After 17 years at Blizzard, the developers of the Warcraft, Diablo, and StarCraft franchises, Chief Creative Officer Rob Pardo resigned on July 3rd. He was credited as the lead designer of StarCraft: Brood War, Warcraft III and its Frozen Throne expansion, and World of Warcraft and its Burning Crusade expansion. He has not announced any future plans, except to be a better Twitter user.

Of course, several projects that he influenced are still on their way, even after he leaves the company. Beyond the games, he notes that eSports and the upcoming Warcraft movie are initiatives that he looks back on with pride, in terms of his contributions.

DDR3 Overclocking World Record: 2.31 GHz

Subject: General Tech, Motherboards, Memory | July 6, 2014 - 03:53 AM |
Tagged: overclocking, memory, gigabyte

About a week ago, HWBOT posted a video of a new DDR3 memory clock record which was apparently beaten the very next day after the movie was published. Tom's Hardware reported on the first of the two, allegedly performed by Gigabyte on their Z97X-SOC Force LN2 Motherboard. The Tom's Hardware article also, erroneously, lists the 2nd place overclock (then 1st place) at 4.56 GHz when it was really half that, because DDR is duplex (2.28 GHz). This team posted their video with a recording of the overclock being measured by an oscilloscope. This asserts that they did not mess with HWBOT.

The now first place team, which managed 2.31 GHz on the same motherboard, did not go to the same level of proof, as far as I can tell.

This is the 2nd fastest overclock...

... but the fastest to be recorded with an oscilloscope that I can tell

Before the machine crashes to a blue screen, the oscilloscope actually reports 2.29 GHz. I am not sure why they took 10 MHZ off, but I expect it is because the system crashed before HWBOT was able to record that higher frequency. Either way, 2.28 GHz was a new world record, and verified by a video, whether or not it was immediately beat.

Tom's Hardware also claims that liquid nitrogen was used to cool the system, which brings sense to why they would use an LN2 board. It could have been chosen just for its overclocking features, but that would have been a weird tradeoff. The LN2 board doesn't have mounting points for a CPU air or water cooler. The extra features would have been offset by the need to build a custom CPU cooler, to not use liquid nitrogen with. It is also unclear how the memory was cooled, whether it was, somehow, liquid nitrogen-cooled too, or if it was exposed to the air.

Oculus Rift Shipments Suspended to China

Tagged: oculus vr, oculus rift, Oculus

The popular VR headset development kit, Oculus Rift DK2, is no longer available for order in China. The reason, according to their subreddit, is due to "extreme reseller purchases". In other words, because too many were purchased with the intention of selling them at a markup. They, then, ask enthusiasts to wait for the consumer version. These are for developers to develop.

Reselling product happens frequently. You see it at big sales, when a retailer sells product near (or under) cost to lure people into their stores. Unless they have a quantity-per-purchase limit, that is enforced, you will see the occasional person buying obscene amounts. Some will even tell the cashier that they intend on reselling it elsewhere.

Oculus is "looking into alternative ways to make sure that our development kits are getting into legitimate developer hands in China". Also, they claim to have not canceled all orders in China., because, "that would be messed up".

Yes, Oculus, that would be.

The Oculus Rift DK2 is still available in the other regions.

Attitude One's colourful Alamz headsets

Attitude One joins the crowded headset market with their new foldable Almaz headset with a detachable microphone which is designed to be lightweight enough to carry with you everywhere.  The bundled cables are compatible with both Android and Apple devices as well as one you can plug into your PC and simply leave for when you arrive home.  The price of €110 quoted by TechPowerUp seems a bit high but the two year warranty somewhat alleviates that investment.  If you need a portable lightweight headset with earcups this might be worth investigating as an option.

By now you should have read Ryan's post or listened to Josh talk about Juno on the PCPer Podcast but if you find yourself hungry for more information you can visit The Tech Report.  They discuss how the 64-bit Linaro is already able to take advantage of one of big.LITTLE's power efficiency optimization called Global Task Scheduling.  As Linaro releases monthly updates you can expect to see more features and better implementations as their take on the Android Open Source Project evolves.  Expect to see more of Juno and ARMv8 on review sites as we work out just how to benchmark these devices.

"ARM has created its own custom SoC and platform for 64-bit development. The folks at Linaro have used this Juno dev platform to port an early version of Android L to the ARMv8 instruction set. Here's a first look at the Juno hardware and the 64-bit software it enables."

