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.
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.
Leevi is a user interface for the Lexicon MX300 reverberation device (and possibly other MX devices). It is similar to what Lexicon ships along with their devices for Windows operating systems. Leevi works with POSIX compatible operating environments, like Linux, FreeBSD, NetBSD, OpenBSD, and so on.
Rosetta Stone API aims to create a programming equivalent to the popular Unix Rosetta Stone, which gives commands for common tasks for many different flavors of Unix. RSApi is a Web page and library dedicated to getting system information out of different Unix platforms including Linux, Tru64, Solaris, HP-UX, and AIX.
SimMon is a cross platform monitoring tool which runs on almost any OS that supports the Java Virtual Machine 1.4+. Monitoring is done through the execution of existing monitoring scripts (Perl/VBS) or existing shell commands. Currently monitoring scripts are available for Solaris, Linux, Mac OS X, and Windows based systems. Network devices can be monitored via the integrated SNMPv1 scheduler.
