All a game of crazy politics and the real world be damned?...


Global warming and the race for the White House

Two starkly different visions of global warming are offered by Hillary Clinton and Donald Trump...

The Democratic Party contender says she believes in the science of climate change and plans to see America become a "clean energy superpower"...

By contrast, the Republican candidate talks down the threat of rising temperatures and says his priority is to cut the costs of energy for manufacturers and to revive the coal industry...

With such sharply opposing perspectives, this is the first presidential contest in which the candidates are highlighting their stances on global warming and energy, and using them to attack each other.

So how is this playing out in a swing state like Ohio, which hosts some of America's oldest coalfields and one of the most innovative solar panel makers?...

... The pollution belching from the smokestacks has been gradually limited by wave after wave of legislation - first on emissions of sulphur dioxide, then of nitrogen dioxide, and now of carbon dioxide. It's no surprise, but along this valley the Environmental Protection Agency is held in contempt. This is the body responsible for cleaning up the air and reducing greenhouse gases under President Obama's Clean Power Plan. A key Trump promise is to dismantle both the agency and the plan...

Here, Hillary Clinton is a hate figure...

... He [Trump] sees coal as abundant and homegrown, and responsible for thousands of jobs. And he talks of revitalising the industry, which goes down very well in mining country. The fact that it is the dirtiest fossil fuel is irrelevant in the Trump view because global warming is a "hoax" as he once called it, though he later said that was a joke...



All a joke?!

So when I speak of 12 cores, I mean 6 physical plus 6 virtual on that single CPU chip.

Small nit-pick on the detail:

I would describe that as "6 physical CPU cores that are 'multiplexed' by 'hyperthreading' to implement 12 logical ('virtual') cores".

What the hyperthreading does is to share the processing cycles of one physical core between two processing threads. You never get anything for nothing and so that in effect gives you two 'logical' cores running at half the clock speed of the actual one physical core.

However... You get a performance gain if one process thread becomes 'stalled' waiting for hardware or some other CPU resource whereby the other process thread can take advantage of otherwise wasted CPU cycles whilst the first process waits.

In practical terms, this means that the two 'hyperthreads' run at anything from approximately 50% of full core speed to about 65% of full core speed.

Overall, although each process is running slower, you can get up to about 130% throughput over that of not utilizing the hyperthreading. However, you sacrifice some of the system 'responsiveness'.



The expensive GPU is where most of the analysis of the Data get done now a days. You can analyze (crunch) the data on the CPU but they tend to be much slower than doing the work on the GPU.

Is not the best advice to go for the very latest mid-range GPUs for both optimum processing power and optimum power consumption/expenditure?


And go for a small-ish SSD on the leanest machine that you can install!!

Look up the Lunatics ;-)

Happy fast crunchin'!

There might still be some hope for me after all..

Microsoft will also create security-only updates that include all the security fixes released each month, without any reliability or feature changes. These updates won't be cumulative. They will only be offered via WSUS and SCCM; WU users won't see them.

I'll see how that actually works when the time comes.

Well, well, well... Yes, I've just noticed the news for the strange moves...

This puts a total 'spanner in the works' for those wishing to vet and control what updates go onto their Windows systems... See also:


Farewell Patch Tuesday fragmentation: from October, MS will roll just one monthly patch

Downside: that zero-day is still [a] zero-month [long]

... Microsoft is implementing the monthly patch rollup it promised in May.

At the same time, however, Redmond has decided to kill off individual security patches, something that might not please sysadmins. Instead, a monthly security-only rollup will collect “all of the security patches for that month into a single update”...



So... I read that as yet another step towards "Microsoft systems" = "No User Choice".

PS: I hope to be getting rid of my one Windows system and the multiple Windows Servers support before Christmas this year. Yeah!!! :-)

Or... Cut out all the corrupt pollution or laugh at the wars of mass migration?...

Can climate denial get bigger or worse or more extreme than this?...


The climate crisis is already here – but no one’s telling us

... The media turns us away from the issues that will determine the course of our lives, and towards topics of brain-melting irrelevance.