The slippery slope of Planetary Annihilation

Subject: General Tech | July 2, 2014 - 05:51 PM |
Tagged: gaming, bad idea, prerelease, planetary annihilation

Releasing unfinished games is no longer limited to EA, many developers have picked up the habit of Early Access versions of their games and it is in danger of becoming as common as pre-purchases have.  For some users this is not an issue, beta testing can be fun if you are that type of person or have a vested interest in trying to contribute to the development of a game.  Uber has gone one step further with Planetary Annihilation, actually releasing an Early Access version of the game to retail stores with a free upgrade to the full version once it is released.  There will be many consumers that do not understand that this is not a finished game and will purchase it with the expectation that it is completed.  This will likely lead to a lot of internet bile being unleashed and bad reviews being published which is something you would think a publisher would want to avoid.  Do you think that it is not an issue or perhaps a self correcting one or do you agree with Rock, Paper, SHOTGUN that this could be the start of a bad trend for the gaming industry?  It is unlikely that this particular game will die in development and never be released but if it becomes a common trend unscrupulous publishers could slap together a demo, sell it as a pre-release and then abandon development; they've already made money so why bother finishing the game if consumers are happy paying full price for a half-baked product?

For those who prefer to play fully finished and perhaps even heavily modded games, why not join the Fragging Frogs for a gaming session

"The practice of releasing alpha or beta games as part of an “Early Access” plan is not, in itself, inherently harmful. It can be quite good for a game when developers priorities are in order and everyone is given plenty of information about what they’re getting into upfront. Planetary Annihilation‘s early access version on brick-and-mortar store shelves, though?"

Intel's Knights Landing (Xeon Phi, 2015) Details

Subject: General Tech, Graphics Cards, Processors | July 2, 2014 - 03:55 AM |
Tagged: Intel, Xeon Phi, xeon, silvermont, 14nm

Anandtech has just published a large editorial detailing Intel's Knights Landing. Mostly, it is stuff that we already knew from previous announcements and leaks, such as one by VR-Zone from last November (which we reported on). Officially, few details were given back then, except that it would be available as either a PCIe-based add-in board or as a socketed, bootable, x86-compatible processor based on the Silvermont architecture. Its many cores, threads, and 512 bit registers are each pretty weak, compared to Haswell, for instance, but combine to about 3 TFLOPs of double precision performance.

Not enough graphs. Could use another 256...

The best way to imagine it is running a PC with a modern, Silvermont-based Atom processor -- only with up to 288 processors listed in your Task Manager (72 actual cores with quad HyperThreading).

The main limitation of GPUs (and similar coprocessors), however, is memory bandwidth. GDDR5 is often the main bottleneck of compute performance and just about the first thing to be optimized. To compensate, Intel is packaging up-to 16GB of memory (stacked DRAM) on the chip, itself. This RAM is based on "Hybrid Memory Cube" (HMC), developed by Micron Technology, and supported by the Hybrid Memory Cube Consortium (HMCC). While the actual memory used in Knights Landing is derived from HMC, it uses a proprietary interface that is customized for Knights Landing. Its bandwidth is rated at around 500GB/s. For comparison, the NVIDIA GeForce Titan Black has 336.4GB/s of memory bandwidth.

Intel and Micron have worked together in the past. In 2006, the two companies formed "IM Flash" to produce the NAND flash for Intel and Crucial SSDs. Crucial is Micron's consumer-facing brand.

intel-knights-landing.jpg

So the vision for Knights Landing seems to be the bridge between CPU-like architectures and GPU-like ones. For compute tasks, GPUs edge out CPUs by crunching through bundles of similar tasks at the same time, across many (hundreds of, thousands of) computing units. The difference with (at least socketed) Xeon Phi processors is that, unlike most GPUs, Intel does not rely upon APIs, such as OpenCL, and drivers to translate a handful of functions into bundles of GPU-specific machine language. Instead, especially if the Xeon Phi is your system's main processor, it will run standard, x86-based software. The software will just run slowly, unless it is capable of vectorizing itself and splitting across multiple threads. Obviously, OpenCL (and other APIs) would make this parallelization easy, by their host/kernel design, but it is apparently not required.

It is a cool way that Intel arrives at the same goal, based on their background. Especially when you mix-and-match Xeons and Xeon Phis on the same computer, it is a push toward heterogeneous computing -- with a lot of specialized threads backing up a handful of strong ones. I just wonder if providing a more-direct method of programming will really help developers finally adopt massively parallel coding practices.

I mean, without even considering GPU compute, how efficient is most software at splitting into even two threads? Four threads? Eight threads? Can this help drive heterogeneous development? Or will this product simply try to appeal to those who are already considering it?
