First 100 core processor is a reality
Tilera on Monday announced new general-purpose CPUs, including a 100-core chip, as it tries to make its way into the server market dominated by Intel and Advanced Micro Devices.
The two-year-old startup's Tile-GX series of chips are targeted at servers and appliances that execute Web-related functions such as indexing, Web search and video search, said Anant Agarwal, cofounder and chief technology officer of Tilera, which is based in San Jose, California. The chips have the attributes of a general-purpose CPU as they can run the Linux OS and other applications commonly used to serve Web data.
"You can run us as an adjunct to something else, though the intent is to be able to run it stand-alone," Agarwal said. The chips could serve as co-processors alongside x86 chips, or potentially replace the chips in appliances and servers.
Chip makers are continuously adding cores as a way to boost application performance. Most x86 server chips today come with either four or six cores, but Intel is set to release the Nehalem-EX chip, an x86 microprocessor with eight cores. AMD will shortly follow with a 12-core Opteron chip code-named Magny Cours. Graphics processors from companies like AMD and Nvidia include hundreds of cores to run high-performance applications, though the chips are making their way into PCs.
The Gx100 100-core chip will draw close to 55 watts of power at maximum performance, Agarwal said. The 16-core chip will draw as little as 5 watts of power.
Tilera's chips have an advantage in performance-per watt compared to x86 chips, but some will be skeptical as the chips are not yet established, said Will Strauss, principal analyst at Forward Concepts.
"I don't think an average person is going to run out to buy a computer with Tilera in it," Strauss said. Intel has the advantage of being an incumbent, and even if Tilera offered something comparable to Intel's chips, it would take years to catch up.
But to start, Tilera is focusing the chips on specific applications that can scale in performance across a large number of cores. It has ported certain Linux applications commonly used in servers, like the Apache Web server, MySQL database and Memcached caching software, to the Tilera architecture.

AMD LadyBug and Mecha DX11 demo download
AMD released the Mecha and LadyBug technology demo's yesterday on the developer website. Unfortunately it required a developer login in order to download them. Therefore we hosted them on our file-severs.
AMD Mecha DirectX 11 Demo
The Mecha demo shows the results of a new approach to rendering semi-transparent objects without pre-sorting, known as order-independent transparency (OIT). It is made possible by the ATI Radeon HD 5800 Series of graphics processors and the new features of Microsoft DirectX 11 technology. Blending is an order-dependent operation that requires sorting objects before rendering them. Atomic operations and append buffers make it possible to construct per-pixel fragment lists and sort them on the GPU. The results are a significant increase in speed and accuracy over those possible with traditional techniques.
AMD Ladybug DirectX 11 Demo
The Ladybug demo shows the results of a new approach to simulating lens-accurate depth-of-field effects based on real-world parameters of focal length and focus distance. This technique is made possible by the ATI Radeon HD 5800 Series of graphics processors and the Microsoft DirectX 11 and Direct Compute 11 technologies. Depth-of-field is used in feature films by cinematographers to subtly guide a viewer

Magnetic HDDs still cheapest in 2020
According to a new study, if HDDs continue to progress at their current pace, then in 2020 a two-disk, 2.5-inch disk drive will be capable of storing more than 14 TB and will cost about $40 (today, a typical 500 GB hard drive costs about $100). Although flash memories have also become popular - with advantages such as lower power consumption, faster read access time, and better mechanical reliability than HDDs - the cost per GB for flash memories is nearly 10 times that of HDDs. In addition, flash memory technology will reach technical limits that will prevent its continued scaling before 2020, keeping them from replacing HDDs.
In a study published in a recent issue of IEEE Transactions on Magnetics, Professor Mark Kryder and PhD student Chang Soo Kim of Carnegie Mellon University have investigated 13 up-and-coming NVM technologies to see whether one of them might outperform HDDs on a cost-per-TB basis in 2020. Their results showed that most technologies will probably not be competitive with HDDs or flash memories at that time, except for two potential candidates: phase change random access memory (PCRAM) and spin transfer torque random access memory (STTRAM).
As Kryder and Kim explained, PCRAM is based on the phase change properties of chalcogenide glass. With the application of heat, the glass can switch between two different states (amorphous and crystalline) to be used as a memory. With their small cell size and ability to store multiple bits per cell, PCRAMs have the potential to offer high densities and be cost-competitive with HDDs, but their biggest drawback is that they require somewhat higher power than most other technologies. PCRAMs are already beginning to be marketed by Numonyx Inc., an Intel-ST Microelectronics joint venture, and so are closer to practical realization than STTRAM.
STTRAM, which is similar to magnetic RAM, uses a spin polarized current to write data by reorienting the states of a magnetic tunnel junction between parallel and anti-parallel orientations. In their evaluation, Kryder and Kim found that STTRAMs appear to potentially offer superior power efficiency, among other advantages. If STTRAMs could be improved to store multiple bits per cell, the researchers predict that STTRAMs
