Actually, I fear for NVIDIA's HPC market as well. Kepler 2 in my eyes is not well suited for GPGPU, they've rather optimized it for the gaming market in order to go after AMD. I.e. they introduced much more cores, but those cores now have l

Sorry, but I have to correct a little bit here. Today's GPUs are - not simple SIMD. NVIDIA calls it SIMT (single instruction multiple thread), mostly since you can branch a subset of them, so for the programmer it does feel somewhat like th

Kepler has 8 "SMX" with 196 parallel sp threads each. For me the number of cores = the number of parallel threads, although on GPU they are not as independent, i.e. each "core" of an SMX either executes the same instruction on adjacent data

Sounds pretty good, thanks for the heads up. Now I'm curious to see some benchmarks as soon as someone puts 20 or 30 of these on a board with lots of GDDR 3 Ram :).

Ok, so that's 6.4 cores per mm^2 while Kepler has 4.8. Not bad, considering NVIDIA has already shrunk the scheduling ressources, register blocks and cache sizes per core to a bare minimum (something I don't agree with btw.).

I think NVIDIAs definition of a 'core' has some merit. First of all, they have some independency in that you can introduce branches over a subset of them, so they're not just SIMD vector units. Secondly, their threaded programming model is

Well, NVIDIAs Kepler GPUs have 1536 cores on something like 320mm^2. I can't really find the die size of that adapteva product but I'd say it comes out at a similar range. Having looked at the data a bit more: I like their specs concerning

I'm a Swiss male. Since we all have to do 240 days military days minimum (soldier grade, sometimes they force people to do more, 21 weeks is mandatory as military academy, the rest can be split up), most of the men here take one year off an

probably not any 2 engines though, right? I'd guess if the two engines on one side fail it can't recover, since it could only proceed with 1/6th capacity through the middle engines. (They have 6, right?)

Web development with Fortran. Shudder . (String handling is abysmal in Fortran so I wouldn't wish that to my worst enemy). No, but my parent was talking about deep code optimizations being almost exclusively being done in C. I'd say HPC is

by DeepDuh 14y ago
That being said, Fortran is being used equally often, if not more often, in HPC applications. The reason being that modern Fortran both gives you bare bone access to the memory structures and offers array slicing notation as well as good mu

I didn't mean that the progress we've seen is because of x86, but because of the PC standardization. Imagine if we had a couple of competing systems like IBM PC, Atari, Commodore and Mac, each with 20-40% market share, each with their own c

How about Mail.app?

by DeepDuh 14y ago
While I share your feeling about x86, I don't feel PCs have stagnated since their standardization, at least not up until a few years ago. You are certainly correct that IBM PC at first was a horrid standard and until the Win95 generation ot

I think you hit the nail on the head. Build systems like GNU Make pull information about the file system to find out what has been updated. All we basically have to do is to 1) move from an information pull to a push. (Sidenote: This is som

Yet Apple manages that part of the deal reasonably well. I'd say what's missing is an industry device standard a la IBM PC, such that drivers can be decoupled from the overall device development. It seems like low to midrange smartphones ha

What you describe sounds good and makes me want to try it as well in the future (there's stuff in OSX, mostly of the recently introduced sort, that really grinds my gears). Then again, I will probably still miss things like Spotlight, Quick

IMO quite good is an understatement, it has become the best any LotR fan could have ever hoped for. And about Silmarillion: Think about how good some TV screenwriters have become in recent years - IMO they turn out more high quality TV scri

I was thinking the same. I never had problems with Silmarillion. Couldn't read Messages from Middle Earth however, that was just not enough connection. But Silmarillion, man, that's an epic collection of stories. I think it might be a coo

You sound bitter. So other people have thought of and built parts of what jobs' team brought together, ergo Jobs was not a visionary? You can hate Apple and SJ's personality as much as you want, but don't let it blind you. Lisa and Mac inve

I agree. I'm usually one of those 'snobby' music listeners who despises pop, but that one is actually really good, especially the video is very well done with lots of little visual jokes (what with the beach image resolving in a children's

I still believe that imperative is the best paradigm to start programming. I.e. once you understand all the subtleties of for/while and branching, you can undertand a list comprehension as an abstraction on top of that, applicable for certa

That's a very good link, actually pretty much what I was asking for. Thanks!

You really hit the nail on the head with this post. I still like the polish iOS, but Apple proves that there is indeed such a moral hazard when one vendor is controlling everything. What I'd like to see the mobile space into is some kind of

Yes, like that. Oh did I mention that it uses GPGPU accelerated cloud computing?

I like your plan. Let's join forces and disrupt the gardening and bird watching space using cutting edge crowdsourced location aware mobile technology.

Well, because you can't. Mac OS in its essence has traditionally been developed for a Mouse/Keyboard combination - Keyboard only is not regarded as the "Mac way". I'd say that this is actually a pretty good match for Laptops, since the touc

I've never used it myself, but iOS has enterprise distribution as well, don't they? I think it still works through iTunes on the client side.

I always thought that one of the main UI advantages of Windows vs. OSX is the keyboard control (at least until Microsoft made it a lot worse with the introduction of the Ribbons). This might be a very cool addition to OSX! Keep at it, this
