Hey! Mobo is dead...

Commiserations... But also:

Faster crunch for the new mono! :-)


I guess we've moved on a long way since the days of supercooling CPU over clocking...

Is your new machine going to be a GPU monster? ;-)


Happy continued crunch in!

Part of a solution but to my mind all still an unholy silly game and contest and for a very greedy few, our planet and everything be damned:


Can the divestment movement tame climate change?

An increasingly popular tool in the fight against climate change is emerging - "divestment"...

... Campaigners point out that fossil fuel reserves that haven't yet been extracted are thought to equal five times the amount of carbon that can be burnt if climate change is to be limited.

Yet oil, gas and coal producers are still factoring in the burning of those reserves when calculating their companies' financial worth.

A recent report by Deutsche Bank pointed out that any deal on emissions at an upcoming November gathering of world leaders "means accepting that the entirety of the world's known fossil fuel reserves cannot be extracted and burned".

The authors say that this means that oil producers will try to maximise the benefit from their product while they still can - which is why the oil cartel Opec is refusing to cut production, even though prices remain low. ...



And yet reckless oil exploration is being pushed into the Arctic and elsewhere...

How do we turn around such corrupt insanity?

... My i7-860 showed 11.1% increase in power consumption & 27.7% increase in work output when running HT on & 8 tasks.

Thanks for the good real world example. That looks to be about right for something consistent like s@h tasks.

Note that each task will individually take about twice as long to run but with twice the number of simultaneous tasks and with opportunistic utilization of CPU cycles, you see better utilization to give a higher throughput overall.

The increase in power usage is a good indicator of higher utilization (more work being done). (Or... If you see a slowdown,the higher power suggests that the tasks are too big for the CPU cache and all that extra power is being used to thrash the cache and system RAM.)

In computing it is all a balance of where in the design is the slowest bottleneck... Or not ;-)

Today, I finally lost all faith in the Justice System of this country & in light of what happened, will forever more take feminism with a pinch of salt. Feeling totally saddened & dejected at the moment as I've only just returned from the Crown Court.

I'm having a cuppa & trying to regain composure & will post my views when done so.

Please note that my posts will be extensive & that I am aware of the professionals that will be mentioned have a job to do.

What annoyed me, the victim & her family as well as many others was the manner in which that job was carried out.

I look forward to hearing about how this terrible thing is all the fault of feminism.

A new thread deserving of more focused discussion?

Noted the lack of the Union Jack... Note that lawyers make their money from the cost and payment for argument (disputing unto quagmire ad nauseam...) ... And all clients be damned...

Justice and ideals and fair play may well be an aside. Then also, there are no winners in court...


Best of luck for all,
Martin

Why do people think 'gay' is often such an effective swear word? Because its linked with feminine behavior in the minds of most people, and it has essentially a way to say that someone isn't a 'real man'.

It isn't particularly effective any more, at least not round here, just comes across as childish.

Indeed so. Culture and attitudes move on.

Just recently, we've had the positive vote in Eire (Southern Ireland) to accept same-sex marriage (despite the medieval attitudes of the church there). We've had only a minor upset from a very few about a lesbian kiss shown on the Dr Who TV series. And that all contrasts starkly with the near rekindling of the American civil war by USA southern states when an interracial kiss was to be broadcast on the old Star Trek series...


Times greatly and quickly move on, hopefully for the better for everyone, including women.

I don't think there ie even one real quantum computer today. D-Wave has sold a couple of them but they are strongly discussed and objected.Also, the very foundations of quantum mechanics are being discussed, especially the Copenhagen Interpretation and experiments are being done to test it. I've read about this in a "Nature" article but of course I cannot link it.
Tullio

I am very suspicious of the D-Wave as some very clever sales beyond reality...

They are very clever for aiming for utilizing what they call "quantum annealing".

However...

The complete lack of any astounding results from their present devices stongly suggests that they are using multiple quantum devices in an isolated and non-coherent/entangled way.


