Linux Kernel 6.14 is Released: This is What's New for Compute Express Link (CXL)

Using Linux Volume Manager (LVM) with Persistent Memory

• Steve Scargall
• How to , Linux

In this article, we show how to use the Linux Volume Manager (LVM) to create concatenated, striped, and mirrored logical volumes using persistent memory modules as the backing storage device. Specifically, we will be using the Intel® Optane™ Persistent Memory Modules on a two socket system with Intel® Cascade Lake Xeon® CPUs, also referred to as 2nd Generation Intel® Xeon® Scalable Processors.

• Orca slicer , 3 d printing

OrcaSlicer is a powerful and popular slicer for 3D printers, known for its rich feature set and active development community. In this blog post, we’ll take a closer look at a new feature I proposed and implemented that provides more insight into your prints: the display of total travel distance and the number of travel moves. See the feat: Display travel distance and move count in G-code summary for more details.

What is CXL?

Compute Express Link (CXL) is an open standard for high-speed central processing unit-to-device and CPU-to-memory connections, designed for high-performance data center computers. CXL is built on the PCI Express physical and electrical interface with protocols in three areas: input/output, memory, and cache coherence.

CXL is designed to be an industry open standard interface for high-speed communications, as accelerators are increasingly used to complement CPUs in support of emerging applications such as Artificial Intelligence and Machine Learning.
