Self-install air conditioners use indoor and outdoor units that are no different to commercially installed units – it is the coupling between them that is different.

If you are looking for a cooling solution for the office, server room, warehouse or at home then a portable air conditioner is the solution – but just be aware of whats out there.

This is a common question that we get asked here at DiO and the answer is,new york escort like most things in life, yes and no. It depends on what you define as a portable air conditioner.

As so often happens in the UK Cameras, when we get warmer temperatures we also get a lot of moisture trapped in the air and this gives us a muggy, stifling atmosphere that is both unpleasant and strength-sapping to work and live in.

Multi-core processor

Since computer manucturers have long implemented symmetric multiprocessing (SMP) designs using discrete CPUs, the issues regarding implementing multi-core processor architecture and supporting it with software are well known.

The terms are generally used only to refer to multi-core microprocessors that are manuctured on the same integrated circuit die; separate microprocessor dies in the same package are generally referred to by another name, such as multi-chip module. This article uses the terms multi-core and dual-core for CPUs manuctured on the same integrated circuit, unless otherwise noted.

The improvement in performance gained by the use of a multi-core processor depends very much on the software algorithms used and their implementation. In particular, possible gains are limited by the fraction of the software that can be run in parallel simultaneously on multiple cores; this effect is described by Amdahls law. In the best case, so-called embarrassingly parallel problems may realize speedup ctors near the number of cores, or even more if the problem is split up enough to fit within each cores cache(s), avoiding use of much slower main system memory. Most applications, however, are not accelerated so much unless programmers invest a prohibitive amount of effort in re-ctoring the whole problem.

which simplifies multi-core development across game platforms. In addition, Apple Inc.s OS X, starting with Mac OS X Snow Leopard, and iOS starting with iOS 4, have a built-in multi-core cility called Grand Central Dispatch.

and Crytek has developed similar technologies for CryEngine 2, which powers their game, Crysis. engine includes their Floodgate technology,

Managing concurrency acquires a central role in developing parallel applications. The basic steps in designing parallel applications are:

Two types of operating systems are able to utilize a dual-CPU multiprocessor: partitioned multiprocessing and symmetric multiprocessing (SMP). In a partitioned architecture, each CPU boots into separate segments of physical memory and operate independently; in an SMP OS, processors work in a shared space, executing threads within the OS independently.

is a fully synthesizable multi-core container for ARM11 MPCore and ARM Cortex-A9 MPCore processor cores, intended for high-performance embedded and entertainment applications.

In digital signal processing the same trend applies: Texas Instruments has the three-core TMS320C6488 and four-core TMS320C5441, Freescale the four-core MSC8144 and six-core MSC8156 (and both have stated they are working on eight-core successors). Newer entries include the Storm-1 mily from Stream Processors, Inc with 40 and 80 general purpose ALUs per chip, all programmable in C as a SIMD engine and Picochip with three-hundred processors on a single die, focused on communication applications.

Parallel programming techniques can benefit from multiple cores directly. Some existing parallel programming models such as Cilk++, OpenMP, OpenHMPP, FastFlow, Skandium, MPI, and Erlang can be used on multi-core platforms. Intel introduced a new abstraction for C++ parallelism called TBB. Other research efforts include the Codeplay Sieve System, Crays Chapel, Suns Fortress, and IBMs X10.

Processors were originally developed with only one core. A dual-core processor has two cores (e.g. AMD Phenom II X2, Intel Core Duo), a quad-core processor contains four cores (e.g. AMD Phenom II X4, Intels quad-core processors, see i3, i5 Core, and i7 at Intel Core), a hexa-core processor contains six cores (e.g. AMD Phenom II X6, Intel Core i7 Extreme Edition 980X), an octo-core processor or octa-core processor contains eight cores (e.g. Intel Xeon E7-2820, AMD FX-8350), a deca-core processor contains ten cores (e.g. Intel Xeon E7-2850). A multi-core processor implements multiprocessing in a single physical package. Designers may couple cores in a multi-core device tightly or loosely. For example, cores may or may not share caches, and they may implement message passing or shared memory inter-core communication methods. Common network topologies to interconnect cores include bus, ring, two-dimensional mesh, and crossbar. Homogeneous multi-core systems include only identical cores, heterogeneous multi-core systems have cores that are not identical. Just as with single-processor systems, cores in multi-core systems may implement architectures such as superscalar, VLIW, vector processing, SIMD, or multithreading.

proprietary enterprise-server software is licensed per processor. When a CPU was a processor and most computers had only one CPU, there was no ambiguity.

