Los Alamos to Use AMD's Opteron in Linux Clusters
nuke-alwin writes "eWeek is reporting that Los Alamos National Laboratory announced it will use more than 3,300 Opteron chips in two of its Linux clusters. According to the article 'The key to Opteron, as it tries to gain traction not only against Intel Corp.'s 64-bit Itanium chip but also its 32-bit Xeon offerings, is its ability to run both 32-bit and 64-bit applications equally well.'"
Intel can't compete with the Opteron on merits alone. It will be interesting to see what they try next.
$2,306,700 and that is if they order their SCO liscenses before mid-October. I wonder whether the state of Utah won't suffer an un-accounted for nuclear accident in close vicinity to SCO's offices.
IBM did that.
We were all warned a long time ago that MS products sucked, remember the Magic 8 Ball said, "Outlook not so good"
Still plenty of floor space in the new building.
That they were to pony up millions of $$$ for free software, Los Alamos has decided to change the mission.
The new object of the project is precise targeting of the
Manhatten Project II on SCO HQ so as to cause as little collateral damage to Utah residents.
Remember, when you hear the siren, duck and cover.

"Doesn't the 32 bit compatibility need a reboot to use, then another reboot back to 64?"
Only if you are running Windows...
To my knowledge this is NOT the case. Now, it might be an issue with the OS that they are using (i.e. the OS might not be able to run 32bit applications in 64bit mode, and vice-versa).
Sorry to be bringing up a MS product, but their new 64bit Windows will be able to run 32bit programs with in 64bit OS mode, but not 64bit programs in 32bit mode (at least from my current understanding of the new product line). However, there was some performance hits, at least at the time that I read about these features (a few months back), so it may or may not still be the case now.
I am sure it won't be long for Linux to be able to run 32bit applications and 64bit applications within the 64bit OS version. Especially since MS figured out a way to do this, it shouldn't be too hard for Linux to be able to do so as well.
We were all warned a long time ago that MS products sucked, remember the Magic 8 Ball said, "Outlook not so good"
Alas that most websites don't set their servers up to survive a slashdotting. Perhaps the web would be a better place if they did.
Yeah, and you also need to reboot your Pentiums to run 16-bit code.
It is just the state of a flag in a control register. In particular, see page 68 of
AMD's Opteron System Programming Guide.
64-bit mode is enabled with the flip of bit 8 of the EFER Model-Specific Register. Otherwise it defaults to 32-bit mode. OS designers should test/set this bit just before running a thread in the scheduler, or jumping into system code as it can only be modified by code running in ring 0. This is the same way people treated the Virtual-8086 (16-bit) mode bit in CR0. In fact, you can combine the protected-mode, virtual-8086 mode, and "long mode" bits to have a variety of register-size and memory addressing modes per thread.
Fuck Beta. Fuck Dice
I don't understand why it received *interesting* rating. This is more of a flamebate.
First, Intel makes their chips where it is the cheapst. Pentium was designed from a group in Isreal. Consider the history of Isreal collabrating with Jews in US spying and steal info out of US military and companies, would it be possible that the Isrealies gov might thought about pressure the researh group to put some special circuit into the chip so they can steal more US secrets. In addition, Intel regularly ship the material to overseas for final assemblies in places like Malay. Remember that IRS wanted 600mil from Intel because Intel ship material overseas for final assembly? The IRS considered it as not totally made in USA therefore they don't get the tax credit.
Besides, if you look at motherboards, I can't find anyone making them from the US. The market is simply too compatitive. The labor along is too expesnive in US. Companies like Intel is a globalized company and they will ship stuff to where it is the cheapest. It is no better then AMD.
Personally, I believe that Intel's marketing people and Berret need to get their heads out of their collective asses and quit telling people what they need and don't need. The current slogan at Intel is "One Generation Ahead". Well, it's time to put the slogan to practice and produce some 64bit chips that is backward comp. to the existing 32bit apps and beat everything that AMD can dream up.
This is already possible gcc -m32|-m64; granted both the 32-bit and 64-bit libraries need to be available. 32/64-bit compatibility is supported in SuSE Linux Enterprise Server 8 (SLES8); and will be available in RHEL 3.0.
Debian developers are also working on a port to Opteron that does/will support 64 bit Kernel with 32-bit and 64-bit compatibility.
" It is well-known that the Opteron chips and mobos are manufactured in mainland China"
Not according to AMD: AMD Opteron(TM) Processor
All Opterons are made in Germany.
The only two fabs they they have are Dresden, Germany(fab 30) and Austin, Texas(fab 25).
Whenever the offence inspires less horror than the punishment, the rigour of penal law is obliged to give way...
All the troll/flamebait moderators must be without power.
Someone already pointed out that the Opeterons are fabricated at the Fab30 in Dresden. AFAIK, AMD has no fabs in China and I'm not aware that they even do assembly there.
But the most farciful (Note to grammer Nazi's: Yes I did just make up that word.) statement is your post is this one:
What would stop them from putting data-wrangling code into the Opteron chips?
So even if the Opteron was fabbed in China, you think that the Chinese James Bond is just going to slip in an entirely new chip design into the assembly line and none of the automated or manual microscopic inspections each chip undergoes is going to notice that there are an extra 25,000 transistors over there and these other 30,000 transistors are in the wrong place?
And as another person pointed out, Intel does very little manufactering in the USA these days. At least AMD has a fab in Texas. I couldn't find any info on Intel's fab locations quickly, but I don't recall that they have a large scale one in the USA anymore, but that's complete guestimating.
You sound as bad as the lady at work that thinks buying Microsoft is her patriotic duty!

