A Three-Way AMD Opteron Server

Abdul tips a thin little review up at The Inquirer of the Themis Slice. "The Slice is a three socket Opteron machine with two PCIe slots and two Infiniband 4x ports... Why would you want three sockets rather than four? Easy, latency. Any CPU in a 3S system is one hop away from any other CPU. In a 4S system, you can be two hops away. This adds latency, and more importantly, you take a big hit on cache coherency latency. This kills performance."

What is this article about?

Sorry... I tuned out after 'A Three-Way'.

What would you do...

...with a million dollars?

Lawrence: Three chips at the same time, man.
Peter: That's it? If you had a million dollars, you'd use three sockets at the same time?
Lawrence: Damn straight. I always wanted to do that, man. And I think if I worked at AMD I could hook that up, too; 'cause I hate motherboard layouts with latency.
Peter: Well, not all layouts.
Lawrence: Well, the type of chips that'd triple up on a board like that would.
Peter: Good point.
Lawrence: Well, what about you now? what would you do?
Peter: Besides three chips at the same time?
Lawrence: Well, yeah.
Peter: Idle.
Lawrence: Idle, huh? Peter: I would relax... I would sit on my ass all day... I would idle.
Lawrence: Well, you don't need a million dollars to idle, man. Take a look at that fourth chip: it's two hops away, don't do shit.

Mac OS X on this machine...

Any CPU in a 3S system is one hop away from any other CPU.

So... if I run Mac OS X on this box, can we call it an iHOP?

Threesome

So what kind of doe will this Opteron Threesome run me?

Probably a couple of bucks at least!

Only if you use it to fry pancakes!

hard to justify

[aapold]

I mean how to convince the wife that we need a three-way?

Re:hard to justify

[swb]

Especially when you haven't shown her the value in a two-way yet.

No.

The plural of 'die' is not 'dice'.

Let's get the basics straightened out before you resume pretending you know anything.
