Tens of nanoseconds
The speed of light in vacuum is ~30 cm per nanosecond. Roughly one foot. That would be three meters per "ten of nanoseconds". Since Tianhe-2's layout is 27 meters on a side, 38 meters from corner to corner, that would be over 100 nanoseconds from node to a distant node in the best case, which is no longer "tens of nanoseconds". It's probably best if we assume a spherical datacenter or a smaller footprint if we are to believe this figure.
I will believe it
When I have the thing in my hand and it performs as advertised. We've had press-release mobile engineering from this one for many years.
Re: SATA attached flash still?
Does it boot?
Ineffective online ads?
I do believe that there are a number of antitrust suits in the US and the EU claiming that Google has such a monopoly on online advertising that if you don't buy adwords your online business literally does not exist.
I think that being the defining edge of existence is, by definition, "effective" as far as the ad business goes. "To be or not to be" and all that.
SATA attached flash still?
Come on Intel. You know better than this. PCIe attached flash is where you want to go. Cut out at least one level of abstraction between the CPU and the storage, and eliminate the unnatural bandwidth and latency limitations of SATA/SAS. This was a great answer five years ago.
Oh, yeah. Windows doesn't support it. You're not going to let that go, are you? Even as they sling ARM tablets. Fine. Reap what you sow. We'll get our stuff somewhere else.
Thunderbolt though, that's your baby right? Could you at least put some flash cache in a Thunderbolt 2.0 attached DAS array for the consumer? Something with 10 bays and RAID 50 at least? Now that they have Android tablets the kids are generating about 40GB a week of HD video - most of which nobody is ever going to see but we'd love to save it so we can pick through it for the embarrassing bits to include in their wedding reception video some fifteen years hence. It's sad to have to keep deleting those precious moments. Slip your new Atom in there.
That would infringe Attachmate's trademark.
Re: @ MIkel -- I Am Sad
Don't be an idiot. Racial oppression is so far out of scope for the NSA as to be laughable. The NSA is a highly effective organization and their only concern for racial tension is its use as a tool. Their purposes are 1) don't get caught and 2) identify threats to US national security. They don't care if those threats are the SLA or the IRA. They could literally not care less about black on black, black on white, or white on white violence any more than they care about your porn preference for transgender albino dwarves if that's your thing. They also know about, and don't care about, the myriad ways you cheat your employer, your business partners, your drug dealer, your "mistress" and the taxman if any of these are true. They could have a camera implanted in your head or be monitoring your XBox Kinect and unless you were plotting harm to the US you have nothing to fear from them no matter what color you are. If you were though it's their job to know no matter where in the world you are and to do the necessary to find out - even before you know, if possible.
Do I approve of the depth of their coverage? No. They've gone overboard on the "effective" thing. But these are difficult times. To call them racist though? That's just dumb.
And yes, they are reading and indexing your post and mine. Probably the draft submissions too.
NSA is a global thing
I've never seen so many El Reg comments on one article. I can't be bothered to sort them all and see if this has already been posted.
The US NSA operates globally. If you think your Bangalore or Libya or Tehran-based cloud is immune from their monitoring you are mistaken. Avoiding US clouds does nothing to get you away from them. Knock yourself out.
They are not even the only US spy agency that does so. There are at least seven. Some are not even on the books. A lot of the time they're spying on each other.
What I'm surprised by is the sense of surprise. Didn't you all know that there was a significant fraction of the global GDP dedicated to everybody spying on each other? That these agents are bound by no law except the primitive "don't get caught"? This is not a new thing and the US is not exactly the worst offender.
Re: I Am Sad
I am sad that you ever thought this way. I had thought this level of naivety predated me. That people don't expect this level of spying is remarkable because they demand it. It is, I suppose, an ironic loop.
The US has more than 15 spy agencies of which the NSA is one. The NSA's whole purpose is to spy on people in America. To announce at this late date that they are doing that and freak out about it is quite naive. That is what they are FOR.
Whether this is needful is a different question. I think yes.
Regardless there has always been and always will be an organization devoted to extracting all possible hints of threat out of the public discourse. And there should be.
If you want to do something about CO2 emissions how about you feed your Gulfstream private jet into a chipper?
+1 for the headline.
Not a products guy
Responsible for managing Microsoft's internal IT, with no upward mobility. Five years and done is about what you would expect for that role.
I like dogging the Beast as much as the rest of you all, but this looks like a pretty straightforward deal.
Windows... on a tablet
Can you believe it's been a running gag for 18 years already? Where does the time go?
Ah, I remember the Enderle days
When all it took to be an analyst was a website and a list of "reporters" who could be trusted to republish your spam without too much editing.
Whatever happened to Enderle anyway? Did he take up fishing or something? And that other bloke... what was his name... crud I forget. The patents guy. And Manuel Icaza, whatever happened to him?
We're still talking about tape?
