Accelerating Data Retrieval in Retrieval Augmentation Generation (RAG) Pipelines using CXL
RAG (retrieval augmented generation) has emerged as a powerful technique to customize LLMs for users and use cases beyond the model’s training set. However, there are multiple potential bottlenecks within a RAG pipeline.
Introducing Weighted Interleaving in Linux for Enhanced Memory Bandwidth Management
With the release of Linux Kernel 6.9, system administrators have gained a powerful new tool for managing memory distribution across NUMA nodes: Weighted Interleaving. This feature is especially beneficial in systems utilizing various types of memory, including traditional DRAM and Compute Express Link (CXL) attached memory. In this article, we’ll explore Weighted Interleaving, how it works, and how to use it.
Unleashing the Future of Memory Management: Exploring CXL Dynamic Capacity Devices with Docker and QEMU
In the ever-advancing realm of technology, developers and application owners always look for innovative tools and methodologies to boost performance and scalability. A revolutionary stride in this direction is the integration of Compute Express Link (CXL) technology, particularly through the utilization of Dynamic Capacity Devices (DCD). CXL, an open standard for high-speed CPU-to-device and CPU-to-memory interconnects, substantially enhances data center and cloud environments, offering many benefits.
Memory Wall, Big Memory, and the Era of AI
In the fast-evolving landscape of artificial intelligence (AI), where models are growing larger and more complex by the day, the demand for efficient processing of vast amounts of data has ushered in a new era of computing infrastructure.
Emulating CXL Memory Expanders in QEMU
Build and install a working branch of QEMU. Launch a pre-made QEMU instance with a CXL Memory Expander. Create a memory region for the CXL Memory Expander. Convert that memory region between DEVDAX and NUMA Modes.
Emulating CXL Shared Memory Devices in QEMU
Build and install a working branch of QEMU. Launch a pre-made QEMU lab with 2 hosts utilizing a shared memory device. Access the shared memory region through a devdax device, and share information between the two hosts to verify that the shared memory region is functioning.
The Dawn of the CXL Era
As the first server processor that will officially support the CXL 1.1+ memory interconnect, AMD 4th Gen EPYC Processors mark the beginning of the CXL era.
