Too good to be true; bad coding versus GPGPU compute power

The skeptics were right to question the huge improvements seen when using GPGPUs in a system for heavy parallel computing tasks.  The cards do help a lot but the 100x improvements that have been reported by some companies and universities had more to do with poorly optimized CPU code than with the processing power of GPGPUs.  This news comes from someone who you might not expect to burst this particular bubble, Sumit Gupta is the GM of NVIDIA's Tesla team and he might be trying to mitigate any possible disappointment from future customers which have optimized CPU coding and won't see the huge improvements seen by academics and other current customers.  The Inquirer does point out a balancing benefit, it is obviously much easier to optimize code in CUDA, OpenCL and other GPGPU languages than it is to code for multicored CPUs.

"Both AMD and Nvidia have been using real-world code examples and projects to promote the performance of their respective GPGPU accelerators for years, but now it seems some of the eye popping figures including speed ups of 100x or 200x were not down to just the computing power of GPGPUs. Sumit Gupta, GM of Nvidia's Tesla business told The INQUIRER that such figures were generally down to starting with unoptimised CPU."

Intel CEO Paul Otellini Resigns in May 2013, Two Years Early

Subject: General Tech, Processors, Mobile | November 22, 2012 - 10:18 PM |
Tagged: Intel, CEO

Intel has not had any financial or directional problems nor have they experienced a revolving door in upper management, at least to my knowledge. Paul Otellini was expected to remain at the helm of the chip giant until he turned 65 at which point he would enjoy a wonderful retirement. He would have commanded the company for a full decade.

Intel recently announced that Otellini will leave the company and retire at 62.

Possibly the most important part of the story might be the non-story piece: there does not appear to be any reason for him to leave. The board apparently did not want him to go. ARM holds a large lead in momentum over Intel, during Paul’s watch, in the mobile market but even then the future looks promising with early commentaries about Clover Trail. If I had to guess I would posit that his decision to step down is entirely for personal and possibly sudden circumstances. That was just a guess, however.

To further speculation about its abruptness, Intel does not seem to have anyone in mind as a replacement in just 6 months’ time. For the first time Intel will consider fulfilling the position from outside the company.

In related news, Intel’s stock made a slight dip in value after the abrupt announcement. While the decline was slight it does echo the reluctance mentioned earlier and shows that even the stock market approved of Intel’s performance over the last eight years.

Dear Intel, please get someone other than Curly to name your systems

Intel's rather poorly named Next Unit of Computing is much more impressive than it sounds.  In a 4" x 4" x 2" box is a Core i3-3217U on a QS77 Express motherboard, two DDR3 DIMMs, a mini-PCIe Intel 520 Series SSD and a WiFi card which gives you performance far above any Atom powered micro machine.  Connectivity includes Thunderbolt, HDMI and up to 5 USB 3.0 ports and it is powered by a small 65W external brick.  The Tech Report were impressed by the overall performance, especially when trying out PC Perspective's favourite shooter from 2004.  At an MSRP around $300, this is a great choice for someone who needs more power than an Atom based machine but doesn't want to pay the premium for a full laptop.

"Intel has crammed a pretty capable PC into a box that will fit into the palm of your hand and dubbed it the "Next Unit of Computing." With its Ultrabook guts, we think it should've been called the Ultrabox. Whatever you call it, though, the NUC offers a possible glimpse at the future of desktop PCs"

Now Intel owns 3DLabs and they may be making better mobiles with them

Subject: General Tech, Mobile | November 20, 2012 - 10:47 AM |
Tagged: Intel, Creative, SoC, ziilabs

Ziilabs might not be a name you recognize now, but it is one you were likely familiar with at one time.  That is the current name of 3DLabs which was purchased by Creative back in 2002 and is now responsible for SoC development at Creative, especially integrating the StemCell media processor into the ARM chips which make the basis of the mobile processors.  Intel paid $30 million for physical resources and assets along with $20 million for patents, giving them the ability to move from their current solution for Atom processors, PowerVR to the StemCell architecture.  Could it be possible that with a stronger Atom that Intel might be able to power more cell phones and take a larger share of that market as well?  Check out more at The Inquirer.

"CHIPMAKER Intel will license patents from Ziilabs and purchase assets from the UK based chip designer.

