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.
cpuinfo consists of an API/library used by programs to get information about the underlying CPU. Such information includes CPU vendor, model name, cache hierarchy, and supported features (e.g. CMP, SMT, and SIMD). cpuinfo is also a standalone program to demonstrate the use of this API.
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.
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.
