Tilera Launches 64-Core Embedded Processor

MIT Spin-out creates 64-core processor based on "mesh" architecture

Tilera Corporation, 2004 MIT startup founded on proof-of-concept mesh-based computing today launched the TILE64 processor. TILE64 is the first in a family of Tile Processor chips based on am architecture that can scale to hundreds and even thousands of cores.

However, don't get too excited while dreaming of 64-core gaming. Tilera claims the TILE64 has potential uses in video processing and network applications, but the processor is designed more as 64 systems on a single chip, rather than a 64-core general purpose GPU.

"This is the first significant new development in chip architecture in a decade," said Tilera President and CEO, Devesh Garg. "We developed this new architecture because existing multicore technologies simply cannot scale beyond a handful of cores. Moreover, customers have repeatedly indicated that the current multicore software tools are very primitive because they are based on single-processor-core models. We're introducing a revolutionary hardware and software platform that has solved the fundamental challenges associated with multicore scalability."

Tilera's new architecture eliminates the on-chip bus interconnect by placing a communications switch on each processor core and arranging them in a grid fashion on the chip, which the company calls iMesh -- intelligent Mesh.

Instead of a dedicated socket interface, the TILE64 daughterboard plugs into standard PCIe. A host operating system -- Linux or Windows -- recognizes the daughterboard as a new device instead of an extra 64 CPUs.

Each of the tiles is a full-featured, general-purpose processor that includes L1 and L2 caches, as well as a distributed L3 cache. Each core is also capable of running its own operating system, such as Linux. The cores can then interact with the iMesh network, which provides extremely low-latency, high bandwidth communications between the cores, memory and the I/O.

Intel's Teraflops Research Chip carries a striking resemblence to TILE64. Indeed, Tilera and Intel even carry the same terminology to describe the tiles and their functionality. In theory, both chips behave almost identically with regard to mesh computing -- one tile or several tiles can be confgured to act in parallel.

In order to minimize total system power, cost and footprint, the TILE64 processor integrates four DDR2 memory controllers and a complete array of high speed I/O interfaces; including two 10 Gbps XAUI, two 10 Gbps PCIe, two 1 Gbps Ethernet RGMII and a programmable flexible I/O interface to support interfaces such as compact flash and disk drives.

Each core consumes approximately 170 to 300 milliwatts. While each core does not reside on a separate power plane individual cores can be set into deep sleep states. However even with this aggressive sleep state management, the process is still fabricated entirely on TSMC's aging (and relatively inefficient) 90nm node; the company has not announced plans to shrink this process technology.

Intel's Teraflops Research Chip boasts nearly two teraFLOPs of processing power on a single 80-core processor, TILE64 musters about a tenth of that. However, aside from the fact that Tilera's CPU is available today, the focus for TILE64 is high performance-per-watt, as evidenced by its sub-20 watt peak-load envelope.

The processor is ideally suited for high performance embedded system markets, such as switches, security appliances and high-definition video applications. Tilera claims the chip will be available today in 600MHz to 900MHz variants, though corporate documentation (PDF) suggests 1GHz models exist but are not commercially available. Production pricing for the TILE64-family starts at $435 in bulk quantities.

Tilera's roadmap also includes plans for a 36-core and a 120-core device.

NVIDIA GeForce 9800 GTX and GTS already in November?

The rumor kitchen around NVIDIAs next GeForce generation runs again on full speed. Different sources assume the new generation will come in November on us. Over leaky placing the first Specs is to have come to the daylight.

If one had assumed that first, which becomes the G92 rather a Midrange map, one goes now nevertheless rather from a High ends to model, thus to a GeForce 9800 out. With the GeForce 9800 the GeForce 8800 will already again retired have and it comes a further technology step to us.

To the unconfirmed data from the Leak sources according to the G92 is introduced in November 2007. The new GPU is over a billion (1000 million.) Transistors order. To the comparison, in the G80 there 681 millions.

