Last I spoke with AMD (which was about 6 weeks ago, and I work for an AMD server vendor) the 8 way HT interconnect Opteron chips will require Socket F. In those chips each Opteron can connect to 7 others, I'm NOT talking about 4 - Dual Core Opterons which is an 8 way server, we have those already. Socket F is complete, in the bag but for some reason AMD has yet to give the offical go ahead for us to take orders.
Given the way AMD is going you by 2008 you will get a 64way server with 8-8 core CPUs all interconnected via the HyperTransport bus and in a 4U form factor, and at a lot lower price point than current 64 way systems.
Good point, I mean 4P = 4 sockets, either 4 way or 8 way with Dual Cores.
If you take a look at the AMD Architecture vs the Intel, AMD uses HyperTransport to connect virtually everything direct to CPU and Intel still has the NorthBridge (and SouthBridge) chips to do that same interconnection. The only way Intel is beating AMD with the new chips is with the 65nm process allowing a faster FSB. A smaller chip also pulls less current and thus makes less heat even with the faster bus. When AMD goes to 65nm the lead will swap back, and considering that anything smaller than 65nm is still in the R&D labs AMD might have that lead a long time.
Based on the opinion of most IT analysts, the 4P servers is actually the "sweet spot" of the market. So I expect Opteron to continue it's lead there. The HyperTransport from AMD is superior to the FSB when you start getting into multiprocessor servers. And I expect AMD will extend HT to be up to 8 chips (currently 4) in the next generation chips sometime in 2007.
Sun has heavily invested in Xen, and I wouldn't be surprised to see them BUY Xen. Then Xen technology is in the next release of Solaris. Solaris 10 is RH's #1 competitor at the Enterprise OS level (and beats it in many ways). So if they can throw out some FUD and screw up Sun they are going to do it. After all they learned from what MS has done to Linux and how well that worked. Right now, TODAY, if I had to do virtualization I chose VMWare or Solaris 10 using Containers.
The growth in power and influence of the gov't in our lives has increased tenfold the last few decades. There's precious little we can do.
BULLSH*T.
In a Representative Republic (the USA is NOT a Democracy) the People hold the power, the Congress only votes the will of the people. Congress has granted itself powers that it really does not have a Constitutional basis for, that is where BIG Government has come from. And we certainly CAN do something about it that misuse of OUR power. We have three boxes, the soapbox, the ballot box and the ammo box with which to do something. Of course the last box is truly the last resort. I also think that is why the Founding Fathers gave us the right to keep and bear arms, so we COULD use Box #3 against a tyrranical Government (no GWB is NOT a Tyrant as much as the uneducated on/. think he is) if nothing else worked.
If you are going to TEACH Government, teach it ALL not just the Libertarian angle. Teachers are held to a much higher standard of knowledge and truthfulness (rightly so). Let the kids decide based on the FACTS not the Politics.
IRAN not Iraq unless you meant when Saddam was in power. If things continue on the present path I'd say Iran will have small nukes in 5 yrs, maybe less.
Wow, 9/11 wasn't a violent time that tore the world apart? The London Subway bombings as well. What rock have you been hiding under? Is this Osama posting from his cave in Pakistan??? If so, hopefully the CIA is reading what you wrote, backtracking your IP address and sending some visitors.
You really have no clue what you are talking about. It's NOT at all about religion. It's not about Western democracy because democracy simply means the people get to chose (if they chose B over A they got to live with that). And I know it's not "secular" (which means to put Man above God) so where the heck you get the morals angle from I don't know.
Go away, son, you bother me as your arguments are confused and pointless.
You assume 1 core per chip, it's quite possible that they have several cores per chip. Chips with 4 cores are now common, 8's on the horizon and 16's in the lab. Each CPU was special built for astrophysics calculations (not sure what that means..seems to me just to be lots of floating point) by Hitachi which absorbed the cost of the CPU development. Also, the chips may be able to work somewhat in parallel if the software is written that way which obviously will increase performance. So, I don't doubt the figures, I think they have just come up with a novel approach. Which, if you RTFA is exactly what the Architect of BlueGene had to say.
Two come to mind really quick, Lincoln and FDR. Compared to some of the things they got passed what we have now is trivial. We just have better means to enforce the laws and to complain about said enforcement. The laws come with the times, we really ARE in a WAR on Terror, if you don't think the Islamic Radicals want to eliminate the concepts of Western society you have your head in the sand. There are really just as bad as the Nazi's were, Hitler wanted to rid the world of the Jews, the Islamo-Nazis want to rid the world of Christians AND Jews. Lincoln and FDR imposed some drastic rules as well and the USA didn't collapse.
But because Microsoft is already big and Windows is all over the place and people are already using it, they can't be allowed to do this. That about sums it up?
