NVIDIA Updates CUDA: Major Release for Science Research

Subject: General Tech, Graphics Cards | January 28, 2012 - 11:53 PM |
Tagged: nvidia, gpgpu, CUDA

NVIDIA has traditionally been very interested in acquiring room in the high-performance computing for scientific research market. For a lot of functions, having a fast and highly parallel processor saves time and money compared to having a traditional computer crunch away or having to book time with one of the world’s relatively few supercomputers. Despite the raw performance of a GPU, adequate development tools are required to bring the simulation or calculation into a functional program to execute on said GPU. NVIDIA is said to have had a strong lead with their CUDA platform for quite some time; that lead will likely continue with releases the size of this one.

What does a tuned up GPU purr like? Cuda cuda cuda cuda cuda.

The most recent release, CUDA 4.1, has three main features:

  • A visual profiler to point out common mistakes and optimizations and to provide instructions which detail how to alter your code to increase your performance
  • A new compiler which is based on the LLVM infrastructure, making good on their promise to open the CUDA platform to other architectures -- both software and hardware
  • New image and signal processing functions for their NVIDIA Performance Primitives (NPP) library, relieving developers the need to create their own versions or license a proprietary library

The three features, as NVIDIA describes them in their press release, are listed below.

New Visual Profiler - Easiest path to performance optimization
The new Visual Profiler makes it easy for developers at all experience levels to optimize their code for maximum performance. Featuring automated performance analysis and an expert guidance system that delivers step-by-step optimization suggestions, the Visual Profiler identifies application performance bottlenecks and recommends actions, with links to the optimization guides. Using the new Visual Profiler, performance bottlenecks are easily identified and actionable.

LLVM Compiler - Instant 10 percent increase in application performance
LLVM is a widely-used open-source compiler infrastructure featuring a modular design that makes it easy to add support for new programming languages and processor architectures. Using the new LLVM-based CUDA compiler, developers can achieve up to 10 percent additional performance gains on existing GPU-accelerated applications with a simple recompile. In addition, LLVM's modular design allows third-party software tool developers to provide a custom LLVM solution for non-NVIDIA processor architectures, enabling CUDA applications to run across NVIDIA GPUs, as well as those from other vendors.

New Image, Signal Processing Library Functions - "Drop-in" Acceleration with NPP Library
NVIDIA has doubled the size of its NPP library, with the addition of hundreds of new image and signal processing functions. This enables virtually any developer using image or signal processing algorithms to easily gain the benefit of GPU acceleration, with the simple addition of library calls into their application. The updated NPP library can be used for a wide variety of image and signal processing algorithms, ranging from basic filtering to advanced workflows.

Guess what? Overclocked.

The NVIDIA GTX 580 GPU, based on the GF110 Fermi architecture, is old but it isn't forgotten.  Released in November of 2010, NVIDIA had held the single GPU performance grown for more than a year before it was usurped by AMD and the Radeon HD 7970 just this month.  Still, the GTX 580 is a solid high-end enthusiast graphics card that has wide spread availability and custom designed, overclocked models from numerous vendors making it a viable option.

Gigabyte sent us this overclocked and custom cooled model quite a while ago but we had simply fallen behind with other reviews until just after CES.  In today's market the card has a bit of a different role to fill - it surely won't be able to pass up the new AMD Radeon HD 7970 but can it fight the good fight and keep NVIDIA's current lineup of GPUs more competitive until Kepler finally shows himself?

The Gigabyte GTX 580 1.5GB Super Overclock Card

With the age of the GTX 580 designs, Gigabyte had plenty of time to perfect their PCB and cooler design.  This model, the Super Overclock (GV-N580SO-15I), comes in well ahead of the standard reference speeds of the GTX 580 but sticks to the same 1.5 GB frame buffer.

