hwloc provides command line tools and a C API to obtain the hierarchical map of key computing elements, such as: NUMA memory nodes, shared caches, processor sockets, processor cores, and processor "threads". hwloc also gathers various attributes such as cache and memory information, and is portable across a variety of different operating systems and platforms. hwloc primarily aims at helping high-performance computing (HPC) applications, but is also applicable to any project seeking to exploit code and/or data locality on modern computing platforms.
Hotplug2 is aimed at early Linux user space, i.e. initramfs or initrd, and possibly also at embedded devices (such as WRT-like routers) or very weak machines, such as 386/486. It connects to the uevent netlink socket and reads events. The application generally operates in two modes: dumb and smart.
I-Nex gathers information for hardware components available on your system and displays it using an user interface similar to the popular Windows tool CPU-Z. It can display information for CPU, GPU, Motherboard, Sound, Hard disks, RAM, Network, and USB, as well as some system information like the hostname, Linux distribution and version, Xorg, GCC, and GLX versions, and Linux Kernel. It can also generate a report on which you can select what to include and optionally send the report to a service such as Pastebin (and others). It also features an option to take a screenshot of the I-Nex window directly from the application.
IPMItool is a simple command-line interface to systems that support the Intelligent Platform Management Interface (IPMI) specification. It provides the ability to read the SDR and print sensor values, display the contents of the SEL, print FRU information, read and set LAN configuration parameters, perform remote chassis power control, and act as a serial over LAN client. It can work with IPMI-over-LAN (both version 1.5 and 2.0) interfaces as well as the system interface provided by a kernel driver such as OpenIPMI.