Where are the slash-groupies? I distinctly remember being promised slash-groupies!
I saw quite a few of their new clusters ready to ship out. I had to constantly wipe the drool off my face while I watched them assemble 2GHZ dual Opteron boxes with 2GB RAM per processor. Their tech is impressive. They have their Ice Box control units and quite a bit of custom control/monitoring hardware that makes building your own cluster seem less advantageous.
They boast #3 on the worlds fastest super computers, so questions about Linux on the "Enterprise" should be easily resolved.
This Tom's hardware review of Opteron vs. Xeon is quite interesting to give a better feel for comparison to todays speeds.
It will be nice when we have some numbers to compare Itanium II direct 64 bit to Opteron, although it doesn't seem much can save the Itanic IMHO.
My Linux Command of the Day site : LCOD
...is that AMD opened their platform well enough to the LinuxBIOS developers while Intel basically told them to screw off and live with EFI. Here is what Ron Minnich had to say earlier on the LinuxBIOS mailing list.
"in two of its Linux clusters"
:)
"making it the largest Opteron system"
Two is also greater than one.
What he *actually* said was, "During my service in the United States Congress, I took the initiative in creating the Internet." Granted, it's debatable as to how much initiative he took in its creation, but he was in fact involved in legislation and funding that helped to shape it.
Whenever I see this twisting of words and facts perpetuated, it reminds me of the fools who just can't say nuclear (it's "noo-clee-ar", not "noo-kyoo-lar", damn it!!!).

The CPU packaging is done in Malaysia or Singapore, the actual dies themselves are all fabbed in Dresden, Germany.
That's a little different, since the PowerPC spec was designed to be 64-bit from the start. The MPC74xx, PowerPC 75x, and 60x series utilized a 32-bit subset of the 64-bit spec. So everything you do with the 32-bit subset is valid with the 64-bit spec.
Why would you even want to mix-and-match with Linux (or BSD)? With Windows just about all programs are propritary, so you have to run whatever you can get, but with Linux, you just have to recompile and get everything to 64-bit, no problem.
Yes, I know some people run propritary Linux programs as well, but those are rare (and it's their own fault anyhow... *nag, nag, nag* )

" I want to know how much faster 64-bit native stuff will run vs. 32-bit stuff."
1 7.html
Check it out:
http://www.tomshardware.com/cpu/20030422/opteron-
Start there and read the next couple pages. Native 64-bit runs up to 30% faster.
As far as 64-bit native q3a probably not until the end of the year when a more stable Win-64 build is available. Although there is already a Half-Life2 64-bit build running on Win-64 Alpha, which may lead to some leaked figures earlier.

