Re:I'd suggest really old maps
Nice ideas with great merit.
You've gotta see the "Historical Atlas of Amsterdam"
Mentioned on the MapServer mailing list
Or directly to the site HERE
The atlas shows eighteen historical maps of Amsterdam from 1544 to 2003, referenced to the present-day national coordinate system. The scans are very detailed; when you zoom in very deeply, especially on the older maps, you can see how wonderful they are as works of cartography. When you pan around a bit, they really give the impression of flying very low over the city. If you are on a fast connection, you should certainly try this with a maximized map window.

Got something to back that up?Maybe they think GCC is a piece of crap (which for high performance computing, it is).
pinkployd, you anoy me.
Do you have any kind of benchmark to back that silly assertion up? Can you even define "high performance computing" for me? If you mean scientific computing, gcc is in wide use. Do a little searching and you will find goodies like this. I'd love to see the licensing fees for a 1,000 node cluster. Put up or shut up, please.
It's all nice and good of IBM to make a compiler for their chips. I hope they can be persuaded to donate chunks to gcc and think that it would help drive their own sales. It would be silly to hold their own work on C and FORTRAN against them.
You, taking advantage of the news to flame GCC and all the good people who work on it, just shows what a nasty little troll you are. Why not spend your time constructively? I'd love to know what compilers you use to get your work done. Hey, you might even contribute to GCC in your spare time. Until then, piss off.

Re:lites
Oh, I found a little page on the sara website where it is clarified (can't get onto the intranet anymore, else I'd have mirrored some better specs). Anyway, more about TERAS here.

Re:lites
Nope, the Origin 3800 at this place has 1024 procs. That's where I worked. You're behind the times, so to speak. Europe has big fast number crunching behemoths too.

Re:Link to the ISO
If you think SARA would be impacted by that you apparently don't know what SARA is

Link to the ISO
Here's a link to the ISO.

the ultimate computer desk...
Now this is what I consider to be a proper computer workstation...

Ok... so it's 1997 technology, but you get the idea.
Plus it's cooler looking than SARA's current monster. -

Re:Sun Rays and remote XI used to work on Sun Rays too, at this place. Usually I used my newfound mobility with the Sun Rays to get *away* from annoying coworkers so I could get some work done
:)This technology has been around for a while though... I sure digged it. It's really easy when you need help from a collegue: You just rip his card out of the sunray and pop yours in. There, now he's sitting behind your desktop, looking at your problem. Very handy.

Re:The Cave (And Quake)
Hmmm,
SARA allready has it's CAVE connected to SURFNet at 1 GB/s.... -
Re:*yawn*
They are available now. See this beast. Sara's been running the system for about a year now, IIRC.

2 x 2.2 = 4.4? How about...
the machine my university has been working with. 1024 x 500 MHz = 512 GHz ?
Of course now the machine has been partitoned, so it's not quite that large, but at least there is still a "256 GHz" partition.
Keep in mind that Origin is not a cluster, but a huge mother of a single-image machine. No backplane, but instead a mesh of CrayLink/NUMAlink cables interconnecting the CPU, I/O, and Router modules. My favorite part, though, is that with the addition of a "Graphics Brick" it becomes an Onyx. Add up to 16 G-Bricks! -
TERAS has part of it's clusters running linux....
Check out SARA: TERAS' is a 1024-CPU system consisting of two 512-CPU SGI Origin 3800 systems. This machine has a peak performance of 1 TFlops (1012 floating point operations) per second. The machine will be fitted with 500MHz R14000 CPUs organized in 256 4-CPU nodes and will possess 1 TByte of memory in total. 10 TByte of on-line storage and 100 TByte near-line StorageTek storage will be available. 'TERAS' will consist of 44 racks, 32 racks containing CPUs and routers, 8 I/O racks and 4 racks containing disks.
The fun part: parts of this huge machine are running Linux :)

Re:UN can't enforce genocide laws, let alone TLDsEnforcement on an international scale is impossible. The "world community" can barely enforce a common morality with regard to mass killings, do you really expect them to forge unity on whether or not slashdot.org belongs in
.com?Enforcement on an international scale is only impossible, if all the major players in the international field decline. And even then, to paraphrase Frank Zappa: "There's more of us little motherfuckers than you are."
And about those responsible for mass killings, the international Court of Justice seems to be doing quite well regarding the most atrocious killers of the recent Balkan war, even so, that some of them are freely going there, to await justice and get it over with.
What we need a single, flat namespace that doesn't have any "distinctions." The distinctions are unnecessary, unmanageable and unenforceable. Multinationals will claim their name in all namespaces by carrot or stick. There's no shortage of domain names if you're willing to be clever. There are, however, a shortage of obvious generic name terms and trademarked names, but that would be true in any namespace.
I agree, that the current three letter TLDs are not meeting needs or wants. For instance, where I work, we originated as an university computer center, and are therefore still not-for-profit, but we do have very commercial clients, for instance, the largest national newspaper, and a large publisher. Since only the US is hesitant about using their national TLD, this poses no problem, because we use the national TLD. But imagine, soon we will lose the not-for-profit status, and, in US terms, move from
.edu to .com, and our acronym is a female first name,SARA. SO, what to do, buy out some luscious girl or her pimp, who exploits a sara.com site? Or stress the educational part of our business with the more easily maintained .edu site? Since it's sara.nl, the question will never rise, unless at some time we grow so big as to contemplate sara.int, but I do not see that happenning for some decades. And by then, we could always choose a new name, more cheaply.But with a single namespace name collisions would take place more often, resulting in money destroying court cases, so let's not go there. Simply hand over the non-country-based TLDs to the UN, and leave the other ones to the countries involved.

Used one in AmsterdamI had a go on one of these last year in Amsterdam at SARA (thanks for the play Henk) and they are _WAY_ cool!
Think 3D environment with LCD shutter goggles.
Course I'll only ever be impressed by VR when I can do real-time, fully immersive, 3D fractal fly-throughs

CAVE in AmsterdamThe address of the CAVE in Amsterdam is:
http://www2.sara.nl/hec/vr/cave/.
I went there a couple of years ago and was suitably impressed. They use several high-end SGI to control the 3D display on several walls (please don't say we could do this with PC's nowadays. You can't). You need to put SGI's 3D glasses (crystal eyes) and use a "magic wand" (a 3D mouse). Several people can enter in the CAVE and view and control 3D animations. One of the most impressive is the one about galaxies merging. You feel you are there, so to speak. Unfortunately, more software is need for these CAVEs.Maybe like in start trek, we could use these things for games. VR quake anyone?

Potential Legal ProblemsThere was one aspect of this scheme that I wonder about: The group's use of the Cray C916. I'm not sure what the policies at SARA are, but with the Crays that I work on, there are fairly severe penalties for using processor time for projects that aren't specifically approved. On one, in fact, I get the following message upon login:
WARNING U.S. GOVERNMENT COMPUTER If not authorized to access this system, disconnect now. YOU SHOULD HAVE NO EXPECTATION OF PRIVACY By continuing, you consent to your keystrokes and data content being monitored.
The rules differ between systems, but every one that I have used has some punishment for unapproved system usage. Since the article said that they did this in secret, I assume that their work falls into the unapproved category. Although, SARA's website seems to indicate a fairly open view of their system. Who knows. I certainly wouldn't risk doing it on US systems that I have access to.
