Making AMD GPUs competitive for LLM inference
MLC-LLM makes it possible to compile LLMs and deploy them on AMD GPUs using ROCm with competitive performance. More specifically, AMD Radeon™ RX 7900 XTX gives 80% of the speed of NVIDIA® GeForce RTX™ 4090 and 94% of the speed of NVIDIA® GeForce RTX™ 3090Ti for Llama2-7B/13B. Besides ROCm, our Vulkan support allows us…

Building Alex Taradov’s open-source USB sniffer
A couple of months ago I stumbled upon a post on Hackaday about an inexpensive open-source USB 2.0 sniffer created by Alex Taradov . This is a really cool project! Normally, USB sniffers like this can cost thousands of dollars, especially if you’re paying for fancy protocol decoding and also want high-speed 480 Mbps…

Why libvirt supports only 14 PCIe hotplugged devices on x86-64
You might have used libvirt , a Linux daemon that provides an abstraction and management layer for virtualization software. This daemon allows you to submit an XML file containing a description of a VM, disk image or network. libvirt is then able to configure, start it and keep it running.
