Memory-mapped I/O - Wikipedia, The Free Encyclopedia memorymapped I/O uses the same bus to address both memory and I/O of their assigned address space, mapping the address to their hardware registers. http://en.wikipedia.org/wiki/Memory-mapped_I/O
Extractions: Memory-mapped I/O MMIO ) and port I/O (also called port-mapped I/O or PMIO ) are two complementary methods of performing input/output between the CPU and I/O devices in a computer . Another method is using dedicated I/O processors ( channels , used in IBM mainframe computers). Memory-mapped I/O uses the same bus to address both memory and I/O devices, and the CPU instructions used to read and write to memory are also used in accessing I/O devices. In order to accommodate the I/O devices, areas of CPU addressable space must be reserved for I/O rather than memory. This does not have to be permanent, for example the Commodore 64 could bank switch between its I/O devices and regular memory. The I/O devices monitor the CPU's address bus and respond to any CPU access of their assigned address space, mapping the address to their hardware registers Port-mapped I/O uses a special class of CPU instructions specifically for performing I/O. This is generally found on Intel microprocessors , specifically the IN and OUT instructions which can read and write a single byte to an I/O device. I/O devices have a separate address space from general memory, either accomplished by an extra "I/O" pin on the CPU's physical interface, or an entire

Apple - Hardware - Sleep Memory Extension To install the Sleep memory Extension, do the following. Download the extension. Doubleclick on the file named Sleep memory Extension.smi to open it. http://www.apple.com/hardware/articles/sleepext.html
Extractions: Apple has identified a bug in system software prior to Mac OS 9.0.4 which in very rare circumstances can prevent your computer from properly waking up from sleep. Though you will most likely never encounter this bug, we still recommend that all iBook and new PowerBook (FireWire) owners download and install the following Sleep Memory Extension software patch which eliminates this bug. (This patch is not necessary if your computer is running Mac OS 9.0.4 or later.) To install the Sleep Memory Extension, do the following: Download the extension. Double-click on the file named "Sleep Memory Extension.smi" to open it. Read the Software License Agreement and click "Agree." Double-click on the volume named "Sleep Memory Extension" to open it. Drag the Sleep Memory Extension onto the closed System Folder on your iBook or PowerBook (FireWire) hard disk. A dialog box asks if you would like to place the item in the Extensions Folder. Click Yes. Restart your computer. After restarting your computer, the "Preserve memory contents on sleep" checkbox will still appear in the Energy Saver control panel, but the checkbox will be dimmed and unavailable.
EXTREME Overclocking - Tweaking PC Hardware To The Max We have current computer news, hardware and software reviews, OCZ is probably best known for their high performance memory and accessories, however they http://www.extremeoverclocking.com/
Extractions: Sunbeamtech, a company often associated with enthusiast cases and accessories, has released a couple high-end modular power supplies. The NUUO 550W is not only NVIDIA SLI Certified, it is the first modular power supply to make their list. An extra feature of the NUUO series is a temperature monitor / fan controller device that mounts in a 3.5" drive bay. Jetart NP6600 Foldable Notebook Cooler Modern notebooks pack the same processing power as a desktop PC in only a fraction of the space. With components being packed so tightly together, heat buildup becomes a serious issue that designers have to contend with. Notebook coolers were designed as an attempt to aid in dissipating the large amounts of heat generated by notebooks. Antec TX1050B Black SOHO Tower Case Antec is one of the top most recognized brand names when it comes to high-end PC enclosures. The original Performance Series is undoubtedly the most well-known Antec design, and each new generation since then has been based on this classic chassis. The Antec TX1050B in this review is part of the Performance TX line, a third generation model. Meridian XCLIO Aurora+P Lighting Mouse Pad +USB
Hardware At OSC The current hardware configuration consists of the following The OSC Itanium 2 Cluster is distributed/shared memory hybrid of commodity systems based http://www.osc.edu/hpc/hardware/
Extractions: High Performance Computing Systems OSC CRAY X1 The CRAY X1 computer system at OSC is a powerful parallel vector processor (PVP) supercomputer that features 16 (800 MHz) Multi Streaming vector processors and 128 Gbytes of physical RAM for large simulations. Each MSP processor contains four internal processors called Single Streaming Processors (SSP). The SSPs are 800MHz vector processors and applications can be compiled to run on individual SSPs if desired. By default, applications are compiled to run on the MSP processors, which bind the 4 internal SSP processors together with special hardware registers to operate on the application.

Extractions: Systems with global shared memory allow access to all data in the system's memory directly and efficiently, without having to move data through I/O or networking bottlenecks. The impact can be dramatic. For example, the latency or 'wait times' for messages that must go through system I/O are on the order of 1000 to 10000 greater than communication within the memory domain. To overcome this, clusters without global shared memory must instead pass copies of data, often in the form of messages, which can greatly complicate programming and slow down performance by increasing the time processors must wait for data. Why does this matter? Users can do more and get results sooner. Entire databases can be driven directly out of memory. Hardware and software costs are lower. System administrators and users spend less time feeding and tuning the cluster. Developers have new flexibility to choose any programming model for application scalability. And it's all standards-based Linux. Read more about how SGI's customers and partners have already proven the benefits of Global Shared memory in a variety of industries.