Ziilabs is a UK based subsidiary of Creative Technology focusing on system on chip (SoC) designs for smartphones and tablets. While the firm has yet to register on the public conciousness, it clearly has been on Intel's radar for a while and announced a $50m asset sale and patent licensing deal."

More changes for the IT industry as Otellini joins the other departing tech heads

Subject: General Tech | November 19, 2012 - 09:34 AM |
Tagged: Intel, otellini

This may be the most amicable of the recent departures, Intel's leader for the past eight years will be stepping down in Spring.  The last eight years have seen a lot of successes at Intel as well as a few projects which did not pan out as hoped.  He is the man who oversaw Intel's chip design change from an inefficient architecture which lagged behind AMD's to their current undisputed role in the market today.  When he first started at Intel 40 years ago, the company had only been in existence for 5 years, so he has had a large influence on Intel's growth and it will be interesting to see the changes that will occur at Intel under a new leader.  Check out who The Tech Report thinks might be the next Intel CEO here.

"Wow, what is it with high-profile tech executives leaving lately? On the heels of Scott Forstall's departure from Apple and Steven Sinofsky stepping down at Microsoft, Intel CEO Paul Otellini has announced that he, too, is going to be leaving his post."

AMD's new FirePro S10000 sports two GPUs

Subject: General Tech, Graphics Cards | November 13, 2012 - 10:17 AM |
Tagged: amd, Intel, firepro, firepro s10000, HPC, Xeon Phi, 3120A, 5110P, Knight's Corner

AMD's new Tahiti based FirePro S10000 sports a little more than just a GPU upgrade it sports two GPU updates as this is a dual GPU card.  According to The Register it should run about $3,600 and need 375W to perform, numbers which make it a more efficient card than the S9000 even though it needs significantly more cash and power to run.  It is a 2 slot card, a necessity in the server and workstation world and while it does not support CrossFire it does support EyeFinity with its DVI port and four Mini DisplayPorts.

elreg_amd_firepro_s10000.jpg

The Register also got some news about Xeon Phi, Intel's answer to the HPC cards on offer from AMD and Intel.  Knights Corner is the evolution of Larrabee into an actual product, in this case two 62 core cards though not all of the cores are active. The passively cooled 5110P has 60 cores running at 1.053GHz, while the 3120A has 57 cores clocked slightly higher at 1.1GHz and sports a fan.  Both cards produce just over a teraflop of double precision floating point math, compared to the 1.48 teraflops offered by AMD's S10000 or the 1.3 offered by the Tesla K20x. Check out more on these coprocessors at The Register.

elreg_intel_xeon_phi_die_shot.jpg

"With the FirePro S10000, not only is the GPU geared down to 825MHz, but the memory is similarly downshifted to 5GHz. The memory interface is 384-bit wide on each GPU, with two blocks of GDDR5 memory yielding a total of 6GB. (This could be a little skinny on the memory for some HPC workloads, given that the S9000 card has 6GB of memory for one Tahiti GPU.) Each GPU can access 240GB/sec of memory bandwidth linking to each 3GB chunk of GDDR5 memory.

Because the card is double-stuffed, it can deliver a very impressive 5.91 teraflops SP and 1.48 teraflops DP in peak floating point oomph."

Intel's Crystal Forest, coming to a network appliance near you

Subject: General Tech | November 1, 2012 - 10:50 AM |
Tagged: Intel, crystal forest, networking

Intel's new Crystal Forest chipset includes an undisclosed embedded CPU, an 89XX-series chipset and their Data Plane Development Kit which is the SDK they've created for designing fast path network processing.  This is not a competitor to AMD's Freedom Fabric which is designed for communication within a large series of processing nodes, instead you will see Crystal Forest powering high end routers and web appliances.  Intel has designed this new chipset to increase the performance of cryptography and compression on network packets and claims it will increase speed as well as security, along with the benefits of support coming directly from Intel.  The Inquirer reports a long list of vendors who have signed on, including Dell, Wind River Systems and Emerson Network Power.

"CHIPMAKER Intel has launched its Crystal Forest chipset for network infrastructure.

Intel might be best known for its X86 desktop, laptop and server chips but the firm does a pretty good trade in embedded chips and has announced that a number of large vendors have pledged their support for its new Crystal Forest chipset. The firm said its Crystal Forest chipset will enable networking equipment vendors to shift and control more data using its chips."
