: Each CXL device in this architecture integrates 16 controllers, each managing two GDDR6-PIM channels.
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 pim073.jpg
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. : Each CXL device in this architecture integrates
: 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. : Utilizing CXL 3