There are worse things to be convicted of than getting a bit on the way.
Shame about the car though... and I hope the lass is OK.
Re: we either resource limit ourselves
Malthus was right as will be proven eventually. He underestimated our ability to discover new ways to grow food. Ultimately he cannot be wrong because it is a truism that we can outgrow our planet. Like bacteria in a dish we will eventually exhaust the energy available in the dish and die - unless we escape the dish.
If you want a stable climate
If you want a stable climate then you could do worse than the Jurassic when atmospheric CO2 was over 1900 ppm and the Earth's climate was fairly stable for 60 million years. Unlike now when we dip into ice age climates for 150,000 years of every 165,000 - wiping out vast swaths of species including man on a regular schedule, glaciers sweeping the evidence into the sea. Strangely enough estimates have temps in the Jurassic period only 3C above current levels. Something tells me the archaeologists haven't been talking to the climate wizards because their numbers don't align.
They have discovered the oceans are thermal sinks now. Nice.
The figures they have for ocean heating though, they compute to an atmospheric heating of about 90C. I'm pretty sure that didn't happen. They're counting ocean temps for carbon sinks now, but I don't believe they're correctly accounting for the thermal variation in solubility of CO2 in water. It turns out that cold water holds SCADS more CO2 in solution than warm water does. In fact, that sort of explains the "atmospheric CO2 as a lagging indicator of warming" as the warmer water gives up its dissolved CO2 to the air. That water is as cool as it is because 15,000 years ago when it had been cold as a Republican's heart all over the planet for 140,000 years the oceans had become cool enough to absorb far more CO2. It takes a long time for that much water to heat up after the Earth's orbit comes to a warmer clime for the brief interglacials like the one we're in now. As the cold deep water surfaces and warms in warmer sun after up to 1600 years it's going to give up some of the CO2 it captured long ago. It takes many cycles to give up it all because most of the water isn't in a conveyor and the CO2 blanket keeps the air and sea warmer even as the orbital cycle has moved to a cooler zone.
They're including solar cycles too now, and orbital variations. That's nice because the Sun's periodic variability and the Earth's varying orbit are "settled science" in hard sciences. The Earth has moved out of our "sweet spot" where men can live in current numbers but it will take a while before our CO2 blanket is depleted. Wait until they hear about geothermal energy. They're going to have to "adjust" again.
Seriously, it's nice they're starting to refine the models to include some basic primitives that should have always been in there. Another hundred years and they might be able to be able to make a nice reliable prediction. By then it ought to start getting cold again and the fall into the ice is rather steep. Frankly climatologists need to get some instruction from thermal physicists on the quality of data from a thermocouple and the meaningfulness of averaging data in excess of the instrument's ability because they have their statistical analysis all wrong. The mean of many points of ignorance is not "data". At the level of their reportage the data is random. They rely too much on statistical analysis.
What is amazing to me how despite decades of "settled science" we keep getting these huge admissions that "we didn't include or correctly calibrate this overwhelming factor that hoses up our predictions" about every three months. If you add up all of these corrections for the last few years they make more than 100% of the result. Yet the science is "settled". The toe of that hockey stick was a ski jump to some astronomical projections and now it turns out it was an anomaly if it was even more than an observational error artifact, or data manipulation. Nobody screaming "settled science" now wants to talk about the thermal cataclysm that didn't happen back when that was "settled science".
Still folk feel free to write fear-mongering articles like Phil Plait's recent The Arctic Ice "Death Spiral" that dramatize the issue with phrases like "ice-free Arctic by 2040" without mentioning they mean "at the height of summer, for 15 minutes". "Death Spiral?" Really? And without mentioning that Antarctic ice is increasing so the net ice balance is the same - so no global net energy transfer whatsoever. Really, I expect more science and less art from Phil. Maybe he should stick with astronomy. He's good at that, and shouldn't turn his fame into a bully pulpit about stuff he doesn't understand.
Frankly, +2C isn't quite enough for me. I would like +6, or even +8. Thankfully after we run out of oil and gas we have Methane Clathrates to keep us warm and turn the wheels of industry. Evolution has found a way to prevent oil, coal and gas, but methane clathrates can be farmed. We might yet keep the planet warm enough to sustain our culture through the next cold period. That should get us to 40 billion humans, self-sustaining interstellar colonies, fusion energy and the like. If we don't kill each other first.
If you're in a position where sea level rise is threatening your imminent demise you should turn your back to the sea and walk forward 20 yards or so. If you can't walk then roll your wheelchair or crawl or flop or ask the person who brings you food to drag you. There. Now you should safely meet your end from some other cause when your time comes.
It's early yet
As we come to the end of the year it's likely the pace of change will continue to accelerate. That means by March the news should be right horrific for PC makers on actual "PC" units for this year. But that's OK, because they'll all be making tablets as fast as they can. Right?