While manucturing technology improves, reducing the size of individual gates, physical limits of semiconductor-based microelectronics have become a major design concern. These physical limitations can cause significant heat dissipation and data synchronization problems. Various other methods are used to improve CPU performance. Some instruction-level parallelism (ILP) methods such as are suitable for many applications, but are inefficient for others that contain difficult-to-predict code. Many applications are better suited to thread level parallelism (TLP) methods, and multiple independent CPUs are commonly used to increase a systems overall TLP. A combination of increased available space (due to refined manucturing processes) and the demand for increased TLP led to the development of multi-core CPUs.

Given the increasing emphasis on multi-core chip design, stemming from the grave thermal and power consumption problems posed by any further significant increase in processor clock speeds, the extent to which software can be multithreaded to take advantage of these new chips is likely to be the single greatest constraint on computer performance in the future. If developers are unable to design software to fully exploit the resources provided by multiple cores, then they will ultimately reach an insurmountable performance ceiling.

Diagram of a generic dual-core processor, with CPU-local level 1 caches, and a shared, on-die level 2 cache.

Additionally:

Oracle counts an AMD X2 or Intel dual-core CPU as a single processor but has other numbers for other types, especially for processors with more than two cores. IBM and HP count a multi-chip module as multiple processors. If multi-chip modules count as one processor, CPU makers have an incentive to make large expensive multi-chip modules so their customers save on software licensing.

The proximity of multiple CPU cores on the same die allows the cache coherency circuitry to operate at a much higher clock-rate than is possible if the signals have to travel off-chip. Combining equivalent CPUs on a single die significantly improves the performance of cache snoop (alternative: Bus snooping) operations. Put simply, this means that signals between different CPUs travel shorter distances, and therefore those signals degrade less. These higher-quality signals allow more data to be sent in a given time period, since individual signals can be shorter and do not need to be repeated as often.

Digital signal processors (DSPs) have utilized multi-core architectures for much longer than high-end general-purpose processors. A typical example of a DSP-specific implementation would be a combination of a RISC CPU and a DSP MPU. This allows for the design of products that require a general-purpose processor for user inteces and a DSP for real-time data processing; this type of design is common in mobile phones. In other applications, a growing number of companies have developed multi-core DSPs with very large numbers of processors.

The memory wall; the increasing gap between processor and memory speeds. This effect pushes cache sizes larger in order to mask the latency of memory. This helps only to the extent that memory bandwidth is not the bottleneck in performance.

[…] Anant Agarwal, founder and chief executive of startup Tilera, took the opposing view. He said multi-core chips need to be homogeneous collections of general-purpose cores to keep the software model .

As of 2010

The ILP wall; the increasing difficulty of finding enough parallelism in a single instructions stream to keep a high-performance single-core processor busy.

Integration of a multi-core chip drives chip production yields down and they are more difficult to manage thermally than lower-density single-chip designs. Intel has partially countered this first problem by creating its quad-core designs by combining two dual-core on a single die with a unified cache, hence any two working dual-core dies can be used, as opposed to producing four cores on a single die and requiring all four to work to produce a quad-core. From an architectural point of view, ultimately, single CPU designs may make better use of the silicon suce area than multiprocessing cores, so a development commitment to this architecture may carry the risk of obsolescence. Finally, raw processing power is not the only constraint on system performance. Two processing cores sharing the same system bus and memory bandwidth limits the real-world performance advantage. It has been claimed

Several business motives drive the development of dual-core architectures. For decades, it was possible to improve performance of a CPU by shrinking the area of the integrated circuit,new york asian escort model which drove down the cost per device on the IC. Alternatively, for the same circuit area, more transistors could be utilized in the design, which increased functionality, especially for CISC architectures. Clock rates also increased by orders of magnitude in the decades of the late 20th century, from several megahertz in the 1980s to several gigahertz in the early 2000s.

The instructions are ordinary CPU instructions such as add, move data, and branch, but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing.

, multi-core network processing devices have become mainstream, with companies such as Freescale Semiconductor, Cavium Networks, Wintegra and Broadcom all manucturing products with eight processors. For the system developer, a key challenge is how to exploit all the cores in these devices to achieve maximum networking performance at the system level, despite the performance limitations inherent in an SMP operating system. To address this issue, companies such as 6WIND provide portable packet processing software designed so that the networking data plane runs in a st path environment outside the OS, while retaining full compatibility with standard OS APIs.

In addition, embedded software is typically developed for a specific hardware release, issues of software portability, legacy code or supporting independent developers less critical than is the case for PC or enterprise computing. As a result, it is easier for developers to adopt new technologies and as a result there is a greater variety of multi-core processing architectures and suppliers.

that if a single core is close to being memory-bandwidth limited, then going to dual-core might give 30% to 70% improvement; if memory bandwidth is not a problem, then a 90% improvement can be expected; however, Amdahls law makes this claim dubious.

