Introduction

Open WebUI and Ollama are powerful tools that allow you to create a local chat experience using GPT models. Whether you’re experimenting with natural language understanding or building your own conversational AI, these tools provide a user-friendly interface for interacting with language models. In this guide, we’ll walk you through the installation process step by step.

Ollama is a cutting-edge platform designed to run open-source large language models locally on your machine. It simplifies the complexities involved in deploying and managing these models, making it an attractive choice for researchers, developers, and anyone who wants to experiment with language models1. Ollama provides a user-friendly interface for running large language models (LLMs) locally, specifically on MacOS and Linux (with Windows support on the horizon).

CXL Memory NUMA Node Mapping with Sub-NUMA Clustering (SNC) on Linux

• Steve Scargall
• Linux , Cxl

CXL (Compute Express Link) memory devices are revolutionizing server architectures, but they also introduce new NUMA complexity, especially when advanced memory configurations, such as Sub-NUMA Clustering (SNC), are enabled. One of the most confusing issues is the mismatch between NUMA node numbers reported by CXL sysfs attributes and those used by Linux memory management tools.

This blog post walks through a real-world scenario, complete with command outputs and diagrams, to help you understand and resolve the CXL NUMA node mapping issue with SNC enabled.

How To Install and Boot Microsoft Windows Server 2019 from Persistent Memory

• How to

In a previous post  I described how to install and boot Fedora Linux using only Persistent Memory, no SSDs are required. For this follow on post, I attempted to install Microsoft Windows Server 2019 and 2022 onto the persistent memory.

TL;DR - I was able to select the PMem devices as the install disk, but when the installer begins to write data, we get an “Error code: 0xC0000005”. I haven’t found a solution to this problem (yet).