This, on current trends, will be the hottest year ever measured. The previous record was set in 2015; the one before in 2014. Fifteen of the 16 warmest years have occurred in the 21st century. Each of the past 14 months has beaten the global monthly temperature record. But you can still hear people repeating the old claim, first proposed by fossil fuel lobbyists, that global warming stopped in 1998...

... Eight months ago in Paris, 177 nations promised to try to ensure the world’s average temperature did not rise by more than 1.5C above the pre-industrial level. Already it has climbed by 1.3C – faster and further than almost anyone predicted. In one respect, the scientists were wrong. They told us to expect a climate crisis in the second half of this century. But it’s already here...

... Donald Trump, on the other hand – well, what did you expect? Climate change is a “con-job” and a “hoax”...

... On every significant issue in the manifesto, corporate capital wins... [Our world loses.]

... To pretend that newspapers and television channels are neutral arbiters of such matters is to ignore their place at the corrupt heart of the establishment... [Our world and everyone loses.]



There is a particularly apt comment to that article for the continuing ever greater corrupt climate pollution and denial:

Ten years from now, perhaps we can have the climate equivalent of the Nuremburg Trials. Those who prioritized profit over the future of mankind could be sentenced to work on projects that mitigate the impact of the decisions they made. It won't affect the reality we'll be living in, but it will make me feel better.

The "Windows 10 fun" continues?...


So... I've FORCIBLY(!) updated a laptop I use to Windows 10... The system failed the Windows 10 Update check due to some VPN software on there... Very disruptively, I uninstalled the supposedly offending software to then be told by the Windows 10 Update nag box that the laptop was still unsuitable due to the (now uninstalled) VPN software and that I must buy a new Windows 10 laptop!!...

For the unknowing, all very nastily coercive...

So... A quick web search and some crazily nefarious voodoo forced a Windows 10 install to run.

And...

For anyone such as myself familiar with Linux systems, all I can say is what an incredible long and convoluted 'experience'! I could have installed a Linux system multiple times over from scratch!...


OK, so so far the Windows 10 seems to work. But what an inconvenient experience...


And for others' experiences... See:

Windows 10 pain: Reg man has 75 per cent upgrade failure rate

Comment As your humble HPC correspondent for The Register, I should probably be running Linux on the array of systems here at the home office suite. But I don't. I've been a Microsoft guy since I bought my first computer way back in 1984.

You, dear readers, can rip me for being a MStard, but it works worked well for my business and personal needs...

Until yesterday, that is...

Human population size is a problem.
India will surpass China in about 10 to 15 years as the most populous country in the world.
But in China the population will also decline in about 30 years from now.

The one child policy seems to work pretty fast.
At very least a two child policy would help a lot.

Education to ALL, especially women, will help even faster...

How do we improve all our cultures to give better education and better stability so that there is no need for large families...?

And then how do we re-educate economists to work with zero growth rate rather than contriving perpetual growth unto an inevitable disastrous crash?...

Good that a new kernel worked.

Which kernel version did you need to move up to to get it working again?

(I guess a 2014 distro is nearing end of support? Or is that one a "LTS"?)

The problem is, as I've stated in this thread once before... I don't trust that updated client to not go behind my back and install stuff I didn't authorize it to do, as some of the other versions of the client have been discovered to do.


At a whopping 2.5GBytes... Is that by any chance the compressed size to install the guts of Windows10?...

Rather odd to 'hide' that in a service process... Are not 'background services' supposed to be small and fast and unobtrusive, so as to be in the background and be unobtrusive and provide an efficient service?...


Or is this some new 'abuse' similar to how some executables are 'hidden' in the Windows registry and other places where executables simply should not be found!...?

Having a gun will protect you.

If you are in an environment where you 'need to have a gun'...


THEN EXPECT TO GET SHOT.


It's that simple.

Simply remove the guns for something better.


Geee-whizz... Is that why I turned down a job in the great US-of-A?...

That and the homophobia, xenophobia, and silly long work hours expected regardless of results and regardless of merit. I actually got the comment from a boss saying "Geee, you're too happy, we're not working you hard enough!"... Not that actually, good working made things work well...


Only in the USA...

Good luck!

When do we turn around the lingering old fossils pollution and the corrupt big agribusiness?... How soon?...

