Caution Do not guess at values for Horiz Sync or Vert Refresh

The following section defines a monitor named MonitorO. The VendorName and ModelName are for reference only and do not affect the way the system works. The optional DisplaySize specifies the height and width of the screen in millimeters, allowing X to calculate the DPI of the monitor. HorizSync and VertRefresh specify ranges of vertical refresh frequencies and horizontal sync frequencies for the monitor these values are available from the manufacturer. The dpms Option specifies the monitor is DPMS (page 1030) compliant (has built-in energy-saving features).

The YaST Power Management Module

First, enter a suitable name and description for the new or edited scheme. For the hard disk, define a 'Standby Policy' for maximum performance or for energy saving. The 'Acoustic Policy' controls the noise level of the hard disk. Click 'Next' to enter the 'CPU' and 'Cooling Policy' dialog. 'CPU' comprises the options 'CPU Frequency Scaling' and 'Throttling'. Use these options to define if and to what extent the CPU frequency may be throttled. The 'Cooling Policy' determines the cooling method. Complete all settings for the scheme and click 'OK' to return to the start dialog (Figure 17.1 on the next page). In the start dialog, assign the custom scheme to one of the two operating modes. To activate your settings, exit this dialog with 'OK'.

Choosing More Efficient Power Management Options

On the On AC Power tab of the Power Management Preferences window, you can optimize your computer's power usage. These options apply only if your computer is connected to the electric grid you don't need these options if your computer is on battery power. Under Actions, you can specify when your computer should be put to sleep. The default setting is Never, which makes sense if you netbook is plugged in. To be more energy efficient, you can set this to, for example, one hour, which will suspend your computer when you're away. The second set of options relate to the graphical display. By default, your display goes to sleep after 30 minutes of inactivity, which in most cases is reasonable. To continue working, press any key, and the display will wake up. You can also set the display brightness. By default, it's as bright as possible. If you don't like that, use the slide bar to diminish the brightness setting. If you want to be more energy efficient, select the Dim display when idle...

Favorite Green Linux Product Or Solution

Because virtualization is such a fabulous and popular way to improve the efficiency of your servers, VMware landed the top spot in the Favorite Green Linux Product or Solution category. The PowerTOP tool for finding energy wasters on your systems also is popular and won an honorable mention at 16.3 . Although many readers earnestly consider energy consumption and environmental impacts in their data-center strategy, we were surprised to see the high number of responses like Hummer and I promote global warming. We wonder with concern, How much good science is necessary to convince us of the seriousness of our environmental challenges

Ubuntu Netbook Edition

Ubuntu Netbook Edition is a version of Ubuntu designed specifically for netbook computers. It is optimized for computing devices with small screens and limited resources (like the energy-saving processors and smaller hard disks common among netbooks). Ubuntu Netbook Edition sports a unique interface and features a collection of software applications particularly useful to on-the-go users.

Using Multiple House Codes

This is by far the most common type of device, and accordingly there are several different devices to choose from, all known in X10 parlance as lamp modules. However, it should be noted that some lights cannot be attached to lamp modules at all. These include the fluorescent lighting strips found in most kitchens and their compact fluorescent lamp equivalents (often known as energy-saving bulbs) now making their appearances in homes around the country. To make matters worse, these bulbs can also introduce spikes on the power line that can turn off nearby X10 lights.2 This is also a simple zero-installation device but one that requires slightly more configuration. To install it, you plug it into an existing light socket and then reinsert the bulb (up to 150W) into its free end. Neither fluorescent lamps nor low-energy lamps should be used, though. The address is set by turning the lamp off and on again and then pressing the required house unit code on the controller three times, once a...

Improving Disk Performance

If Linux isn't running your disks in an optimal mode, you can use hdparm to adjust its settings. In some cases, you can apply driver-specific options to your ATA driver. Finally, one issue of disk performance doesn't relate to speed, but it is important to laptop users energy use. You can configure the disks to spin down when they haven't been accessed for some time, thereby saving energy. Normally, a computer's hard disks spin whenever the computer is turned on. This feature makes disk access swift, because there's no need to begin spinning the disk to access a file however, it consumes a fair amount of power. Therefore, as an energy-saving measure, spinning down a disk when it's not in use is sometimes desirable. Doing so is particularly helpful on laptop computers, on which a spinning hard disk can greatly reduce battery life. Therefore, hdparm supports the -S option to set this feature. Unfortunately, the encoding of this feature is rather odd, as outlined in Table 2.4. You can...

Summary

Power management is an essential job on portable computers. At the core of power management is an understanding of how to effectively optimize energy consumption of each system component. This entails studying the different tasks that your system performs, and configuring each component to ensure that its performance is just right for the job.

