NVIDIA Tegra K1: First Mobile Chip With Hardware-Accelerated OpenCL

Vincent77 Tools available? (52 comments)

Does it have tools support for OpenCL? For Geforce there is no tools support and without it, and I've found out the hard way that it's too difficult to make it perform without proper insights that tools can give.

France's 'Culture Tax' Could Hit YouTube and Facebook

Vincent77 The US car industry (314 comments)

If you have to subsidize it, then it ain't culture; it's history.

Don't bring up the US car industry her. That's mean.

Nokia Design Guru Urges Apple To End Cable Chaos

Vincent77 Re:Overview of Apple connectors (791 comments)

You are only repeating what the others already said. I thought Apple-users were original (think different) and found the environment important, but it seems neither is true - you all think the same different and don't give anything about the environment. You only care about design-decisions.

Doesn't matter. Just updating my image of Apple-users.

Nokia Design Guru Urges Apple To End Cable Chaos

Vincent77 Overview of Apple connectors (791 comments)

Say there are 1 million users who just bought latest iPhone and want to have spare chargers. That is extra income of $ 10 Million! In case they used micro-USB, this would have been $ 0.

I think laptops will be next. Not only MagSafe -> MagSafe 2, but all laptops have too many different connectors.

Nvidia Releases Tegra 4 Powered SHIELD Handheld

Vincent77 Re:Not that fast at all (81 comments)

Thanks for the link. Release date of iPad 4 is December 2012 (!) and has a much higher resolution to handle. Snapdragon 800 was designed for use in a (high-end) phone. The active cooling suggests Tegra 4 is not fit for mobile devices - I still think the reason for this device is to dump their unsold processor tech.

I have to say I would welcome mini-computers in the range 15 - 30W. For notebooks this Tegra 4 would be interesting.

Nvidia Releases Tegra 4 Powered SHIELD Handheld

Vincent77 28.8 Wh battery (81 comments)

The battery is huge! An Iphone 5 has a 5.45Wh battery. With that battery the iPhone would easily survive over a week.

Nvidia Releases Tegra 4 Powered SHIELD Handheld

Vincent77 Not that fast at all (81 comments)

According to Anandtech only 74.8 GFLOPS - comparable to an iPad 4. Other sources say 96 GFLOPS, but only when in power-hungry overclock mode: image. The real winner for Q4 2013 will be the Qualcomm Snapdragon 800 - 129 GFLOPS. That leaves Tegra 4 completely in the dust.

The main reason the Tegra 4 is in no tablet/phone, is because Tegra 3 real performance and power usage was worse than advertised/marketed, and therefore the tablet/phone makers did not trust Tegra 4 would be a good bet. Another (smaller) reason was that NVIDIA is quite pushing their own agenda and brand, whereas other vendors do not meddle with their customer's business so much. Unluckily they did not learn from their experience and suggest in their latest video (the face-demo) that Tegra 5 uses 2 to 3 Watts when under full load - truth is that the load was not given. NVIDIA knows a little too much about marketing...

Harlan: a Language That Simplifies GPU Programming

Vincent77 A marketeer wrote the article (195 comments)

There are several languages that are written on top of OpenCL - that is the whole idea of this API. But if your read the article, it seems this guy was the actual inventor of the wheel.

Same response happened when some guy made Rootbeer and let some marketeer write an alike article. It was suggested that you could just run existing Java-code on the GPU, but that was not true at all - you had to rewrite the code to the rootbeer-API. This Harlan-project is comparable: just beta-software that has not run into the real limits of GPU-computing - but still making big promises that in contrary to their peers they actually will fix the problem.
I'm not saying it can be in the future, but just that this article is a marketing-piece with several promises on future advancements.

Check out Aparapi and VexCL to name just two. There are loads and loads of these solutions - many of these wrappers slowly advance to higher level languages, and have been in the field a lot longer.

Shapeshifting: Proposal For a New Periodic Table of the Elements

Vincent77 More missing elements, to to be discovered. (87 comments)

The logic of the table is that it predicts missing elements really well. Does this circular table do the same?

Ask Slashdot: What Should a Unix Fan Look For In a Windows Expert?

Vincent77 That's easier than maintaining Unix boxes (454 comments)

When there is a problem with Linux, you fix it. When there is a problem with Windows, you replace it. Make sure you have updated Windows images - this is possible by making a daily image of the system in VMWare is alike. Tweaking of software like databases is possible, but it is cheaper (in terms of hourly price) to just buy more memory and more processing power. Actually these tricks do pretty well on Unix-systems too as an extra solution. As you cannot look into the code, you have to trust others. So make sure you have a good firewall and antivirus-software. I'm not tryng to make fun of windows here; Windows is a black box, so you need to treat it as such.

