Re: [ogpx] the term 'grid'

[Infinity Linden <[e-mail]>]

thanks for bringing this up, dave.

the IBM developer support article you reference and other references
indicate that grid computing is "a form of distributed computing ...
composed of a cluster of networked loosely coupled computers acting in
concert to perform very large tasks." (i found that definition at the
wikipedia and another IBM developer facing document)

virtual worlds used for interoperability testing between Second Life
and OpenSimulator were implemented by.. "a cluster of networked,
loosely coupled computers acting in concert to perform a large task"
(that large task is the simulation of the virtual world.)

So the "grid" in Open Grid Protocol is accurate; it is a protocol
intended to be deployed on a grid.

confusing matters further, Oracle's developer support organization
defines "grid computing" to be largely similar to what IBM developer
support calls "cloud computing."

Krauter and Maheswaran in the proceedings of the 1st IEEE/ACM
International Workshop on Grid Compuing  defines "grid computing"
as... "a grid is a computing and data handling virtual system formed
by aggregating the diverse services provided by diverse resources to
synthesize problem solving environments." (
http://www.gridcomputing.org/grid2000/book/19710064.ps )

i'm not sure this rises to the definition of a "precise meaning."
instead, it seems like there is general agreement that "grid
computing" involves a loosely coupled collection of distributed hosts
working together on the same or related problems. this is a good
definition of the architecture we explicitly support with OGP.

also... historically... the term "grid" has been used among the OGP
interoperability investigators to define the collection of distributed
systems which implement the virtual world under simulation.