The clock speed is set at 855 MHz core and 1025 MHz memory, compared to the 772 MHz core speed and 1002 MHz clock rate of the reference design.  That is a very healthy 10% clock rate difference that should equate to nearly that big of a gap in gaming performance where the GPU is the real bottleneck.

FBI Arrests Seven People for Insider Trading of Dell and Nvidia Stock

Subject: General Tech | January 19, 2012 - 03:40 PM |
Tagged: dell, nvidia, insider trading, tech, Law, ethics

There is an important distinction between working within the confines of the law to make the most profit possible and going outside those lines to make a profit while hoping you don't get caught. To drive that point home, the FBI has stated "what distinguishes you from the dozens who have been charged is not that you haven’t been caught; it’s that you haven’t been caught yet." Assistant Director in Charge Janice K. Fedarcyk wrote that when referring to a recent bust of seven individuals accused of insider trading of Dell and Nvidia stock. The arrests, made as part of Operation Perfect Hedge, include seven men who are connected by "friendship or business association."

funny-pictures-fbi-cat-installs-surveillance-while-you-are-away.jpg

Thanks to three of the seven men cooperating with the FBI, we know that the men used information about Dell and Nvidia's quarterly earnings prior to any public release of such earnings documents to purchase stock to resell after positive earning documents caused the stock value to increase or to short their stock to avoid losses that would be incurred by lower than expected quarterly earnings causing the stock price to drop. On the Dell side of things, two employees in the know provided quarterly earnings numbers to various hedge funds. The first employee, Sandy Goyal, is charged with providing a hedge fund with Q1 earning results for 2008 in exchange for $175,000. The hedge fund then used that insider information to make $3.8 million dollars. Another (former) Dell employee, Jesse Tortora furnished three hedge funds with quarterly earnings numbers who each then made $4 million on Q1 information and $53 million on the Q2 information, $1 million in profit, and the final Hedge fund avoided #78,000 in losses by selling stock before the inevitable price drop thanks to knowing the negative earning numbers before hand.

Finally, Danny kuo knew someone who worked at Nvidia and provided information to the other members of the insider trading group.

Let this be a lesson to those business folks that slept through ethics classes, stay away from insider trading, especially when you are paid for the information as you are just asking to get caught. (Cue the "Cops" theme song).  Normally we don't cover this kind of news; however, I thought it applicable since it involves Dell and Nvidia.  Also, speaking of quarterly earnings, Josh will have all the details from today's Intel Earnings Call up soon.

Are AMD's Southern Islands about to be swamped by a Kepler tidal wave?

Subject: Graphics Cards | January 19, 2012 - 12:06 PM |
Tagged: nvidia, kepler, GK104, amd

AMD had better hope that SemiAccurate lives up to their tongue in cheek name because according to their sources NVIDIA's new Kepler GPU line is going to better AMD at everything.  The variety of negative rumours about Kepler are contradicted by the news that the A2 silicon has arrived, trouble free, at NVIDIA's door step so the early arrival of Kepler in May now seems reasonable. 

From the limited description we have it seems that NVIDIA's Achilles Heel, multi-monitor support on a single card is no longer a problem as there are two DVI plugs, a single HDMI, and a DisplayPort connector present.  With all of those plugs it seems obvious the card is designed to handle NVIDIA Surround all by its lonesome.  From the GDDR5 count the cards bandwidth of 256 bits and total memory size of 2GB is lesser than AMD's 384-bit, 3GB card but from the description at SemiAccurate that is not going to be enough to save AMD's biscuit.

Ex-cellent

"The short story is that Nvidia (NASDAQ:NVDA) will win this round on just about every metric, some more than others. Look for late March or early April availability, with volumes being the major concern at first. GK104 cards seen by SemiAccurate all look very polished and complete, far from rough prototypes or “Puppies“. A2 silicon is now back from TSMC, and that will likely be the production stepping barring any last second hitches. Currently, there aren’t any."

