I agree with what others have said Grid Computing is distinct from other forms of distributed computing.
Check out OGSA [globus.org] - the Open Grid Services Architecture - and learn what is and is not a Grid. This is the de facto standard for building Grids.
Even new products that are *sold* with Grid in their title aren't necessarly THE GRID though they might be A GRID.

Traditional grid computing stemmed from the science community which had specific needs to both collaborate across heterogeneous administrative domains, and to process increasingly large amounts of data (often at a budget). This vision has been increased to incorporate the ultimate goal of distributed computing, in which total global processing, storage, and computing resources in general can be seen as effectively a single entity. The problems in addressing this are huge and a major focus of software research. Grid computing systems as they are today tend to be only usable by relative experts, and it is still sometime before the average user will find themselves able to regularly harness such power - something which must happen before widespread use. Supporting such complexity requires increasing automation in the self-management of systems, which requires better representation of data and processes in terms of semantics. Ultimately the future of the web and grid computing are likely to collide into what some term as "ubiquitous computing". See www.semanticgrid.org for some more info.

Apple QMaster, XGrid (Score:2)

Like I've been saying for quite a while, Apple finally announced that all their Pro AV products will support distributed processing with QMaster. Currently Shake, Compressor, and Maya are supported, soon Final Cut Pro support will be added. Everyone will go nuts once they see the performance of FCP with distributed processing.
And then there's XGrid, designed for cooperative processing in scientific tasks. I haven't used it so I can't judge its utility.
Yep, Apple is leading the way with this sort of Grid Computing software. This is what you can do with a bit of your own proprietary software built on top of Open Source unix. And I don't see any reason why people couldn't extend QMaster and XGrid support to other platforms, creating a compatible OSS version.

Did you forget to mention distributed.net ?
They have been doing this for years ... OGR, DES, RC5, CSC ... dare I say the biggest one ever, except for the ueber-d.net-geeks who had to choose SETI. :)

I expect that fairly soon there will be an efficient market for CPU cycles. That might help to offset the cost of a new machine, but it will also probably have the effect of killing off the donation-based projects like SETI@home.
Is there really a need for a majority of those spare CPU cycles? Or is there more computing power than can reasonably be used for the types of problems that can be distributed to home and educational PCs?
It doesn't take much creativity to think of ways you could use up ridiculously large amounts of cpu power. In the relatively near future, I can imagine:
spammers paying people to compute hashcash postage
online gamers paying for rendering of Pixar-quality animation
For the more distant future, a lot of really difficult AI problems might become more tractable if you could throw enough CPU power at them. Neurobiologists can already simulate the nervous systems of very simply organisms; maybe at some point it will become possible to simulate a human brain directly.

Spare cycles no longer exist.... (Score:3, Insightful)

Most modern CPUs no longer "waste" spare CPU cycles like they once did.
If your CPU runs at 100%, you are using more power and therefore makes your electric bill increase. Therefore, when you run distributed applications, you are actually paying $$$ for what you are giving away.
In recent history, laptop CPUs have started throttling themselves and using even less power, and desktop CPUs will start doing the same before long.
Not that this has that much to do with grid computing...
Grid computings goal is usually greater utilization of your own resources...distriuted computing usually utilizes someone elses resources. :-) (I know, true and not true at the same time)

zoglmannk asked:
What is needed to bring grid computing to the masses? More education, advertisement, prizes, reimbursement?
Grid computing is not aimed at "the masses". Most of the research [computer.org] is concentrating on building systems for solving problems which normal people have no interest in.
That's not to say that we plebs won't benefit from a "cure for X" or "lower oil prices due to better flow models within pipelines" or even "more efficient cars desgined in simulated air tunnels"; we are just very unlikely to be the imediate user of the computing power.
always had this question about clusters... (Score:2)

so maybe someone will enlighten me.
If you build a cluster, among other things, you pay premium for:
high density server components;
major cooling and power.
Now if I use gigabit for the transport, can't I just distribute my boxes throughout the building so they can breathe easily? |