ML1, the answer is quite simple, when cleaner alternatives are cheaper in the short term. After all most of the specie seems to have only a short term perspective.
One way to do it with a tax, highly unlikely due to political reasons. The other is better more cost effective green technology.

No tech solves this except birth control. The sooner it is admitted, the sooner the solution is upon us.

While I agree, it isn't quite so simple, the western financial model is built on there being an increase in population so that health and pensions can be financed to increasingly long lived population.

Probably a Catch22 situation as it is education and better health care that led to the increase of lifespan.

And that leads to another political problem, with better education and health care this population sees no need to have high birth rate, so increases in population are met with immigration.

... And better education leads to a lower birthrate as is shown the world over.

Unfortunately, for any political or financial 'crisis': Science, education and the environment are the first to get trashed.

A poorer education and poorer environment are also strong factors that promote a higher birthrate... (To offset the game of (expected) mortality...)


Rather a bad and unholy game...


Can we promote better education and a better environment FOR ALL?

(That also means getting rid of the corruption and pollution...)

Yet more global warming effects that are plain to see across an ever wider view... Just look up in the evening sky with your own unaided eye:


Climate Change at the Edge of Space

... we call them, “noctilucent clouds” (NLCs). They appear with regularity in summer months, shining against the starry sky at the edge of twilight. Back in the 19th century you had to go to Arctic latitudes to see them. In recent years, however, they have been sighted from backyards as far south as Colorado and Kansas...

... These results are consistent with a simple model linking PMCs to two greenhouse gases. First, carbon dioxide promotes PMCs by making the mesosphere colder. (While increasing carbon dioxide warms the surface of the Earth, those same molecules refrigerate the upper atmosphere – a yin-yang relationship long known to climate scientists.) Second, methane promotes PMCs by adding moisture to the mesosphere, because rising methane oxidizes into water...

... Summer is the season for PMCs and noctilucent clouds. As June turns into July, observers in Europe are already reporting some displays, and they should appear over the northern USA within weeks.

Observing tips: Look west 30 to 60 minutes after sunset when the sun has dipped ~10 degrees below the horizon. If you see blue-white tendrils spreading across the sky, you may have spotted a sign of climate change. It happens, even at the edge of space.

Hey, it's good to experiment!

I tried a physical KVM switch a few years ago. One plus point is that it keeps things conceptually direct and 'easy'. Minus points are the mass of cables needed and that you can still get yourself confused as to which machine you have (inadvertently) selected!

Since then, and since all my machines are on a Gbit network, I stay settled and comfortable on just the one physical machine and use the various remote connections available on Linux to work with all the other machines (including for my normal work where the machines can be hundreds of miles away).

I try to set things up as commonly as I can (with 2 Debian stable64, 1 Debian stable32 and 1 Gentoo64), and all the users in question are in all the right groups. The Debian32 is going to get updated to Debian64, and the Gentoo is going back to Debian


Very good idea to settle on what you like until you wish to explore further.

I learnt through the DEMO-Linux, Mandrake, Mandriva, Magia route for the 'desktop' Linux distros. Various others were used on odd occasions also.

Alongside that selection, I've moved almost entirely over to customised Gentoo systems, often with no desktop at all!... Works very well but that is quite a lot of new things to learn to move from the other very well packaged 'desktop' Linux distros.

For getting GPUs to work for Boinc:

  • Use the version of boinc that is packaged with the Linux distro;
  • Check the system power settings to set what happens when there is no human activity!
  • Check whichever forums for your distro and the questions forums here for any comments about running boinc.



In the Windows world, some users have to make a dummy video plug to fool the graphics card electronics (or the Windows drivers?) into believing a physical monitor is connected. Is that still the case or has that problem 'gone away'?

Myself, not seen that problem for any of the GPU crunching done here across a mix of VGA, DVI and HDMI graphics cards.

Note: Boinc can get disconnected from the GPU if you are running Boinc as a yourself as a user and you then log off or allow the system to go into sleep or whatever powersaving mode.


Go with 4.6 kernel systems for perf and the various other kernel tools... A lot has happened since the previous versions!

And see:

All the performance monitoring tools in Linux and their functionalities in a single pic


Hope that gives a few clues,

Happy cool crunchin'