PC makers have been killing each other on margin for a long time, hoping to gain dominance and "win" the right to charge a premium price. Well, here we are at the end. "Bob, tell them what they've won!"
7" tablets have come under $100 for the quad core, Android 4.1 version. Remember that "$100 laptop" thing that was going to revolutionize education? It's here. Now.
We can go back to PC buying once everybody has a nice new tablet. Or three. Or not.
All of the security companies have in their license agreement something like: "You accept that we have no chance in Hell of delivering actual security."
these are different schools
They should have an air gap.
Network security isn't any worse now than it ever was. And it's no better. Also, Unicorns are neither more nor less available. All of these are mythical objects having no substance whatsoever.
"The 4TB drive 3.5in DVR HDD costs $75.99 on Amazon or $79.99 on New Egg, we're told."
I'm afraid I'm going to need a link to that. Anybody?
Google already ate Oracle's lunch. Oracle sued and Google won. Have you been asleep for a decade?
Cross platform compiler tech is high art. That's why we revere Dennis Ritchie so: not only did he do it, he made it look easy. 40 years later we can't simplify his work because he reduced it to least principles before publishing. Every derivation of his art we try to advance the field leads to self-defeating complexity. He is the Einstein of code.
The explanation for Ballmer
"The luckiest dorm room assignment in all of recorded history."
The guy is retiring in 2017. Leave him alone. He's got a lot of work to do.
Nokia is not a top 10 smartphone OEM any more
Until they are again how about some articles about the up-and-coming all-stars instead?
You are about to get your wish
Next time be more careful how you phrase your wish, as the result may not be what you wanted.
He could be right
$200 Android laptops are coming in the back-to-school season this year. Some with ARM, some with Intel.
Hopefully they'll not go down the same stupid 1024x768 non-touch display dead end as low-end Windows laptops or they're DOA. Nexus 7 this fall will have a 1920 x 1200 7-inch display at $200.
The problem with his thesis
If as he says Windows 8 is a fabulous OS and customers everywhere are eagerly embracing it, enthralled by it... then Frank X. Shaw is the worst "corporate vice president of corporate communications" ever. Because an effective "corporate vice president of corporate communications" would not have to keep coming before the press to say "hey, guys, I don't know if you noticed but... we're not dead yet."
I am also not finding the Intel connection
Intel's care of Dr. Hawking is compassionate, not political. And not compassionate for Dr. Hawking, but for the future generations he might yet inform. Also, it is a goldmine of research into care for others of this sort.
Not seeing the Intel connection to the politicized situation here.
Executive orders are policy of all executive branch agencies
This is not some Congressional "Sonny Bono day" suggestive recognition. This is The Boss telling his crew that this is how we do business. Likewise the whole prior pubic access to research thing. Good stuff this.
I'm torn about this. On one hand the Prez is dishing the open digital bits, on the other he's appointing people to head Justice and the FDC directly from Hollywood and the BSA. It's like he's Schizo or something. The left hand is not cooperating with the right hand.
Re: What is vs what should be
Doesn't want to get caugh misleading the market with phrases like "we are hopeful that..." when he knows all hope is lost. Could increase his exposure to criminal prosecution.
So here he is... "all along now, over the cliff we go. You there in the rear - no stragglers." But he is a billionaire and isn't going to miss a meal no matter what. Probably laughs himself to sleep at night.
Re: Must try harder?
The other developers who already had youtube apps in the Windows Phone store must be feeling warm and fuzzy about their commitment to Microsoft's platform about now.
Re: That horse is dead.
Precisely. The reason why Microsoft is not doing well in mobile as mobile takes over the world is very simple: We don't like them any more. We have seen them head progress off at the pass for 15 years, and we are ready to escape from that.
Aside, all this fluffing isn't going to get ElReg invites to their launch events, nor emails returned. They don't like you either.
Re: How strange
This joint venture is the Nook.
We were already scheduled for an extinction event
It's called the "end Holocene", a return to the predominant glacial conditions of the Quaternary age. We might not have totally escaped it yet, but it's looking increasingly likely.
Re: The underlying trend is cooling
The joke was about desperately hoping to end the Holocene and have everybody freeze to death. That last bit wasn't part of the joke.
That's just an observation: there is money to be made, and there are regions like Russia and Canada that would wholeheartedly embrace a world that's 8C warmer. Have a look at a globe sometime. There are other places that just don't care as long as they can boil their water today. Since reducing global CO2 output requires the simultaneous cooperation and discipline of everybody on the planet - many against their own immediate self interests - it will not happen short of a global unified totalitarian government that is not to be wished.
Take coal for example. What with the US now has oil and gas coming out their ears there is not as much need to burn coal for power generation. Are the mines shutting down? No. Oil is powering trains that take the coal to ports, where it's loaded on ships that burn the worst sort of oil as they steam for foreign ports.