Sorry to be bringing up a MS product, but their new 64bit Windows will be able to run 32bit programs with in 64bit OS mode, but not 64bit programs in 32bit mode (at least from my current understanding of the new product line).
In Opteron, 64-bit apps cannot be run under a 32-bit OS. Opteron doesn't recognize code as being 64-bit code unless long-mode is enabled, and once long mode is enabled the OS must be 64-bit (because all switches to more privileged code also switch to 64-bit mode).
Being able to run 32-bit apps under a 64-bit OS was one of the absolutely required features for Opteron, however.
(yeah, I work at amd)
I am not a sig.
When I read stories such as this, I really start to wonder what type of dumbfucks run IBM. By closing the hardware support for the 970, they've bascially prevented their chip from becoming a player in these massively parallel computing environments.
Who wants to buy 3000 IBM or Apple branded boxes when you can get 64-bit Opterons with whatever box maker you want? Doesn't that make a lot more sense to the bottom line? The most annoying part is I am sure you are bound to using IBM service contracts as part of the deal.
They are buying the cluster from Linux Networx who are a Canopy Group company Like SCO. Perhaps Linux Networks customers are immune to the SCO claim. I think it would be interesting to ask them, and Canopy who obviously support the SCO claim.
The age of WinTel ends, and the age of LinAMD begins
I dont know who was asleep at the switch over in intel land but surely that guy is one job less after rejecting the idea to use the same backwards compatibility idea that made things so successful in the 16 bit to 32 bit switch all those years ago.
Now I get to watch a chip company I've supported (AMD) for years finally succeed. I just hope they stand by and keep their good prices for performance and not start to charge more for their chips if they become top dog or at least get a lot closer to knocking Intel off their high horse.
One of the very serious problem related to building
Itanium clusters is their very high power
consumption and the associated heat removal problem.
It's okay for a few server in a room, but for
cluster trying to pack boxes is a key point of the
architecture. Apparently Opteron is not too bad
since there are dual Opteron in 1U server format
design commonly available, and it was overheating
that would be known by now, but for the Itanium(2)
cluster I know off, they never managed to get the
full cluster running without bringing either the
power supply down or the air conditionning down.
Itanium 1 was notoriously power hungry and
a common source of joke about this, Itanium 2 is
certainly better in this respect, but the clock
speed has been multiplied by nearly 3, I really
doubt they could compensate the initial problem
enough to get the new high speed chip to get back
to a decent consumption.
On the other hand Opteron seems quite better
probably getting the benefit of all the power
consumption research that AMD did during the 90's
where AMD chip were at the time consuming significantly more than Intel equivalents.
Now if someone has the time to make a search :-)
for the advertized power consumption of both chip
that would be a really interesting post

It's spelt out in full, page 225:
(...)
(emphasis mine)
So, in other words:
- SSE is twice as fast as single-precision x87
- their initial implementation of SSE2 is actually just an implementation of the instruction set, the actual execution units are borrowed from the x87 and have the same throughput limitations
- if you are writing really large code, you might get some benefits from SSE2 because of L1 savings (but your case has to be pretty borderline for that to make a significant difference, or you have to be able to interleave a significant amount of integer code with your FP code that using SSE2 frees enough decoder bandwith).
- In the future, they might bother with spending more space for more double-precision FP units (I'd think that if they can sort out the manufacturing problems, and the HPC segment seems like the area they're selling to, then it may make sense to spend a few mm to double SSE2 performance. Depends on who actually buys Opterons once the software/OS front lines are settled)
- Today's AMD64 SSE2 performance in double-precision is not going to be leaps away from their x87 stuff (unlike the P4), but you have to remember that AMD's x87 is really good.
- Don't forget that in long mode, you have 16 128-bit registers, which may help your compiler make more out of SSE2/64 code than x87 code; some benchmarks with SSE/SSE2 enabled compilers would help clarifiy whether that's the case or not.
So in short, yeah, they claim a somewhat faster SSE, but their SSE2 is mostly a "yep we can run that code too" item rather than "yep, we can run that code too, and faster to boot".You call people naive and then refer to 'the supremacy of good over evil'.. think about it dumbass.
That's right. In several email conversations, I questioned Vint Cerf about this, and he said that Al Gore was extremely important in making DarpaNet, a research tool at a U.S. government organization, into the Internet, a public utility available to all.
DARPA is the U.S. government's violence research department. DARPA is devoted to finding more efficient ways to kill people. In the beginning of networking computers together, there was no intention of benefiting anyone.
According to Mr. Cerf, Al Gore recognized the importance of a public computer network long before other public officials knew anything about computers, and made sure the public network had funding.
Some have called Mr. Cerf, "The Father of the Internet", but, as his biography says, many people were involved. Mr. Gore was the main promoter, "father", of the public utility we now call the Internet.

As a taxpayer, I demand that any spare computing power on government hardware be put to use for dedicated game server time.
It's worth the security risk.
My vote is for Halflife 2.
Not only do Intel P4 processors produce more heat, and use more energy for the same performance as their AMD counterparts, but Intel processors also have a lower operating threshold than similar-performing AMD processors, by about 20 degrees celsius.
Let's review shall we?
Intel P4: Runs Hotter, Can't handle high temperatures, more expensive.
AMD: Runs cooler, Easilly handles much higher temperatures, and are far cheaper.
So tell me again why anyone should buy from Intel.

Simulating nuclear weapons is a heck of a lot better than finding out 'the old way'. If we're going to HAVE nukes (and there's no turning back now, I'm afraid) we may as well have the right ones for the job. I'd rather have them develop 'right-size' weapons for the post-cold war era than use giant 1970's warheads on third-world dictators. I find it foolish to demand reductions in 'collateral damage' while simultaneously demanding limits on harmless weapons simulations aimed at reducing said damage.
I'd rather have 20 very accurate, very small nukes in our arsenal than the thousands of ICBMs we have now, it would be just as effective a deterrent; getting there means money and (simulated) testing.
