The reference likely pertains to the (often designated as Figure 7 in related documentation). This system is designed to run Large Language Models (LLMs) without expensive GPUs by using Compute Express Link (CXL) technology.

PIM Is All You Need: A CXL-Enabled GPU-Free System ... - arXiv

PIM is a computing paradigm where data processing occurs directly within the memory chips (like DRAM) rather than moving it back and forth to a central CPU or GPU. This eliminates the "memory wall"—the performance bottleneck caused by the slow and energy-intensive transfer of data between memory and processors. 2. The CENT Architecture

: Utilizing CXL 3.0 allows the system to support up to 4,096 nodes, which is significantly more scalable than proprietary interconnects like NVIDIA's NVLink.

: Units located near the memory chips that handle intensive computations, such as transformer block operations. 3. Key Advantages of this System

The identifier appears to be a specific figure or asset reference from technical literature regarding Processing-In-Memory (PIM) technologies, specifically within the context of the "CENT" architecture described in recent research papers like PIM Is All You Need .

: CXL-based memory expansion offers approximately 8x lower latency compared to network-based RDMA (Remote Direct Memory Access).

: A 2MB buffer on each device receives "CENT instructions" from a host CPU. These are then decoded into micro-ops for the memory units.