Power Management

Many types of embedded devices have different power requirements depending on their usage. For example, network routers need to have minimal energy consumption to avoid heating, especially when used under rugged conditions. Devices such as PDAs and cell phones need to consume less energy so that battery life is not cut short. This section explains the power management schemes available under Linux for embedded systems and the power management framework on Linux, which spans across the BSP, drivers, and application layers. But before that we discuss the nexus between hardware design and power management.

Human Considerations

Your house and allowing the heat to rise1 can provide any reasonable savings on your bills. The downside of this excess heat is that it might get very uncomfortable to work on the machines in Node0 if they're in an enclosed space that is heating up by the second. Consequently, install only low-energy or fluorescent lights here to prevent it from heating up any further when you're working on it.

Desktop PC

The Mini-ITX is a family of machines based around the 170 x170mm ITX motherboard. Within this specification, there are a number of different options with varying processors, graphics chips, and cooling methodologies. This includes many machines that are fanless, relying only on the heat sink for cooling. This makes them more energy efficient than their desktop counterparts and suitable for placing in more communal areas, such as the living room where they are often used as media players.

Hardware

Although you may not yet find preinstalled Linux too easily at your neighborhood computer superstore, our beloved OS is bubbling up in more scintillating ways, including in the recently released Zonbu PC. Zonbu is a mini, fanless Gentoo Linux-driven PC that, with its on-line storage (sans hard drive ), functions with a computing as a service ethos. In addition, Zonbu is one of the few PCs that markets its green street cred, aiming to provide us concerned citizens with a means to reduce our energy consumption and thus our impact on the environment.

Eideata Problems

-S timeout This option sets an energy-saving option the time a drive will wait without any accesses before it enters a low-power state. It takes a few seconds for a drive to recover from such a state, so many desktops leave timeout at 0, which disables this feature. On laptop computers, though, you may want to set timeout to something else. Values between 1 and 240 are multiples of 5 seconds (for instance, 10 means a 50-second delay) 241-251 mean 1-11 units of 30 minutes 252 is a 21-minute timeout 2 53 is a drive-specific timeout and 2 55 is a 21-minute and 15-second timeout.

FramaC

Frama-C (http frama-c.cea.fr ) is an open-source toolbox combining several existing static analysis techniques and applying them to the C language. It was developed and used by the Research Centre of CEA (French Nuclear Energy Agency) during the European OPENTC FP6 1ST project (http www.opentc.net ) to analyze parts of the Xen hypervisor. Its strength resides in a memory model that is well adapted to embedded code. It currently combines results obtained through abstract interpretation and Hoare Logics techniques. Few of these tools, apart from Coverity, have analyzed general-purpose

Caveat

Caveat is a purely static analysis tool for the C language, devoted to embedded applications. Caveat was developed by the Research Centre of CEA (French Nuclear Energy Agency). It contains a predicates language, a VC generator, and a proof tool to discharge them. For each function, the tool computes a weakest precondition based on some pre- and post-conditions. The advantage of the Hoare method is to give an exact result of the possibility of such errors occurring. The drawback is that it is sometimes necessary to provide loop invariants as well as hypotheses and additional information manually for trying to prove the presence or absence of errors. This makes the process interactive but allows you to understand the errors origins. Caveat is used by Airbus Industries.

Power Control

ThePower Control modules configure the energy-saving and battery settings for your system. The Energy module applies to all systems that have a monitor with energy-saving capabilities the remaining modules apply to laptop) or other battery-powered systems using the Linux Advanced Power Management (APM) or Advanced Configurati on and Power Interface (ACPI) features.

Linux Powers

Tippett chose Linux on Mac for many reasons. There's the ability to run multiple operating systems, including Linux, OS X and Windows, says Darling, and he continues, The systems are fast That makes for more productive artists. The hardware is quiet and energy-efficient. It's cost-effective, with a good cost per rendermark a renderfarm performance benchmark . It's standardized hardware. And, there's a good support plan. Although the majority of our workstations run Linux, we have a handful of other systems running to support specific software. We use the ability to boot in to other operating systems, Industry leading 4P x86 computing to boost performance and power efficiency with Dual or Quad-Core AMD Opteron Processors Quad-Core Ready - increase capacity without altering datacenter infrastructure Best performance per-watt with energy-efficient DDR2 Optimized system performance with Direct Connect Architecture

The System Menu

Power Management If you are using a laptop, you can use the Power Management settings to create energy-saving schemes. On a server that is always AC powered, it does not make sense to use this option. You would always want it set to the Performance scheme, which makes sure your server is performing in the most optimal way. In the Other Settings drop-down list, one option, however, is useful for servers the ACPU Buttons option. This option allows you to set the default behavior when a certain button is clicked on your server. For servers, only the Power Button option makes sense by default, clicking the power button on the server will shut down the server gracefully. Other options are available as well, as shown in Figure 3-9 you may want to consider setting the default action for clicking the power button on your server to something less interrupting than shutting down the complete system. For example, it is a good choice just to have your server ignore the power button being pressed...