Court Rules NSA Doesn't Have To Confirm Or Deny Secret Relationship With Google

Vincent77 And a server from the USA is hacked by Chinese? (119 comments)

It starts to bug me. Why are there two types of investigation? 1) "The hacker could not be traced as probably several servers were used". 2) "The IP was from China/Russia, so the hacker too". So since it is politically useful to the Americans to point at China, I suggest all hackers to get one of the computer in China. Best is Russia last with all logs at max, then China, then the usual.

Iran's Oil Industry Hit By Cyber Attacks

Vincent77 ...until the US attacks yet another country? (115 comments)

There is one country that has most of the nuclear warheads, Interfered in or even started most of the wars in the past 20 years, and is not silent on their goal for world-domination, and guess once, it is not Iran.

'Vocal Fry' Creeping Into US Speech

Vincent77 Dominant behavior (331 comments)

Speaking at lower frequencies is a sign of dominance. See Animal Planet or http://center-for-nonverbal-studies.org/tone.htm If something changed over the past decades is the feeling of dominance by the USA - that reflects in various ways, so it seems.

US Funds Aggressive Tech To Cut Solar Power Costs

Vincent77 Re:A world leader as a disruptive patent troll? (272 comments)

Agree. The title of this post is also very annoying, especially the word "aggressively" - as if people with big budgets will solve this problem where people with big *brains* have been working on for ages. And also... which money is in the fund? Money borrowed from Japan and China with which the USA tries to force to default with? Come on, USA, focus! Focus!

Microsoft-Skype Deal Poised To Win EU Approval

Vincent77 #ifndef _WIN32 (63 comments)

Developer: "Sir, I have fixed the issue that I could not manage to compile try-catch clausules on Linux". Interoperability is not something MS is good at: it works perfect on Windows, works ok on other systems. Sends us back to the era where Linux-users got sold cars with 3 wheels and the conversation with the salesman became sort of funny. As probably mentioned by others, the latest release of Skype isn't that stable and I have a clue the word "keep" in "keep interoperable" will be a nagging word in the future of Linux-releases.

Marx May Have Had a Point

Vincent77 Stubborn Exceptions? (1271 comments)

Most modern economies are a mix between socialism (healthcare and caring for the elderly, weak and poor) and capitalism (independence and freedom). Communism (independence-void) is an extreme form of socialism and corporationalism (care-void) an extreme form of capitalism. It took me a while to see that the current shift to corporationalism is breaking our freedoms more than we want to see - and still... we just shake our heads about "the brainwashing methods of communism" when reading articles as above. For that reason always vote for "extreme middle" to get a real stable system (referring to Van Kooten en De Bie, but very serious about it).

GPGPU Bitcoin Mining Trojan

Vincent77 Re:Why? Bitcoin and Slashdot? (258 comments)

Exactly, as paper money (money backed by "stocks" and other emotional products) works the same way. I like this project as it explains the "normal economy" with stocks has exaclty the same design-flaws - and you point them out quite well. Since bitcoins I start to like the sentence "In money we trust" (or was it god? they get mixed up a lot).

Google blocked OpenCL on Android 4.3

Vincent77 Vincent77 writes  |  about a year ago

Vincent77 (660967) writes "Thanks to the work of ARM in the beginning of this year, we could use OpenCL on the Nexus 4 and 10 and starting to port the various libraries to Android, initiating the same revolution of accelerated software on smartphones and tablets as we had on the desktop. Google was not happy with the competition for their RenderScript Compute and abruptly blocked access to the OpenCL-driver in Android 4.3. Noteworthy is that Google did not have the choice to simply remove the driver itself, as ARM implemented the RenderScript-compiler on top of OpenCL."

NVIDIA abandons open standard OpenCL

Vincent77 Vincent77 writes  |  about 2 years ago

Vincent77 writes "To keep NVIDIA from undermining the open standard OpenCL for parallel computing on GPUs, CPUs (via AVX and SSE), FPGAs and ARM, a petition has been initiated to call out for support for the standard:

Nvidia is not including OpenCL samples in the latest CUDA SDK, focusing more on CUDA instead. As a Khronos member with an excellent record in implementing and promoting standards like OpenGL, this is a surprising and unacceptable behavior from Nvidia.

We, OpenCL developers, humbly request that OpenCL samples again be included in the SDK. Industry standards like OpenCL help in building up a bigger market for GPU computing, and will be beneficial to Nvidia in the long term.

In a presentation for a small group the unofficial statement was that they want to sell chips *now*, and not wait for a standard to mature: "For NVIDIA OpenCL is not the answer". The remark that OpenCL can be extended to support these needs, was answered with that you don't want unportable code. Funny is that you can use #IFDEF in such cases, but not if CUDA-code needs to be mixed with OpenCL.

This is just a matter of increasing their profits, while making it hard for coders who want to make performance-code for all modern hardware."