Assuming that the die can fit into the package, physically, the multi-core CPU designs require much less printed circuit board (PCB) space than do multi-chip SMP designs. Also, a dual-core processor uses slightly less power than two coupled single-core processors, principally because of the decreased power required to drive signals external to the chip. Furthermore, the cores share some circuitry, like the L2 cache and the intece to the front side bus (FSB). In terms of competing technologies for the available silicon die area, multi-core design can make use of proven CPU core library designs and produce a product with lower risk of design error than devising a new wider core-design. Also, adding more cache suffers from diminishing returns.

In the fourth and final stage of the design of parallel algorithms, the developers specify where each task is to execute. This mapping problem does not arise on uniprocessors or on shared-memory computers that provide automatic task scheduling.

The power wall; the trend of consuming exponentially increasing power with each ctorial increase of operating frequency. This increase can be mitigated by shrinking the processor by using smaller traces for the same logic. The power wall poses manucturing, system design and deployment problems that have not been justified in the ce of the diminished gains in performance due to the memory wall and ILP wall.

Maximizing the utilization of the computing resources provided by multi-core processors requires adjustments both to the operating system (OS) support and to existing application software. Also, the ability of multi-core processors to increase application performance depends on the use of multiple threads within applications. The situation is improving: for example the Valve Corporations Source engine offers multi-core support,

MPPA-256, 256-core processor, released 2012 (256 usable VLIW cores, Network-on-Chip (NoC), 32/64-bit IEEE 754 compliant FPU)

The general trend in processor development has moved from dual-, tri-, quad-, hexa-, octo-core chips to ones with tens or even hundreds of cores.

In contrast to multi-core systems, the term multi-CPU refers to multiple physically separate processing-units (which often contain special circuitry to cilitate communication between each other).

Chuck Moore […] suggested computers should be more like cellphones, using a variety of specialty cores to run modular software scheduled by a high-level applications programming intece. […] Atsushi Hasegawa, a senior chief engineer at Renesas, generally agreed. He suggested the cellphones use of many specialty cores working in concert is a good model for future multi-core designs.

An dual-core processor.A multi-core processor is a single computing component with two or more independent actual central processing units (called cores), which are the units that read and execute program instructions.

Multi-core processing has also affected the ability of modern computational software development. Developers programming in newer languages might find that their modern languages do not support multi-core functionality. This then requires the use of numerical libraries to access code written in languages like C and Fortran, which perform math computations ster than newer languages like C. Intels MKL and AMDs ACML are written in these native languages and take advantage of multi-core processing. Balancing the application workload across processors can be problematic, especially if they have different performance characteristics. There are different conceptual models to deal with the problem, for example using a coordination language and program building blocks (programming libraries and/or higher order functions). Each block can have a different native implementation for each processor type. Users simply program using these abstractions and an intelligent compiler chooses the best implementation based on the context.

In order to continue delivering regular performance improvements for general-purpose processors, manucturers such as Intel and AMD have turned to multi-core designs, sacrificing lower manucturing-costs for higher performance in some applications and systems. Multi-core architectures are being developed, but so are the alternatives. An especially strong contender for established markets is the further integration of peripheral functions into the chip.

Multi-core chips also allow higher performance at lower energy. This can be a big ctor in mobile devices that operate on batteries. Since each and every core in multi-core is generally more energy-efficient, the chip becomes more efficient than having a single large monolithic core. This allows higher performance with less energy. The challenge of writing parallel code clearly offsets this benefit.

Embedded computing operates in an area of processor technology distinct from that of mainstream PCs. The same technological drivers towards multi-core apply here too. Indeed, in many cases the application is a natural fit for multi-core technologies, if the task can easily be partitioned between the different processors.

the traditional Network Processors that were based on proprietary micro- or pico-code.

Multi-core processors are widely used across many application domains including general-purpose, embedded, network, digital signal processing (DSP), and graphics.

In addition, multi-core chips mixed with simultaneous multithreading, memory-on-chip, and special-purpose heterogeneous cores promise further performance and efficiency gains, especially in processing , recognition and networking applications. There is also a trend of improving energy-efficiency by focusing on performance-per-watt with advanced fine-grain or ultra fine-grain power management and dynamic voltage and frequency scaling (i.e. laptop computers and portable media players).

Microsoft has said they would treat a socket as a single processor.

For general-purpose processors, much of the motivation for multi-core processors comes from greatly diminished gains in processor performance from increasing the operating frequency. This is due to three primary ctors:

Manucturers typically integrate the cores onto a single (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.

Core i3, Core i5 and Core i7, a mily of multi-core processors, the successor of the Core 2 Duo and the Core 2 Quad.

