parkverbot is a daemon that prevents hard disk head parking in rotational media. Modern rotational hard disks have a misfeature involving the regular automatic unloading of the heads, measurable by the SMART attribute "Load_Cycle_Count". This causes latency on wake-up amongst other issues (and it cannot always be turned off). The parkverbot daemon will periodically issue small read requests in order to keep the hardware from going to its head-unloaded idle state.
amforth is an extendible command interpreter for the Atmel AVR ATmega microcontroller family. It has a turnkey feature for embedded use as well. It does not depend on a host application. The command language is an almost compatible ANS94 forth with extensions. It needs less than 8KB code memory for the base system. It is written in assembly language and forth itself.
Hwclock is a program that runs under Linux and sets and queries the Hardware Clock, which is often called the Real Time Clock, RTC, or CMOS clock. This is the program that most Linux systems use to get the time from the Hardware Clock and set the System Time at boot time. This program works on ISA (Intel), Alpha, SPARC, and M68K systems with or without /dev/rtc.
Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
check_hpasm is a plugin for Nagios which checks the hardware health of Hewlett-Packard Proliant servers. To accomplish this, you must have installed the hpasm package. The plugin checks the health of processors, power supplies, memory modules, fans, CPU- and board-temperatures, and alerts you if one of these components is faulty or operates outside its normal parameters.
