Nvidia CUDA Toolkit 3.2 - more Fermi optimizations

The latest Nvidia "Fermi" GPUs (Graphical Processing Units) are available in a wide range of powerful new Nvidia Graphics Cards. If you have been waiting for a good reason to upgrade your graphics card, Nvidia has certainly provided some great reasons to upgrade with their latest CUDA-capable Nvidia cards that are just amazing!

For over a year, I was patiently waiting for the new Fermi architecture to hit the shelves so that I could get the latest CUDA parallel processing power at an incredible performance-per-watt and price-per-performance level. I have been looking forward to writing some parallel-processing-optimized code, and these cards were exactly what I needed. I ended up buying a Quadro 600 to start with, since it has 96 processing cores and only uses 40 watts of power! So far, I have been quite impressed by this card's abilities, quiet operation, and price (well under $200). I can now perform "real time" graphical operations that were impossible before. It is like having a 5 or 10 year old multi-million-dollar supercomputer on my desktop for under $200.

Personal supercomputing for the masses!
Nvidia (NASDAQ:NVDA) has moved to a modern 40nm architecture for these new GPUs, which has allowed them to be much more power-efficient while cranking out tons of graphics horsepower for gaming and/or professional applications that make use of their stream-processors (aka, "CUDA cores") on the graphics card for high-performance computing (HPC) via massively-parallel-processed algorithms.

CUDA is NVIDIA’s parallel computing architecture that enables dramatic increases in computing performance by harnessing the power of the GPU (graphics processing unit) for applications including image and video processing, computational biology and chemistry, fluid dynamics simulation, CT image reconstruction, seismic analysis, ray tracing, and much more.

Get an NVidia Fermi-based Graphics Card
First, get hold of a new Fermi-based Nvidia CUDA Graphics card  to develop and run your new CUDA applications on.

Now you can start putting some new CUDA abilities to work using the latest Nvidia CUDA Toolkit 3.2 release that has some features specific to the new Fermi cards and architecture that you may want to check into...

    Financial Opportunities :
    Nvidia (NASDAQ:NVDA) stock?

    Since this blog also focuses on stock-market and investing opportunities, I have to point out that in my August 13th, 2010 blog entry about Nvidia Toolkit 3.1 news, I contemplated whether the new Nvidia Fermi cards were going to drive substantial sales/revenue-gains and associated profit-gains for Nvidia corporation.

    When I wrote that blog entry in August, Nvidia stock was $9.39, and today it is $14.77 as I write this article. If you jumped in on this one, you have already made 57% in a mere 4 months! (update: May-2011; NVDA at $19.00+) The current trend-lines on the stock look good, as it is staying ahead of its moving-average trend-lines on a technical basis, so it may well have some decent upside remaining. Plus, we are rather early in the Fermi-chip-based GPU series from Nvidia. 50+% return on your NVDA stock may have you wanting to take some profits. The choice is yours... this stock has a long-history of being rather volatile, and it will likely have some up/down cycles during its future. I plan to maintain at least some of my position in NVDA as I still think they have the technology to beat when it comes to GPU-computing and supercomputing. Intel's "Sandy Bridge" products coming out in Q1-2011 may have a slight impact on Nvidia (since the new Intel CPUs will include an integrated and allegedly rather capable GPU onboard, which will perhaps suffice for mainstream users).

    WHO is going to use these cards?
    The thing that I see happening with these discrete graphics cards like the Fermi-based CUDA-capable Nvidia cards is simple: if you are a business and you want to compete, you best learn how to leverage the power of these cards. Period.

    Wall Street already knows this (and, I do not mean in the price of NVDA stock),... they are using this technology to perform lightning-fast calculations for algorithmic trading, options pricing, and much more. ANY application that can be significantly enhanced (i.e., made faster and more robust) through parallel processing will be made so by the companies that are leading in any field. They WILL use these GPUs from Nvidia to accomplish that feat.

    I am not investing in Nvidia for the fact that home "gamers" and the like enjoy their super-potent "GeForce" cards... I am in this because businesses are going to use TONS of these cards/GPUs in their "desktop supercomputers" for analyzing all sorts of things throughout their domain. Mark my words: companies that miss this opportunity (to leverage CUDA and parallel processing) are going to find themselves looking like Blockbuster as compared to Netflix now.

    The margins on Nvidia's "Quadro" business-oriented line of cards is likely higher than that on the consumer "GeForce" line, and certainly their Tesla dedicated supercomputing-desktop devices are going to be money makers as businesses figure out how to use these (i.e., find talented developers to help them write some seriously cool parallel-enabled algorithms and applications software). This may take a while yet, but I would say that within 3-5 years, MOST serious business applications will make some use of CUDA and/or GPUs for heavy analytical processing.

    Bottom line: NVIDIA HAS SOME AWESOME GRAPHICS CARDS TO CONSIDER, and some nicely updated tools to go with them!