Nvidia May Launch GK104 "Kepler" GPUs Ahead Of Schedule

Subject: Graphics Cards | January 17, 2012 - 03:08 AM |
Tagged: nvidia, kepler, gtx 680, gf104

AMD's latest graphics cards are already hitting the street, but Nvidia's high end GPUs are nowhere to be seen. Late last year, we heard rumors that Nvidia's GK104 "Kepler" graphics cards may be delayed to an early summer or late spring launch. If the latest rumors reported by Maximum PC hold true; however, Nvidia's Kepler cards' release may be leaning more towards a late spring launch instead of an early summer window.

Nvidia-GTX-680.jpg

They report that sources from Chinese website ChipHell.com have indicated that Nvidia's new high end GTX 680 graphics cards may be released as soon as February 2012. This is a relatively big push forwards compared to the previously rumored March or April launch window, and is likely being accelerated in response to AMD's successful launch of their GCN (Graphics Core Next) based Radeon 7970 graphics cards.  Although we do not know much about the upcoming cards, the general consensus is that the GTX 680 cards will have 2 GB of video memory on a 256-bit bus.  Further, the Kepler cards' core will run at 780 MHz, and the GK104 cards will have TDP (thermal design power) ratings of 225 Watts.  

Whether the company will have actual hardware to sell or if it will be more of a "paper launch" remains to be seen. If I had to venture a guess, the cards will likely see limited availability in a late February launch but will not be around in significant quantities until later this year. With the delays caused by manufacturing the 28nm Kepler cards over at TSMC, the company is not likely to have all that big of a stockpile on hand.

NVIDIA Shows Tegra DirectTouch and $249 ASUS Tegra 3 Tablet

Subject: Mobile | January 9, 2012 - 09:26 PM |
Tagged: tegra 3, tablet, nvidia, mobile, CES

nvidiaces1.jpg

Much of today’s NVIDIA CES conference focused on small milestones, including the implementation of apps and new app features. The company showed multiplayer LAN gaming, easy access to your PC’s desktop via an app called Splashtop, and highlighted the NVIDIA Tegra Zone curated gaming app store. All of this is interesting – but not new 

nvidiaces2.jpg

There were a couple tricks up the green team’s sleeves, however. One is a new feature for use with Tegra 3 processors called DirectTouch. This allows the fifth low-power hardware core on Tegra 3 to act as a touchscreen controller. Usually an independent piece of hardware performs this task, and it’s much slower than the low-power Tegra 3 core. As a result, touchscreen sampling speed can be increased by up to three times – allegedly resulting in a smoother touch experience. We’ve yet to see how it pans out in execution, but the idea is promising.

Another interesting piece of tech that will be made available by Tegra 3 is called PRISM. It attempts to compensate for the image fidelity reduction that occurs when a mobile device is used with its display at a low brightness setting.

Availability for both of these features is not yet clear. 

The remaining big announcements came via ASUS. First was the decision to release Ice Cream Sandwich on the Prime today, January 9th.  As of the time of this writing it should be available for download via the built-in OS update functionality of Honeycomb. 

nvidiaces3.jpg

Second was an ASUS 7” tablet featuring ICS, Tegra 3 and a low $249 price point. Oddly, the tablet was not named at the conference, but it appears to be the ASUS Eee Pad MeMO 370T. To clarify earlier information, the MeMO 171 is the version with a Qualcomm processor, stylus and cellular networking support, while the MeMO 370T offers Tegra 3.

The reasons for being excited about a $249 Tegra 3 tablet are obvious. That’s the same as a Nook Color and not much more than a Kindle Fire – both of which run far older versions of Android (Gingerbread) and use older dual-core OMAP processors.

Last, and unfortunately least, was a demonstration of Windows 8 on a Tegra 3 reference platform. While Microsoft’s new OS looks very sleek on the device, nothing new was announced, nor were new features introduced. It seems we’ll have to wait awhile longer to see products pairing Tegra 3 and Windows 8.