The G92 will possess 9800 GTX version into the GeForce the following specifications:

- 65nm process technology RK TSMC.
- Over one trillion of transistor.
- Second generation Unified Shader Architecture.
- doubles precsion support (FP64).
- GPGPU native.
- Over one TeraFLOPS OF of shader processings power.
- MADD+ADD configuration for the more shader untis (2+1 FLOPS FLOPS by ALU)
- Fully Scalar Design.
- 512-bit MEMORY interface.
- 1024MB GDDR4 graphics MEMORY.
- DirectX 10,1 support.
- OpenGL 3,0 support.
- OD RAM for the "FREE 4xAA".
- Built in audio chip (HDMI).
- Built in tesselation unit (into the graphics core)
- Improved AA and AF quality level

Also the prices for the maps are obviously already more or less well-known. So the GTX version of the GeForce 9800 is to lie between 549 and 649 USD and the GTS version between 399 and 449 USD.

Microsoft Reminds : No Vista SP 1 This Year

Microsoft Reminds that this year will no Vista SP1.
______________________________________________________________
"There will be a Windows Vista service pack and our current expectation is that a beta will be made available sometime this year. Service packs are part of the traditional software lifecycle -- they’re something we do for all Microsoft products as part of our commitment to continuous improvement, and providing early test builds is a standard practice that helps us incorporate customer feedback and improve the overall quality of the product," Microsoft said in a statement.

Although it wouldn't explicitly said so, Microsoft's plans put a final release of Vista SP1 -- what customers are actually waiting for, not a beta -- sometime next year. And in the meantime, the company is busy telling customers they shouldn't wait at all.

"Since Windows Vista launched, we have continued working with partners to improve overall device coverage and application compatibility. There are now more than 2.1 million supported devices and more than 2,000 logoed applications for Windows Vista. We think customers will have a great experience using Windows Vista today," Microsoft added.

Viewing File Extension Name

Sometime, you need to see your files extension. But many/almost all files are not viewing the extension anymore after it finds a program to open it. Maybe you knew it a long time ago, but I will tell you who doesn't know it yet. There only one setting needed to view the extension.

Follow these steps:
1) Open a folder or "My Computer"
2) Click "Tools" at menu bar (If I’m right), select "Folder Options"
Or
1) "Start Menu", "Control Panel"
2) "Switch to Classic view (For Win XP) at the left side", select “Folder Options"
3) Select "View" tab
4) At the "advanced Settings" un-check "Hide extension known file types"
5) OK

Now see your file names! There are the extension names.

NOTE: But BE CAREFUL, because now you can change the extension.
But if you changed/deleted the extension to other extension, IT CAN BE UNUSABLE!!

Removing Icon Label / Name

TIPS - If you have too many icons on your desktop, you memorized your icon(s) name, and it's make your desktop look messy. Then, you want to make it neater you can try one of my tips that I get from CHIP mags. This tips can makes your icon be no name, if before previously you try to rename your file with just a "space", then “enter/return" it's useless, because it will back to the previous name.

Follow these steps:
1) Select one of icon on your desktop
2) Right-click, Rename or "F2"
3) Press & Hold "alt"
4) Type "0160" at your Numeric Pad
5) Release "alt"
6) "Enter/Return"

Your icon name will be blank and your desktop will look neater.
Not only at desktop, can it also be used in folders. Folder name will works too.

NOTE: If you trying this on notebook it will be more difficult, because notebook have no numpad. But some notebook does, it’s be one with your keyboard. Like mine notebook Toshiba 2450, the numpad can be activated with "Fn+F11".
Then my numpad activated with:
"m=0, j=1, k=2, l=3, u=4, i=5, o=6, 7=7, 8=8, 9=9". "=" mean become.
You can check your notebook "fn" function at the manual or ask to your notebook Customer Service.

You can copy it to other by copying the "space" that we made from these steps, and then paste it to other files/folder.