In brief, they merely have a very expensive super-cool conventional computer.

All the rest is some fantastic Canadian Marketing.

... Netburst was totally a nonsense...with its ridiculously double clocked (x2 core frequency) A.L.Us and lack of a fundamental piece of hardware: barrel shifter.
Faster PIIIs (e.g Tualatin) did have this integrated (barrel shifter was introduced dating back at the 80386 era).

The barrel shifter omission will have been one of the design compromises for the higher GHz requiring deep ("Hyper!") pipelining. Barrel shift logic is quite a long logic path and so to pipeline that up 'NetBurst'-style would likely have been too much of a design compromise and cost.


We really do need three or more good sized equally matched competitors in this game. Monopolies are always overly costly...


Here's hoping AMD and ARM (or some others) can yet even up the CPU/GPU games!

Happy cool fast crunchin',
Martin


ps:

Instead of 'NetBurst'-style, perhaps we should dance to "Gangnam Style" Yeah!!! ;-)

(There's just got to be some good viral Marketing in that... :-( )

Excellent summary and two good examples, thanks.


The very brief summary for consumers is that of befuddlement by the claimed 'x2' for the Marketing numbers.

For the developers, there is a lot of hard work needed to optimise before being able to gain any useful performance boost. Whatever number of 'virtual' CPUs you might have still rely on the reality of the real-world physical CPU cores!


All good useful stuff. Shame about what I see as the Marketing corruption behind it all.

Anyone for the higher (Marketing?) GHz of Intel's Hyper Pipelined Technology and their "Netburst" Marketing?...

The Intel HT gives a BIG boost in that you can claim to have x2 the number of real physical CPU cores available (and call them virtual cores).


The physical reality is that each physical core is 'multiplexed' to alternately (simplistically) give one CPU cycle to one virtual core and then the next CPU cycle is given to the second virtual core, and so on. Hence, your virtual CPU cores each run at half speed if both are being used.

You suffer a slight slowdown in the extra overhead for the OS to manage the Intel HT (or even to badly ignore it altogether).

You gain a small boost from being able to opportunistically execute more threads if you have software that takes advantage of that.


So... My brief summary from my experience is:

If you are looking for performance, then you need to optimise for the HT just as you need to optimise for using a GPU for example.

In very brief summary, you get somewhere between a x0.9 and a x1.3 speedup in THROUGHPUT if you utilise all available threads.

For single threaded tasks, switching HT off can give you a better/faster response.


(Note that for the recent AMD CPUs, you have real physical cores for each thread and there is an FPU shared between two cores. Very good structure for general use and for server use. For s@h, you only need half the cores computing to max out the FPUs. The other cores should then be used to support GPUs or for general running. There's some good opportunity there for performance comparisons ;-) )

Here is a breathtaking step for the slow shift (drift?) out of nearly a thousand years of self-imposed isolation for a country:


The beauty contest winner making Japan look at itself

... In just two years here I have clearly absorbed a lot of the local prejudices about what it means to be "Japanese".

My confusion lasts only until Ariana opens her mouth. Suddenly everything about her shouts out that she is Japanese, from the soft lilting tone of her voice, to her delicate hand gestures and demure expression.

Well of course she is. Ariana was born in Japan and has lived here all her life...

... In Japan the reaction to Ariana's victory has been oddly muted...

Everything we consume is genetically modified by selective breeding.

Largely yes.

However, there is a vast difference and a great difference in health and nutrition between natural selection and artificial breeding selection to boost positive natural traits...

As compared to the deliberately toxic artificial stuff and outright market manipulation perpetrated in the name of GM.


So far as I know, there have been no positive examples of GM-food. However, there are repeated examples of the environment and farming being adversely affected by the agribusiness use of GM... "GM superweeds" and environmental destruction are just two examples before we even look at what we then get to eat with the 'added pesticides'...

One final thing here, the left is (again) only a side of the political spectrum. You are lumping everything from Communists, to social democrats to environmentalist parties together. Only one of those has ever had a significantly negative impact on this planet in a few countries. Its a little insulting to lump everyone together.

