anyone whos' got the 'share my compute cycles' checkbox set on their ipod2 automatically shares their ipod2's cpu cycles, again announced by rendezvous, with the rest of the system.
for the duration of that gig, the machines are all bound together, beowulf-style, to distribute the live recording of the event that is being produced for prosperity during the concert. some 'secrets and surprises' are thrown into the tracks too, just for grins.
at the end of the gig, everyone walks away with their own digital recording of the event, custom, unique, 'branded to the event'.
the whole thing was included in the price of admission, and open to anyone who walks into the concert arena with their boxes turned on
I can totally see this happening. In fact, if I had the resources, I'd start a company that does just this service for concerts and gigs and such

This is an old idea - it's called bootlegging, and with a few notable exceptions, almost all record labels oppose it.

Plus, they would get revenue from all the non-ipod owners as well, and could fix the parts where the vocalist sings out of tune.

Published: February 23, 2004
SAN FRANCISCO, Feb. 22 ? Some class science projects get out of hand.
That is certainly the case with Patrick Miller's graduate course in do-it-yourself supercomputing at the University of San Francisco. On April 3, his students plan to assemble the first "flash mob supercomputer" in the school gym.
While brainstorming about how to build a home-brew computer powerful enough to be added to a list of the world's 500 fastest computers, Mr. Miller and his students, along with Gregory D. Benson, an associate professor of computer science, came up with the idea of an electronic barn-raising. They decided to build on the concept of flash mobs, the sudden Internet-organized gatherings with no particular purpose that became an unlikely fad last summer.
Last week, the class put out a call for about 1,200 volunteers to bring their computers to the Koret Gym here for a day and plug them into a shared high-speed network.
"This is what happens when crazy ideas catch fire and people say, `Wait, there is nothing to stop this,' " said Mr. Miller, who is a lecturer at the university and a computer scientist at the Center for Applied Scientific Computing at the Lawrence Livermore National Laboratory.
There are already many Internet-connected virtual supercomputers, like the SETI@home project, which uses the spare computing cycles on the personal computers of volunteers to hunt for signs of alien civilizations. Several universities have shown that it is possible to hook hundreds of off-the-shelf personal computers together to create supercomputers. But until now no one has tried to build an instant supercomputer in one place.
"It struck me as being something of a 60's idea," said Dennis Allison, a founder of Dr. Dobbs, a Silicon Valley magazine for computer programmers. "This could easily be an idea from one of William Gibson's science-fiction novels, where everyone gathers in Grand Central station to save the world by plugging their machines into the Net."
Before stumbling onto the idea of the volunteer project, the class considered a variety of ways to make a cheap supercomputer, including buying many Microsoft Xbox game machines. However, the students would have needed to install the free Linux operating system on the machines to tie them together, and Microsoft has recently made that more difficult.
John Witchel, the graduate student who had the original idea of building a volunteer supercomputer, says he thinks flash mob computing will make it possible for high school students and community groups to harness computer power now available only to large corporations or government laboratories.
"We're trying to democratize supercomputing," Mr. Witchel said.
The group has high hopes for its gym machine. It plans to run a speed benchmark program known as Linpack. The group estimates that to make the next Top 500 list, scheduled to be released in June, the machine will need to reach a speed of about 550 gigaflops, or billions of mathematical operations per second. The No. 1 spot on the list is held by the Earth Simulator in Japan, which can run at more than 35 teraflops, or 35,000 gigaflops.
Jack Dongarra, a University of Tennessee computer scientist who helps maintain the Top 500 list, says the students have a shot at making the list, but it will not be easy.
"It could be that electrical power will be an issue," he said, adding that the slowest computer will limit the speed of the entire supercomputer. To make certain that they have enough speed, the students are asking that volunteers bring only computers with at least a 1.3-gigahertz Pentium or AMD processor and 256 megabytes of memory, requirements that most recent home machines will meet. Laptops are preferred because they use less power than desktop computers.
When all the machines are plugged together via donated high-speed networking switches, the students will be able to tack

You've either never been to a significantly large LAN party or are incredibly lucky. Getting x,000 randomly selected laptops to even all communicate together properly for the benchmark will be a major undertaking, nevermind doing any useful work in the amount of time allotted. The planners give the impression of being quite organized with their pre-made Knoppix disks but I assure you there will be something to gum up the works. This leads to a whole new discussion of why can't PC's be plug-n-go appliances after 20+ years, but nevermind that now...

Here is the deal... to use a hotspot you have to download a package that connects your computer to the local "grid". In exchange for network access the grid gets your spare CPU cycles. The best hotspots could leverage the power of hundreds of notebooks, and then resell this on the market as a computing resource commodity, for multiplayer games, data crunching, whatever.
Though... I'm running a high fever and this is perhaps the fruit of a deranged mind.

1200 laptops could be a big problem (Score:5, Insightful)
Now, let's generously assume that each laptop is drawing half an amp at 110 volts. At 1200 laptops, that's 600 amps. The circuit breakers in my house trip at 15 amps, but I'll generously assume this facility has 50 amp wall circuits. That would still require 12 entire circuits, plus a safety factor, nevermind all my generous back-of-envelope assumptions.
Okay, so assuming they've got a lot of extension cords, now we just have to deal with space. Let's assume, again, generously, that each person + computer + associated infrastructure needs only one square meter of floor space. This makes the space requirement equivalent to a 30m x 40m area, or about two World Cup soccer fields. I hope they've got one hell of a big gym.
Heat is, by comparison, a relatively minor issue. If the facility can handle a crowd that large, adding their low-power laptops is minor. People tend to dissipate about 100 watts anyway, so the laptops won't be the most significant source of difficulty.
It sounds like a very daunting task they have ahead of them. I hope they've already gotten these problems figured out, because this project sounds really cool.
Re:1200 laptops could be a big problem (Score:4, Informative)
600 amps is nothing for a place like this. I can get an 800 amp feed to my house, according to the nice folks at my local power company (and I'll be upgrading to that as part of my rewiring plan). 12 circuits is no big deal either. Think of the power requirements for holding concerts or any type of show, or just for lighting the place.
A place like that also probably has a house electrician on staff who knows the boards and how to get x amps from point A to point B. I doubt power is going to be the main issue holding them back on this.

And that was using specially tuned low latency ethernet drivers and TCP stack under linux.
These guys have very very little chance of doing anything useful at all - which is a bit of a pity, but perhaps if they did just a little research first..
I wonder if they even have network switches that will efficiently route 1200 nodes.. let alone a decent plan to interconnect them.
The first step would be to use 1Gbit or faster concentration to some very smart switches to at least cut down the network blockage a little.. It won't help with the terrible latency, but will give them a little headroom at some vector lengths.
They will also suffer terribly from the differing speeds of nodes - I've yet to see a solution for linpack that distributes efficiently over a wide speed range of machines.
Of course, I bet in the end they just come up with a great SETI score, or something similar - something that would actually scale at all on a cluster like this.
Oh well, I wish them luck anyway.

Interesting term "flash mob". The first time I encountered it was in the writing of sci-fi author, Larry Niven. In some of his series personal teleportation becomes ubiquitous giving rise to the 'flash mob'.
When a news broadcast reports a certain kind of story (riot, fire, etc) people start to teleport into watch the fun. The news reports the growing mob and before long it reaches critical mass and turns into a real riot as people take advantage by teleporting in and doing a quick bit of looting.
I'm not sure if Larry originated the term though ? Anyone know an ealier source ? Is it a 'real' phenomenon ?
