Good news: Samsung's Tizen no longer worst code ever. Bad news: It's still pretty awful

Ian Bush
Boffin

There have been legitimate uses for comparing a variable to itself - in particular under IEEE754 all comparisons that have a NaN as one of the operands return false, so checking for equality of a variable with itself was a way of detecting whether the variable held a NaN. Unfortunately optimising compilers used to think "what is this idiocy" and throw it away, hence many languages contain a isNaN function or similar.

Time to rethink machine learning: The big data gobble is OFF the menu

Ian Bush

I mentally replaced ML with HPC throughout and the articles was still close to coherent and relevant. OMO the ultimate issue here is valuing programmers (both in industry and academia) with relevant specialist skills and rewarding them - that would encourage others to follow down their path.

The cloud is great for HPC: Discuss

Ian Bush

"You may want to try throwing a set of GPUs at a particular computational fluid dynamics problem to see if that architecture can handle the workload in a more effective way. If it doesn’t deliver the gains you expected, then you haven’t sunk capital into a hardware investment"

Yada, yada, yada. I take the point, effectively renting unusual hardware, but GPUs are a poor example, in academia (if not Industry) they have moved into the mainstream and any self respecting central University service will offer nodes including them. So how about FPGAs or Xeon Phi's? You offer them, great ... how much ?!?

The cloud being of use to academic HPC currently is a myth. High throughput computing, yes there is a place. But at the moment not HPC.

Fortran greybeards: Get your walking frames and shuffle over to NASA

Don't quite get why this is particularly a Fortran problem - it's simply a result of floating point maths. In fact to expect bit wise identical results for every compiler/library/etc. combination in complex codes like those discussed here displays some ignorance about the nature of the beast, and that's before we even think about talking about parallelism. And in practice for the performance these guys need your choice of language is Fortran, C or C++, nothing else will cut it however much quiche you eat, and for all 3 the floating point issues are similar.

Re: in which electrons as “heavier” and therefore able to be controlled ion shorter gates

They're not talking about the actual mass, they're talking about the "effective mass". Wikipedia has an article on it

but I admit I haven't read it to see how good it is

Chemists tend to call Molybdenum "Moly". So though inaccurate "Moly's valley" would be a possibility.

Re: Regression to the really mean

Yes there is a difference. But either will be a disaster. May wants to cement the surveillance state. Leadsom has no interest in the "common man", she merely wants to legalise the (in my opinion) tax scams she has run throughout her career - see Private Eye passim.

Nice cluster, kid. But can these supercomputing students actually predict the weather?

Ian Bush
Meh

And the software comes from ...?

"There’s a twist in the competition on this task: for the first time ever, students have to write their own algorithm to solve the graph problem. They aren’t allowed to use the reference implementation – they have to provide their own approach. Teams will be judged on the quality of their code as well as their solution to the problem. It’ll be interesting to see what happens on this application."

Good. Call me a grumpy old sod (you're a grumpy old sod Ian), but while good fun and a demonstration of problem solving ability I struggle to see the real relevance of these competitions; you simply don't cobble together your own clusters any more, or at least you shouldn't be doing. But often the software is a different matter - where's the recognition of the people who write the stuff that can actually exploit this hardware? While I've seen the names of the teams competing and we're promised videos introducing them there's not even a link to the applications web pages, let alone naming the teams or institutions that develop them.

Re: Programming skills .NE. programming languages

"There aren't that many COBOL and Fortran programmers left, and no one is learning those languages these days."

There are plenty of Fortran programmers left, and new people learning the language regularly, just not in computer science departments.

Re: Some Department of Commerce weather alert systems use Fortran

"HPC is still C, Fortran, Assembler, then C++"

Rather at the top end it's Fortran (~70%), C(~7%), C++(~6%) and other, at least in the UK. See

http://www.archer.ac.uk/documentation/white-papers/

and

Want a Brexit? Promise you'll sort out UK universities' £1bn research cash loss

Ian Bush

Re: The answer is...

"..that the UK is not a net beneficiary of EU funds. Ergo it could afford to replace all EU funding with direct funding by the UK government on leaving, out of the money saved by not propping up Eurocrats and Eastern European failed states",

NAO slates UK.gov's 'haphazard' sci-tech money-chuck plan

Ian Bush

Re: Toys for the minister to stand in front of

For that money sharks with frickin' lasers surely?

But seriously BIS does. That resource is called "The Research Councils." But because advice is given it doesn't mean it has to be listened to, for instance if it inconveniently doesn't recommend funding the ministers latest favourite new toy. In fact it might be better to reorganise things so that such advice isn't received in the first place.

Where's the recurrent spending?

And if you are buying the toys for the minister to stand in front of where, as the article mentions in passing, where is the money to keep it going when the minister returns to his club in London? in my own area, supercomputing, the real issue is not a lack of toys to play with, it's a lack of skilled individuals to help people use those toys well and the money to fund the day to day running costs. Such people require a unique set of experience and skills, yet the wages available for them are often low for such a skill set (so recruitment is hard), there is often little chance of career progression, and funding such people through grant money is often difficult. Yet without them the capital investment is simple a pile of silicon, metal and plastic sat in the corner ...

State should run power firm spam database, says... competition watchdog

Ian Bush

Oh for crying out loud

'The UK’s competition regulator wants to see a new database of utility customers set up so they can be bombarded with “targeted marketing”.'

In a time of stupid ideas this is one that truly stands out. I don't want this targeted marketing. I don't want to spend my spare time trawling through the different offers. I couldn't even give a flying one about so called "competition". I just want the right not to be ripped off. Is this so difficult?