... Just wondering about your obsession with just Cigs, and not other, similar products.

So what has the greatest 'slime' impact against most people?

Is there worse that such as the Fossil Fuels industry, Big Tobacco, and the GM-foods peddlers and toxic Big Agribusiness?

You are including Fiendish Capitalist's selling Pot. Lying, of course, that it is safe for most. And Pot's 'Second Hand Smoke'. Probably just as dangerous as Cig's, and has a stronger, disgusting smell.

Big, Greedy, Capitalist Pot, is just around the corner.

Or is your obsession only with Cigs, and not Demon Rum, Pot, etc.

In contrast, what I've seen is how the tobacco industry look to have deliberately and fiendishly pushed lies and deceit and their customers be callously damned.

So... Microsoft have now subverted their "patch updates" to now update you with their new Marketing. How soon to also including additions from other "trusted associates" who have bought into the Microsoft program?...

In addition to a dimension linking particles I figure that some particles in an atom are located in several additional dimensions;
(fifth / sixth / seventh, dimension etc)
This would be where all that dark mater and dark energy is hiding.

I hope we will figure this out some day, Ods are that we will wipe ourselves out before that time.

Or... There is energy 'hidden' in their vibrations that have a parallel explanation as 'other dimensions', but that are not actual 'other dimensions' in some other 'space'...

All our 'dark energy/mass' could just be that our space is vastly wobbly but only as seen at small dimensions... We are all a quiver like an infinity of wobbly jelly!

A little something long overdue?...


Global Apollo programme seeks to make clean energy cheaper than coal

... The Global Apollo Programme aims to make the cost of clean electricity lower than that from coal-fired power stations across the world within 10 years. It calls for £15bn a year of spending on research, development and demonstration of green energy and energy storage, the same funding in today’s money that the US Apollo programme spent in putting astronauts on the moon.

The plan is the brainchild of a group of eminent UK scientists, economists and businessmen including Sir David King, currently the UK’s climate change envoy, Lord Nicholas Stern, Lord Adair Turner and ex-BP chief Lord John Browne.

King said green energy already had advantages over fossil fuel power in cutting deadly air pollution and reducing the carbon emissions that drive global warming. But he said making clean energy cheaper was important too: “Once we get to that point, we are winning in all the battles.”...

... electricity from coal-fired power stations only appeared cheaper because the costs of air pollution and climate change were not included. He noted that the IMF recently calculated that fossil fuels benefit from subsidies of $5.3 tn a year, or $10m a minute, half of which derives from the polluters not paying the costs of health damage from air pollution...

... making electricity 100% renewable by 2050 would require affordable energy storage, both on the domestic scale and national scale. Storage technologies being targeted include better batteries, heat storage in water, soil or molten salt, compressed air, flywheels and hydrogen.

Sir David Attenborough, who recently discussed climate change in a meeting with US president Barack Obama, said: “I have been involved in arguments about the despoilation of the natural world for many years. The exciting thing about the [Apollo] report is that it is a positive report – at last someone is saying there is a way we can do things.”...

Tobacco giants vow to fight Canadian judgment handing C$15bn to smokers

Three tobacco companies are appealing against a “historic” decision by a Canadian court to award smokers C$15.6bn (£8.2bn) in damages.

Quebec superior court justice Brian Riordan said the companies had put profits before the health of their customers...

... called the ruling “historic – not just for the compensation for victims but also for public health and accountability”.

More than a million smokers and former smokers in Quebec were seeking damages, on the grounds that the companies knew they were selling a harmful product but concealed the risks. ...

“The companies earned billions of dollars at the expense of the lungs, the throats and the general well-being of their customers,” he wrote in a 276-page judgment. “If the companies are allowed to walk away unscathed now, what would be the message to other industries that today or tomorrow find themselves in a similar moral conflict?”...



So... There are some morals in business to be upheld? This is about people after all...
