Re:Heating issues? (Score:3, Informative)
The reason why this is a good thing is that modern processors do not generate their heat evenly, so you might have the bottom left 25% of the chip generating 50W, while the other 75% of the chip is mostly idle, only generating a few watts here or there. This is a bad thing for a variety of reasons, beyond the obvious fact that one area has to be cooled more than others. When it comes to actually dissipating the heat though, what you want is to get this heat into the furthest corners of the heatsink as quickly as possible. This is why copper inlays are a good thing for heatsinks (they spread the heat away from the hot core towards the edges of the heatsink faster than aluminium does), however even aluminium conducts heat a lot better than the P4's heat spreaders do.
This sort of thing is, presumably, less of a problem for the Athlon as compared to the P4 simply due to die sizes. The P4 is a MUCH larger die (nearly twice the size) when compared to the Athlon. So, while the distance between the hottest and coldest points in an Athlon are always going to be quite small, they can be relatively large on a P4.
As for fixing the heatsink to the motherboard instead of the socket, this is a damn good thing if you ask me. AMD originally thought that this would be how things would be done with the Athlon, and specified 4 holes around the socket to do just such a thing. You can even buy heatsinks that attach this way (my Athlon is cooled by just such a heatsink, an Alpha PAL 8045), however the vast majority of heatsink designers just flat out ignored these holes and just attached to the heatsink. Intel was a bit more forcefull, and absultely required ALL heatsinks to attached either to the motherboard or even to bolt to the case itself (the first P4s, those that came in a socket 423 package, required a special case that the heatsink bolted on to). Intel's currently design of using clips to clamp the heatsink down to the motherboard is a fairly good one IMO, though it does put an awful lot of strain on the board. AMD's plan for the Hammer/Opteron is similar, and it looks like they're going to try to avoid some of the motherboard bending/strain, however it remains to be seen just how well it will work in practice.
In any case, it remains to be seen just what the power consumption of the Hammer processors will be. The only thing that is for certain is that they will use a LOT less power than their Intel counterparts (which, in this particular case, are the Itaniums, which use roughly twice as much power as the hottest running Athlons). IBM's Power4 chips also pump out huge amounts of heat, so relative to these competitors chips, AMD's Opteron could be a fairly low-power solution.

AMD's New Opteron Chips
Are Tapped for Red Storm
By DON CLARK
Staff Reporter of THE WALL STREET JOURNAL
Endorsing the technology of one of Intel Corp.'s key rivals, Sandia National Laboratories and Cray Inc. plan to build a massive supercomputer using a soon-to-be-introduced line of microprocessor chips from Advanced Micro Devices Inc.
The development project, estimated in June to cost $90 million, is a high-profile vote of confidence for AMD's new Opteron chip, in a small but prestigious market long dominated by other chip suppliers. It represents a missed opportunity for Intel, which has been targeting its new Itanium line at high-performance computing applications.
Red Storm, Sandia's name for the new supercomputer, also marks a step forward for the U.S. effort at leadership in supercomputers, which suffered a blow this year with the completion of a huge machine called the Earth Simulator by Japanese government agencies and NEC Corp. Where recent U.S. machines have largely been constructed out of components used in commercial computers, Cray is expected to develop special technology for connecting the AMD chips that should make Red Storm suited for more-complex scientific problems.
"This is a move away from commodity components," said Horst Simon, division director of the National Energy Research Scientific Computing Center, a supercomputer facility affiliated with Lawrence Berkeley National Laboratory. "It's very exciting."
Sandia, which does research for the U.S. Department of Energy in Albuquerque, N.M., and Livermore, Calif., has a performance goal of 100 trillion operations per second for Red Storm. It hasn't disclosed most technical details, including the chip selection. But Mr. Simon estimated that the machine will require 16,000 or more microprocessors to hit its speed target, which would appear to surpass the Earth Simulator's current performance.
Sandia said in June that it had selected Cray, a longtime supercomputer maker based in Seattle, to negotiate a development contract. Cray and Sandia officials didn't return calls seeking comment Friday. AMD and Intel officials declined to comment.
AMD could use some good news. The company's Athlon chip line, mainly used in personal computers, has been falling behind the performance of comparable Intel chips. The company reported last week a third-quarter loss of $254 million on sales of $508.2 million, off 34% from the year-earlier period.
Opteron is a high-end member of the new line, code-named Hammer, that is due out next year and viewed by analysts as AMD's best hope for recovery. Like the Itanium, Hammer chips are designed to process 64 bits of information at a time, instead of 32 bits, a capability that helps run huge databases and solve scientific problems.
Intel's Itanium line, developed over eight years with help from Hewlett-Packard Co., is based on an entirely new architecture and achieves its best performance on new 64-bit programs. AMD, by contrast, made 64-bit additions to the original Intel technology used in the past by both companies.
The difference, AMD says, allows Hammer-based computers to run both 32-bit and 64-bit software at high speed. AMD released preliminary test results last week for Opteron -- so far not validated by outside researchers -- that show the chip exceeding Intel's latest Itanium 2 model on one of two widely-used speed measures, AMD said.
Itanium 2, introduced last summer, has already been selected for at least a half-dozen high-performance installations. The Pacific Northwest National Laboratory, another Department of Energy facility, is building a $24.5 million system based on 1,400 Itanium 2 chips. Based on past Sandia announcements, the Red Storm project's stated performance goal is more than 10 times that of the Pacific Northwest project.

Even high-end UNIXs like Sun's Solaris don't commercially scale much beyond 100+/- cpus, and are generally intended for UMA, not NUMA.
When you step away from standard SMP systems into parallel and NUMA architectures, there are lots of problems to solve that don't exist at the small end of the scale, both at the OS and the app level. OSes better suited to that environment already exist (anyone have more info ???).

Let's say that they use 2000 8-way Opteron boxes. Thus each kernel will run over 8 processors, with MPI performing message passing between boxes. That's how it works on ASCI White etc anyhow (except they run AIX on POWER3 processors).
It would be quite an acomplishment to implement a NUMA architecture over 16000 processors. SGI can get decent performance with 128 processors (supposedly 512 but I have not used this), and I think Cray's T3E-1350 supports NUMA on up to 2176 processors. Cray is known for great interconnects though -- they can do it if anyone can.
