanders. By integrating Panmnesia’s advanced CXL controller, organizations can achieve optimal memory expansion for a lower total cost of ownership (TCO) while maintaining high performance.

The CXL-GPU Solution

The most exciting part of this announcement is Panmnesia’s introduction of ‘CXL-GPU,’ a GPU storage expansion solution that dramatically increases the GPU’s memory capacity while maintaining their performance metrics. This robust system links multiple storage devices through CXL, forming a terabyte-scale memory space within the GPU memory configuration.

“Our CXL-based GPU storage expansion solution ensures AI-service providers can considerably cut server construction costs,” shared Dr. Myoungsoo Jung, CEO of Panmnesia.

The real advantage here lies in cost efficiency. Traditional methods involve purchasing expensive, high-end GPUs to boost memory capacity. In contrast, Panmnesia’s CXL-GPU enables selective memory resource addition, based strictly on demand. The top-tier low-latency controller greatly minimizes any performance overheads by streamlining memory management during deployments in both GPU and storage devices.

Performance Metrics and Real-World Applications

Initial evaluations of the CXL-GPU prototype, which integrates Panmnesia’s CXL Controller IP with a custom GPU built on an open-source framework, are promising. Test results indicate that the CXL-GPU solution outperforms conventional GPU memory expansion techniques by an impressive factor of 3.23x. These metrics are not just numbers on paper but reflect real-world gains in environments like cloud computing and high-performance computing (HPC).

The Bigger Picture: Applications Beyond GPUs

While the primary target of this technology is GPU memory expansion, the applications are far-reaching. The low-latency CXL controller is seen as a key component in cloud computing and HPC for efficient memory management. These environments benefit immensely from the reduced TCO and improved performance metrics.

“This technology can extend beyond GPU memory capacity, playing a pivotal role in cloud computing and HPC,” emphasized Dr. Jung.

A Glimpse into the Future

Panmnesia’s innovation sets a new benchmark in memory technology. By unveiling such a highly-optimized CXL Controller and the pioneering CXL-GPU solution, they are opening doors to numerous possibilities for diverse industries. Attendees at the upcoming USENIX federated conferences and ACM HotStorage in Santa Clara, CA, will witness the official debut of these groundbreaking technologies.

In an industry where every nanosecond counts, Panmnesia’s advancements in low-latency memory expansion can pivot the GPU landscape for PC builders and tech enthusiasts. In this evolving computational world, keeping abreast of such key developments is not just interesting—it’s essential.
