Architecture




The Lattice Project is a hybrid of current archetypal Grid technologies and custom components. One Grid model is based on a conventional cluster where nodes receive work pushed by a master node. This model has benefited from substantial work on developing protocols for handling job management, file access, and security. For these reasons, the Globus Toolkit is the backbone of our Grid system. It provides an open source implementation of a number of these Grid protocols and services. Our system currently uses the Grid Resource Allocation and Management (GRAM) service, the Grid Security Infrastructure (GSI), and the Monitoring and Discovery Service (MDS), to name a few.

Another approach to Grid computing is the Desktop Grid (DGrid), in which idle cycles are scavenged from a large number of heterogeneous, distributed resources and used to execute large-scale, highly parallel scientific computation. One of the earliest such projects to be launched was SETI@home, which continues to use the processing power of large numbers of machines in its search for extraterrestrial intelligence. The dominant architecture for a DGrid consists of a coordinating server that distributes and tracks tasks over a large collection of potentially unreliable and untrusted machines. We are using the Berkeley Open Infrastructure for Network Computing, or BOINC, for integrating desktop machines into our Grid.

Condor software serves a number of functions in our Grid, most importantly as a queueing system and job scheduler. We are also making extensive use of Condor-G. Condor-G is the marriage of technologies from the Condor project and the Globus project. We are using its matchmaking facilities to pair jobs with suitable resources.

This architectural diagram provides a simplified overview.

So long Paul, it has been a hell of a ride.

Park your ego's, fire up the computers, Science YES, Credits No.

I guess I can't find the alleged slight....

I'm unreliable, and Untrusted, that's why the mentioned the "highly parallel scientific computation." so they could overcome our unreliability, and such.

Oooohh *rofl* come on, it's true. :)

It is one of the technical basics of Public Resource Computing that the hosts are potentially unreliable and untrustet because of overclocking, cheating, Microsoft Windows and a unpredictable amount of hard and software configurations. That's why BOINC must crunche a WU multiple times and validates the results.

But I agree that it is possible to understand it wrong. ;)

"Condor software serves a number of functions in our Grid"

Isn't Condor the name that the government gave to it's snoop program that was going to spy on everyone, and maybe doing so at this very moment?

The dominant architechture is a whole bunch of computers that have been made available to the project because the owner wanted to.

The machines are a chaotic mish-mash of this and that. Windows 95 to Solaris. Old Pentium's at 90 MHz and multi-processor PowerPCs and high-end servers and old, semi-retired laptops.

They can be withdrawn at a whim.

I think they were being nice.

No, that name was "Carnivore".

But they've changed it now, to something that sounds more innocuous.

The good news is that it apparently does not work ... I saw a mention of that in one of the enginerring magazines I read ...

Yeah... They outsourced the whole "monitoring your email" to outside private agencies.

(unconfirmed, but still plausible and possible)

wonder if there is a way to take down the email thing. rather brazen of the us goverment. if my friend in dubai (UAE) were to send me a e-mail and they thought it was bad would she be punishable. sorta like when some how websites are shut down for viloation of some US law when they are from Brazil or something.

ORDERING PIZZA IN 2008

This is so close to what is probably going to be happening in 2008 that I’m not sure how funny this really is...

Operator: Thank you for calling Pizza Hut. May I have your national ID number?

Customer: Hi, I'd like to place an order.

Operator: I must have your NIDN first, sir.

Customer: My National ID Number, yeah, hold on, eh, it's 6102049998-45-54610.

Operator: Thank you Mr. Sheehan. I see you live at1742 Meadowland Drive, and the phone number is 494-2366. Your office number over at Lincoln Insurance is 745-2302 and your cell number is 266-2566. Email address is M_Sheehan@home.net. Which number are you calling from sir?

Customer: Huh? I'm at home. Where'd you get all this information?

Operator: We're wired into the HSS, sir.

Customer: The HSS, what is that?

Operator: We're wired into the Homeland Security System, sir. This will only add only 15 seconds to your ordering time.

Customer: (sighs) Oh well, I'd like to order a couple of your All-Meat Special pizzas.

Operator: I don't think that's a good idea, sir.

Customer: Whaddya mean?

Operator: Sir, your medical records and commode sensors indicate that you've got very high blood pressure and extremely high cholesterol. Your National Health Care provider won't allow such an unhealthy choice.

Customer: What?!?! What do you recommend, then?

Operator: You might try our low-fat Soybean Pizza. I'm sure you'll like it.

Customer: What makes you think I'd like something like that?

Operator: Well, you checked out 'Gourmet Soybean Recipes' from your local Library last week, sir. That's why I made the suggestion.

Customer: All right, all right. Give me two family sized ones, then

Operator: That should be plenty for you, your wife and your four kids. Your 2 dogs can finish the crusts, sir. Your total is $49.99.

Customer: Lemme give you my credit card number.

Operator: I'm sorry sir, but I'm afraid you'll have to pay in cash. Your credit card balance is over its limit.

Customer: I'll run over to the ATM and get some cash before your driver gets here.

Operator: That won't work either, sir. Your checking account is overdrawn also.

Customer: Never mind! Just send the pizzas. I'll have the cash ready. How long will it take?

Operator: We're running a little behind, sir. It'll be about 45 minutes, sir. If you're in a hurry you might want to pick'em up while you're out getting the cash, but then, carrying pizzas on a motorcycle can be a little awkward.

Customer: Wait! How do you know I ride a scooter?

Operator: It says here you're in arrears on your car payments, so your car got repo'ed. But your Harley's paid for and you just filled the tank yesterday.

Customer: Well, I'll be a #%#^^&$%^$@#

Operator: I'd advise watching your language, sir. You've already got a July 4, 2003, conviction for cussing out a cop and another one I see here in September for contempt at your hearing for cussing at a judge Oh yes, I see here that you just got out from a 90 day stay in the State Correctional Facility. Is this your first pizza since your return to society?

Customer: (speechless)

Operator: Will there be anything else, sir?

Customer: Yes, I have a coupon for a free 2 liter of Coke.

Operator: I'm sorry sir, but our ad's exclusionary clause prevents us from offering free soda to diabetics. The New Constitution prohibits this. Thank you for calling Pizza Hut.

The way things are going i would not be surprised if this actually happens :(