No, because they are under DOJ orders to allow other folks software to INTEROPERATE. What they are doing will make software from folks like Anti-Virus and Spyware unable to do that, just like back in the days ( you ARE old enough to recall the 1990's right?) of the Netscape vs IE issues. When you hold an incredibly dominating position in the market the law only allows you to do certain things, things that allow you to keep and build your market position by mechanisms that "lock-out" others is definately not allowed. Read up on Anti-Trust laws before running off about it.
If they do that then we are back to the same issues that got them in trouble with IE. AND they would be violating the Anti-Trust settlement with the DOJ. Only MS having the ability to write software that operates at the highest privelege level is a monopolistic practice. Then again it may force more people to Linux and the *NIXs of the world which could be good. Don't give me the typical stupid/. reply of there being a Republican in the White House and thus it doesn't matter what M$ does. It matters a great deal, as there are a lot of very important and secure applications that run under Windows, and we all know how good M$ security is in their software. I surely don't want the same team that brought me the security holes being the only ones able to fix the holes (assuming they decide they are in fact holes and just not an imginary hole).
AMD has some ideas about direct attached cards for the Hyperchannel but that's not making a lot of progress, the big Opteron server vendors like Sun & HP are not getting behind it. When we get cards we can develop drivers. Right now it all goes thru a PCI Bridge which actually slows things down.
The RTOS doesn't use a lot of cache, It needs a fast CPU and tight code to handle the massive numbers of context switches.
The code you mentioned isn't all running on a CPU either. A lot of it is on custom hardware to keep up those data rates. The PCI-X bus would work except very high end, and it IS available in current 1U servers from people like Sun and HP, but certainly not in that old 286 in the closet. You could turn an Opteron with the HyperChannel architecture into a pretty darn good router. But the Opterons cost quite a bit more than a 286 would (does any foundry still MAKE 286 chips?). It's a good project but I agree it's not ready for prime time in the corporate data center.
Funny as hell but I know a lot of retirees that would love bigger and longer pensions. Don't tell the spammers this idea or we'll get a whole new set of Spam. They'll just change a few letters and bypass the filters.
LIQUID Gasoline is NON-FLAMMABLE. However Gasoline VAPORS mixed with air are highly flammable. As long as your fuel tank does not rupture (recall the exploding Pintos and Chevy Pickups?) you are OK. It takes a hell of a rear-ender to rupture your tank and if cars used bladders inside the tanks like race cars you'd never see a fire. However, the laptop batteries are documented to explode sort of at random, and if one goes the others may go with. Also, if you can afford 80K for a car you can pay the $3-$4 a gallon to drive anything you want, the car is a "look at me, aren't I Green" statement nothing more. Or maybe "I'm so f*cking rich I can drive an 80K electric car". Until they can produce them for 20K and they last 200K miles and have a low operating cost they are not going to catch on enough to make any difference in consumption of "petroleum distillates".
Wow, someone else who wrote code for an old Intel 8051C Microcontroller! I also wrote code for this animal in PL/M in the early 90's. It was a very versatile chip for it's day. We ran all the radio traffic in an airplane with one of these, and added in a TI C30 DSP to add warning tones for altitude, etc. High tech for it's day but we have kids toys with more CPU power these days. Does remembering the 90's make us "Antique Geeks" ?
Zero downtime is very difficult to acheive without some very eloborate setups. What do you do when you need to patch VMWare or the Virtual OSes? Do you have a cluster where you can take down one machine at a time?
The problem may not be VMWare, it could be the Win2003 virtual servers. Win2003 is a resource hog and virtulizing to put multiple instances with each doing lots of work isn't going to work well. Sounds like you really need to consider moving to Java and Solaris 10 Containers which you can setup to limit resource usage so one run away process/server does not kill the box. I know that's a rewrite of you app but it's probably a better long term solution which means your PHB will never go for it!
yea right, M$ is going to allow anyone to look at the SOURCE code to validate it. They wouldn't even let NASA look, or the military. Considering how M$ is in trouble with the EU about documenting how Windows works I wonder if someone in the EU Government might try and block this deal to be "exclusive".
Hell of a difference in turning on the "Check Engine Soon" light and monitoring the systems of a passenger car engine at 3-4K RPM and doing all of the things needed for a racing engine at 15K RPM for the duration of an F-1 race and not miss a thing. A race engine needs a hard realtime system, where if you don't do something NOW there are failure consequences. Tell the transmission to downshift to 3rd when you really meant shift up to 5th and you just blew up a very expensive engine and fell out of a very critical race. Not too good!

Exactly, and Interrupts cause context switches. The AC was wrong.

The AMD HyperChannel architecture has some possibilities. Non-disclosure prevents me from saying more.
