Fundamentals of puting
The purpose of this IBM Redpaper is to provide discussion material about puting,
concepts, use, and architecture. puting represents unlimited opportunities in terms
of business and technical aspects. The audience for this paper are all hungry minds looking
for a collection of facts and data about this new and exciting realm.
The following major topics will be introduced to the readers:
What puting can do
Grid concepts ponents
Grid construction
The present and the future
What the grid cannot do
puting, most simply stated, is puting taken to the next evolutionary
level. The goal is to create the illusion of a simple yet large and powerful self managing virtual
computer out of a large collection of connected heterogeneous systems sharing various
combinations of resources.
The standardization munications between heterogeneous systems created the
explosion. The emerging standardization for sharing resources, along with the availability of
higher bandwidth, are driving a possibly equally large evolutionary step in puting.
What puting can do
When you deploy a grid, it will be to meet a set of customer requirements. To better match
puting capabilities to those requirements, it is useful to keep in mind the reasons for
using puting. This section describes the most important capabilities of grid
computing.
Exploiting underutilized resources
The easiest use of puting is to run an existing application on a different machine. The
machine on which the application is normally run might be unusually busy due to an unusual
peak in activity. The job in question could be run on an idle machine elsewhere on the grid.

There are at least two prerequisites for this scenario. First, the application must be
executable remotely and without undue overhead. Second, the remote machine must meet
