They just made a few extra to hit this number
Let me guess, they can easily parallelize adding two arrays together, or doing matrix vector stuff optimally. This covers some very important bases, but some parallel code needs to be rethought rather than just recompiled when porting to a very different architecture.
We have code which does not use matrix-vector stuff, and works best (40x speed up on 64 cores) on fairly coarse grained, shared memory, parallel architectures. We still have not managed to make a distributed memory version (working on it), and are struggling with an OpenCL version for GPUs (working on it with GPU gurus).
Every time I have heard people claim to have tools that take all the hard work out of parallel programming, they show me examples like "add these 10^9 numbers to another bunch of 10^9 numbers". These tools can indeed take a lot of the hard work out of parallel computing, but not all, by quite a long way.
Few people can say their knitwear was used by NASA, someone give her medal!
I can essentially live with the so-so resolution, I cannot do without an nVidia GPU to run many of our CUDA programs. A fairly portable 14" with a pretty nifty CUDA punch goes a long way to ticking all the boxes for my work.
Did he have to stun them in order to get them to attend?
Sorry, couldn't resist
"Apple will also take heart from the fact that, as of yet, there are no reports of Windows Phone fanatics in China offering to exchange organs, or even their virginity, for a handset."
This could mean people are less enthusiastic for Windows Phone, it could mean the Windows phones are sufficiently cheap to be affordable without such extreme measures, or it could mean a certain proportion of the populace needs their brain seen to (or a combination of the three).
For those in need of having their brain seen to, I hear prof Gumby is a very well-known brain specialist (or was that bwain specialist?)
Wasn't that what the computer really said?
"Please be careful with it Bond!"
I bet Simon Travaglia would like these. Paint the green button red and vice versa.
I have heard of this mythical beast, apparently hailing from Bonnie Scotland as well, but, much the cardiologist's delight, never encountered it in the wild. Should this not be researched?
Physicists (and not just physicists) always want more compute power than currently available.

Tribute to the Goodies? Like a trandem (three-seater bike) as replacement for the three-man Soyuz capsule
A few bottles of Château de Chasselas from the four Yorkshiremen? To wash down the spam?
You could go further back.
could I build a Kim cluster? Might even catch up with a 80486 if you put together a few hundred.
Interesting developments, in particular the having multiple MPI tasks able to run simultaneously on a single Kepler chip. Great added flexibility.
I understand the why, it is just of no use to me. Others will probably be very happy with the machines
I will aim at a much cheaper, only slightly heavier 13.3" or 14" notebook with nVidia 520 or 540 graphics so I can run CUDA and openCL stuff (there are a few very nice ones from Asus, Samsung, and even Dell). The whole idea of an ultrabook is hobbled by the insistence on Intel graphics. For the prices they are asking they could put in a decent graphics chipset. Until Intel supports CUDA (i.e. when hell freezes over) I will steer clear of any machine with only Intel graphics.
Now there is an excuse for a HUGE monitor (or two, or three) if ever I heard one.
Seriously, nice toolkits are coming out for this kind of work. Much needed too, as parallel computing allows you to get things wrong MUCH quicker.
Some will say it is because the Merkin goverment wants to spy on them
Others will say it is because many American drivers cannot even handle a stick-shift.
Which is it?
Still like blowing things up though
And after a PhD you become Dr. Knob?
I would be willing to try the chips (and other AMD/Radeon graphics), and the newer Linux drivers. Only problem is we would have to port quite a bit of stuff from CUDA to OpenCL (which might be a good idea anyway, similar performance and no vendor lock in).
Regarding the binary nVidia drivers, I have no problems there. I rather like the fact that after inserting a new nVidia card in my PC to replace the old nVidia card, Linux runs without any adaptation, whereas Windows needs a new driver.
I must be allowed to keep up with the register anywhere, even whilst walking across the <SPLAT>
What, and miss out on free drinks and food, and any vendor freebees?
Think like a BOFH:
1. Go to the conference
2. Head for the bar
3. Wheedle/bribe/blackmail vendor into inviting you to another conference for free
4. goto 1
They are really getting the excitement in space exploration back to (near) Apollo levels.
Unless you purchase the extra extended warranty, which extends for a further 74 milliseconds for a mere 25% surcharge!!
Only while stocks last!

You do not have to sit through them. Using the DVDs as frisbees can bring hours of healthy entertainment. Experiments microwave ovens are encouraged.
Not long, rest assured, not long
You are right when talking about looking through CDs and glass blackened with soot. There are however perfectly safe solutions. My Thousand Oaks glass objective solar filter works fine on my 8" scope. I watched and photographed the solar eclipse in 1999 with that scope, and the previous transit of Venus in 2004. Baader Solar film is perfectly safe, if attached correctly in front of the objective lens. All eyepiece filters are an absolute menace. I have recently made a solar filter out of it for my kids 4.5" F/4.4 Newtonian, and my eldest son and I had a nice view of sunspots through it. All harmful UV is blocked, and the total energy levels remain quite low.
Projection is actually dangerous in most reflectors, and certainly Maksutovs, Schmidt Cassegrains, and other scopes with fast primary mirrors, as the secondary can shatter under thermal stress, and even in fast refractors I would prefer a filter as the thermal stresses might cause eyepieces to shatter. In slow refractors projection is fine, especially as multiple can watch simultaneously.
"88 percent of respondents said they are willing to seek professional help to treat smut addicition, but would prefer to do it online;"
Well obviously they prefer to do it online, that was exactly the problem, wasn't it?
I have installed Dolphin as my default browser (after trying and not liking firefox on android). No worries on that front
It is SOOOOO tempting to suggest any orangutans on facebook would be in the upper quartile of users intelligence-wise .
But we must resist such temptations, must we not
says it all!
Mimmoths preferably pronounced to sound like Inspector Clouseau trying to say "mammoth", has my vote
Am I alone in reading Mammuthus creticus as Mammuthus cretinus
Time to head home
The technique worked here, because a body heated to 2000K emits copious amounts of IR (and even visible radiation. Move an object of the same size to an orbit with a more hospitable (at least for us) 273-300K, or roughly 7 times cooler, the same surface emits 7^4 =2,401 times less radiation (or 8.5 magnitudes lower). That would make a super Earth at room temperature much harder to spot against the glare of the star.
Darn, so I cannot use my Hercules graphics card after all
Speed limit on Autobahn? Only in some places. On most stretches they allow you to hit Mach 2. I once saw a video of a Renault Espace fitted with an F1 engine hitting 200 mph on a track. Perfectly OK for the German Autobahn.
The funny thing is most Germans support a 130 km/h speed limit, but that the car industry lobbies very successfully against it.
Brilliant, isn't it. Big thumbs up to the engineers!
So the dog deserves to be shot for that?
What a result, good excuse for a pint or to this evening
(as if we need an excuse)
Should have gone for