Some systems use many soft microprocessor cores placed on a single FPGA. Each core can be considered a semiconductor intellectual property core as well as a CPU core

The terms many-core and massively multi-core are sometimes used to describe multi-core architectures with an especially high number of cores (tens or hundreds).

In the third stage, development moves from the abstract toward the concrete. Developers revisit decisions made in the partitioning and communication phases with a view to obtaining an algorithm that will execute efficiently on some class of parallel computer. In particular, developers consider whether it is useful to combine, or agglomerate, tasks identified by the partitioning phase, so as to provide a smaller number of tasks, each of greater size. They also determine whether it is worthwhile to replicate data and/or computationCore.

The composition and balance of the cores in multi-core architecture show great variety. Some architectures use one core design repeated consistently (homogeneous), while others use a mixture of different cores, each optimized for a different, heterogeneous role.

It would be possible for an application that used two CPUs to end up running ster on one dual-core if communication between the CPUs was the limiting ctor, which would count as more than 100% improvement.

Utilizing a proven processing-core design without architectural changes reduces design risk significantly.

The partitioning stage of a design is intended to expose opportunities for parallel execution. Hence, the focus is on defining a large number of small tasks in order to yield what is termed a fine-grained decomposition of a problem.

The tasks generated by a partition are intended to execute concurrently but cannot, in general, execute independently. The computation to be performed in one task will typically require data associated with another task. Data must then be transferred between tasks so as to allow computation to proceed. This information flow is specified in the communication phase of a design.

As the rate of clock speed improvements slowed, increased use of parallel computing in the form of multi-core processors has been pursued to improve overall processing performance. Multiple cores were used on the same CPU chip, which could then lead to better sales of CPU chips with two or more cores. Intel has produced a 48-core processor for research in cloud computing; each core has an X86 architecture.

The article CPU designers debate multi-core future by Rick Merritt, EE Times 2008,

An outdated version of an anti-virus application may create a new thread for a scan process, while its GUI thread waits for commands from the user (e.g. cancel the scan). In such cases, a multi-core architecture is of little benefit for the application itself due to the single thread doing all heavy lifting and the inability to balance the work evenly across multiple cores. Programming truly multithreaded code often requires complex co-ordination of threads and can easily introduce subtle and difficult-to-find bugs due to the interweaving of processing on data shared between threads (thread-safety). Consequently, such code is much more difficult to debug than single-threaded code when it breaks. There has been a perceived lack of motivation for writing consumer-level threaded applications because of the relative rarity of consumer-level demand for maximum use of computer hardware. Although threaded applications incur little additional performance penalty on single-processor machines, the extra overhead of development has been difficult to justify due to the preponderance of single-processor machines. Also, serial tasks like decoding the entropy encoding algorithms used in video codecs are impossible to parallelize because each result generated is used to help create the next result of the entropy decoding algorithm.

Canon Digital Cameras

Please tell us about the quality of the product. This is a top-notch, almost leica quality digital rangefinder-esque camera.

5.0I have had a lot of digital cameras over the years but they are now on the shelf collecting dust. This camera has many features that only high end cameras have. An example is the capability of taking 10 photos in a second with one press of the shutter release. Thats a nice feature when taking photos of animals (or children) when they are constantly moving. You pick the best photo out of the ten and delete the rest. Another nice feature that I use a lot is the ability to take a photo of a person inside a house with a big bright window behind them (back lighting). Most cameras will darken the ce so much that it wont show up in the final photo. This camera takes three to five photos at one click of the shutter release, averages the lighting and then where there is a dark ce it will lighten it up to match the rest of the picture. It works like magic. Sony has a big advantage of features, quality and simplicity in use that other camera manucturers dont have. I recommend…

Was the product free of any manucturer defects? Completely Free! be sure to upgrade to the latest firmware!

4.0Great for little preteens and teens, has a lot of fun photo tools built into the camera. It allows for them to take self portraits, and also take pictures of their little siblings with the funny cartoon displayed in front of the camera. I would not recommend this for older children or adults, as its just too hard to use for sharing Cameras,new york escort youll want a real keyboard for entering in data. Canon Digital CamerasBut for kids with their enormous patience it is fine.

5.0Overstock quickly shipped this camera to me after an order verification which is totally understandable! This camera did not come with a lens, however, I am using it with old lenses Ive collected in the past such as m42s and M mount lenses. There are plenty of adapters that you can purchase to use on this amazing camera! The menu does take some getting used to but eventually becomes second nature and focusing is a total breeze! If youre looking for a pro-sumer digital camera and want something a little above the rest, get this now! Thank you, Overstock!

Was the product free of any manucturer defects? no, it stopped working and I just order it on May 28, 2013.
