NVIDIA today announced the latest version of the NVIDIA CUDA Toolkit for developing parallel applications using NVIDIA GPUs. The NVIDIA CUDA 4.0 Toolkit was designed to make parallel programming easier, and enable more developers to port their applications to GPUs. This has resulted in three main features:

• NVIDIA GPUDirect 2.0 Technology -- Offers support for peer-to-peer communication among GPUs within a single server or workstation. This enables easier and faster multi-GPU programming and application performance.
• Unified Virtual Addressing (UVA) -- Provides a single merged-memory address space for the main system memory and the GPU memories, enabling quicker and easier parallel programming.
• Thrust C++ Template Performance Primitives Libraries -- Provides a collection of powerful open source C++ parallel algorithms and data structures that ease programming for C++ developers. With Thrust, routines such as parallel sorting are 5X to 100X faster than with Standard Template Library (STL) and Threading Building Blocks (TBB).

After a well-received launch of the Fusion "Zacate" accelerated processing unit (APU) for nettops and entry-level PCs, AMD's higher-performance APU, codenamed "Llano", is just around the corner. Llano is intended for use on mainstream desktops, business PCs, and all-in-one PCs, it is better geared for higher-resolution, visually-intensive computing. Its competitors include Intel's Core i3 and Core i5 dual-core processors. AMD is backing up this launch with a new multi-GPU technology which is both similar and different from Hybrid CrossFireX. The similar part is that the GPU embedded in the Fusion chip will work in tandem with a discrete AMD Radeon graphics card, the difference is that it can work with any HD 6000 series graphics card, and multiply the available display connectivity.

The Fusion Llano APU will be part of AMD's Lynx mainstream desktop platform. The Llano APU embeds two x86-64 processing cores that feature the latest SIMD extensions, a DirectX 11 compliant GPU, a dual-channel DDR3 memory controller, a PCI-Express 2.0 hub, and an interconnect to the Hudson M1 chipset. The APU gives out a PCI-Express 2.0 x16 port, which is configurable using external switching. AMD also ran its own internal tests to show the performance advantage the new multi-GPU technology will give. AMD's Lynx mainstream desktop platform is expected to launch a little later this year.

TUL Corporation, a manufacturer under the leading graphics card brand PowerColor, today introduces a completely new product lineup for computer enthusiasts: the PowerColor Power Supply Unit (PSU) series. The series includes Extreme 1000W, 850W and Gaming 600W, 500W power supplies, targeting high-end to upper mid-range segments.

The PowerColor Extreme and Gaming series features 80 Plus Bronze and 80 Plus rated separately, offering more than 85% power efficiency in Extreme series and 80% in Gaming series, decreasing wasted power while increasing power transmission.

The MSI Big Bang-XPower is making its much anticipated debut in April of this year. MSI, a leading mainboard and graphics card maker, with over 23 years of R&D and manufacturing experience, has made its name catering to performance-hungry gamers. The Big Bang-XPower is another exceptional mainboard from the Big Bang series with astonishing performance and reliability. MSI is confident that the Big Bang-XPower will again be selling like hotcakes to users worldwide.

MSI's Big Bang-XPower mainboard is built with Military Class components that includes a Hi-c CAP (highly-conductive polymerized capacitor), Solid Cap (solid capacitor), and Icy Choke for longer lifespan, better thermal reliability, and stability. The Hi-c CAP has excellent physical properties of thermally stable, reliable, performs under stress, and lasts 8X longer than traditional solid capacitors. Icy Choke is a new generation ferrite choke that features low temperature and longer lifespan. Military Class Solid CAP lasts longer than traditional capacitors, up to 10 years of lifespan. All these Military Class components add up to a stable and long lasting mainboard that will keep running even under high stress conditions.

ASUS today announced the launch of the new ASUS P7F7-E WS SuperComputer motherboard which maximizes transmission speeds by integrating the industry's latest I/O technologies such as USB 3.0, SATA 6G storage interface, and IEEE 1394b FireWire standard. Additionally, the ASUS P7F7-E WS SuperComputer is equipped with the LGA1156 socket and the latest Intel 3450 chipset with onboard graphics. For extreme gaming enjoyment, up to four ATI CrossFireX cards or 3-way/2-way NVIDIA SLI cards can be accommodated to generate smoother and sharper visuals. It also leverages NVIDIA CUDA parallel computing architecture to support up to four NVIDIA Tesla cards with Clarkdale Processors for intensive high-performance computing.

The ASUS P7F7-E WS SuperComputer is the best choice for providing comprehensive I/O support. It includes USB 3.0 ports-the latest connectivity standard with 4.8Gb/s speeds-to support next-generation components and peripherals. USB 3.0 transfers data ten times faster and is backward compatible with USB 2.0 components. Additionally, the ASUS P7F7-E WS SuperComputer includes Serial ATA (SATA) 6Gb/s storage interfaces for 6.0Gbps data throughput, thus enhancing scalability, accelerating data retrieval, and doubling the bandwidth of current bus systems. To support FireWire-enabled digital video recorders and computers, the ASUS P7F7-E WS SuperComputer also includes two IEEE 1394b ports supporting up to 800 Mb/s speeds-doubling the previous IEEE 1394a speeds.

AMD released the latest version of its ATI Catalyst software suite. Version 9.10 WHQL brings with it official support for the company's newest ATI Radeon HD 5800 series graphics processors, adds features that enhance usability under Windows 7, along with the usual list of bug fixes. The driver also adds support for Super Sample Anti-Aliasing, for Radeon HD 5800 GPUs. A complete list of changes can be read in the release notes document. The most important of them are listed below:

• ATI Catalyst 9.10 now includes full GPU support for the award winning ATI HD Radeon 5800 series GPUs.
• Provides support for a new Anti-Aliasing method on the ATI Radeon HD 5800 Series. Users can now experience the high level of anti-aliasing image quality using Super Sampling anti-aliasing while maintaining good performance levels
• Adds GPU acceleration for the Windows 7 Drag and Drop video converting application

EVGA and NVIDIA are readying a unique multi-GPU graphics accelerator this Halloween, slated for October 30. To celebrate its launch, the two have organized a launch party for 300 lucky participants who will go to the NVIDIA Plaza in Santa Clara, CA and witness the launch of the new GeForce product. The accelerator packs two GPUs: a G200b, and a G92b. That's right, a GeForce GTX 200 series GPU, with a GeForce GTS 250 GPU. This is perhaps the first graphics accelerator to pack two entirely different GPUs. How it works, however, is interesting: the G200b GPU handles graphics, while the G92b is dedicated to PhysX processing. The accelerator could have 896 MB of graphics memory, with 512 MB of dedicated memory for the PhysX GPU. You can sign up for the event here.

RivaTuner, the popular graphics card tweaking utility, was updated today towards version 2.20.

Microsoft has released yet another poor VGA performance patch. The Symptoms: in some scenarios, games and benchmarks perform more poorly than expected on a Windows Vista-based computer. This issue occurs when the games and the benchmarks use multiple display adapters in a Linked Display Adapter (LDA) configuration. A graphics processing unit (GPU) or part of a GPU link may incur a small scheduling latency on a new Direct Memory Access (DMA) packet. This is true if the DMA packet is submitted to the GPU that has previously run out of work and if another GPU in the linked configuration is very busy. In some scenarios, significant starvation of one or more GPUs in the linked configuration reduces the expected performance of an application. Dated December 3, 2007 more information for the hotfix including download link can be found here.
