وجود اين تاپيك هم به نظرم من لازم بود.

A Physics Processing Unit (PPU) is a dedicated microprocessor designed to handle the calculations of physics, especially in the physics engine of video games. Examples of calculations involving a PPU might include rigid body dynamics, soft body dynamics, collision detection, fluid dynamics, hair and clothing simulation, finite element analysis, and fracturing of objects. The idea is that specialized processors offload time consuming tasks from a computer's CPU

The first processor to be advertised as a PPU was called the PhysX chip, introduced by a fabless semiconductor company called AGEIA. Games wishing to take advantage of the PhysX PPU must use AGEIA's PhysX SDK, (formerly known as the NovodeX SDK).

The PhysX is currently available from 3 companies akin to the way graphics cards are manufactured. ASUS and BFG Technologies [1] are the primary manufacturers. PCs with the cards already installed are available from system builders such as Alienware, Dell, and Falcon Northwest.

Havox FX SDK is major competitor to the PhysX SDK. Used in more than 150 games, including major titles like Half-Life 2 and Dead Rising.[1]

To compete with the PhysX PPU, Havok FX will be able to take advantage of multi-GPU technology from ATI (CrossFire) and NVIDIA (SLI) using existing cards to accelerate certain physics calculations.[2]

Havok's solution divides the physics simulation into effect and gameplay physics, with effect physics being offloaded (if possible) to the GPU as Shader Model 3.0 instructions and gameplay physics being processed on the CPU as normal. The important distinction between the two are that effect physics do not affect gameplay (dust or small debris from an explosion, for example): the vast majority of physics operations are still performed in software. This approach differs significantly from the PhysX SDK, which moves all calculations to the PhysX card if it is present

Though not decicated PPUs, the latest GPU's from ATI and NVIDIA can be used as a PPU and other GPGPU (General-Purpose Computing on Graphics Processing Units) uses. The NVIDIA GeForce 8 Series supports a new GPU-based newtonian physics acceleration technology named Quantum Effects Technology - which will compete directly with the PhysX PPU hardware. NVIDIA uses provides a SDK Toolkit for what they call CUDA™ Compute Unified Device Architecture) technology that offers a low and high-level API to the GPU. ATI/AMD offers a similar SDK for their ATI GPUs and that SDK and technology is called CTM™ (Close To Metal™) with a hardware interface thin (thin hardware interface). AMD has also announced the AMD Stream Processor product line (combining a CPU and a GPU technology on one chip).

درسته که اینجا یه ?روم تخصصیه و بیشتر ا?راد هم متخصص ولی خب بعضیا هم مثل من متخصص نیستند که. چون از این تاپیکها و پستها تقریبا زیاد بوده و منم که اصلا حال خوندن اینهمه انگلیسی رو ندارم اینه که کلا بیخیال خوندن میشم.

Ageia outlines plans for PhysX
Author: Tim Smalley
Published: 22nd February 2007
Ageia's CEO claims that PhysX can accelerate calculations in scientific, engineering and financial applications.
Ageia's CEO claims that PhysX can accelerate calculations in scientific, engineering and financial applications.

CEO of Ageia, Manju Hedge, has revealed some of the company's plans for its PhysX physics processing unit in a recent interview published on Chile Hardware.

Hedge outlined that the company has been working with a number of game engines and triple-A titles based on them and he stated that there will be several titles with PPU support coming this year. The two titles that he made specific references to were Cell Factor: Revolution and Warmonger: Operation Downtown Destruction.

The first is probably a familiar name, since we looked at a demo version of the game in our PhysX coverage last year. The latter is an apocalyptic MMO FPS based on Unreal Engine 3 - an engine that is said to make heavy use of Ageia's PhysX technology.

He claims that current games use only a small portion of the PhysX's power, and games like Cell Factor: Revolution and Warmonger: Operation Downtown Destruction will put the PhysX card's power to better use.

Hedge also revealed that PhysX is able to accelerate other calculations in scientific, engineering and financial applications. He added that Ageia is working with partners so that PhysX can be used to accelerate their applications and went on to say that the company is also working on an SDK to make this process easier for its partners.

NVIDIA Corporation (Nasdaq: NVDA), the worldwide leader in programmable graphics processor technologies, today released a public beta of the NVIDIA® CUDA™ Software Developer Kit (SDK) and C-compiler for computing on NVIDIA graphics processing units (GPUs). GPU Computing with the CUDA SDK is a new approach to computing where hundreds of on-chip processors simultaneously communicate and cooperate to solve complex computing problems.

"The GPU is now a powerful, programmable processor that is ideally suited for computationally intensive applications such as seismic processing for oil and gas exploration, computing in bioscience, and financial modeling. With the recent introduction of CUDA technology, the parallel computing power of the GPU is now accessible to virtually any developer through standard C programming language," said Andy Keane, general manager of GPU Computing at NVIDIA.

NVIDIA's CUDA technology is available in GeForce® 8800 graphics and future NVIDIA Quadro® Professional Graphics solutions. Developers are invited to download the beta version of the CUDA Software Developers Kit (SDK) and C-compiler for Windows XP and Linux (RedHat Release 4 Update 3) from the NVIDIA Developer Web site at www.developer.nvidia.com. GPU Computing Forums for news, discussion and programming tips are also available at forums.nvidia.com.

Computing with NVIDIA CUDA technology transcends the limitations of traditional GPU stream computing by extending the function of the GPU to address a wide range of mathematically intensive problems. The breakthrough computing architecture in NVIDIA's latest generation G80 GPU is complemented by the CUDA C compiler – the first C compiler for the GPU. This complete development environment gives developers the tools they need to solve new problems in computation-intensive applications such as product design, data analysis, technical computing, and game physics.

اين ها براي پردازش ?يزيك هستند . ممكنه كارتهاي جديد اين كار رو انجام بدند . شركت nvidia va amd برنامه هائي هم دارند . ولي كارت ?يزيك تخصصش اين هست . پردازنده هيچ كمكي نميتونه انجام بده .

این که یه جورایی داره حر? من رو میزنه میگه پردازنده cell همین کار رو میکنه.
ولی به طور کلی ?کر کنم واحدهای پردازشی مختل? به سمت یکپارچه شدن حرکت میکنند.
