Observations
Software architecture is THE bottleneck
Too many systems rely on Moore's law to solve scaling and performance problems
Use of Excel considered harmful(except at presentation layer)

What Does Grid Computing Mean?
It describes a state of being, not an activity. Imparting meaning to the phrase requires a clear specification of the processes involved.
Service Oriented Architecture(SOA) emerges from the fog of jargon

The backbone of continuously available services that emerges is "THE GRID"

Our Jini Technology Implementation
Master /Worker pattern
Bootstrapping
GridApps
Worklets and a Worklet Container
Single sign-on
GridManager
Administrator

Master putting together set of tasks to be done, puts it in the javaspace, worker then calculates the answer and puts it back in the javaspace.

Tuple space-based approach known to jini Koolaid drinkers as standard pattern
First thing in all the books seems quite intuitive pretty much where we started
Things that get left out of the books
Security
Management/monitoring
Reliability
Deployment/multi-purposing of the grid

Deutsch's 8 Fallacies
1. The network is reliable
2. Latency is zero
3. Bandwidth is infinite
4. The network is secure
5. Topology doesn't change
6. There is one administrator
7. Transport cost is zero
8. The network is homogeneous

The Future: Federation No single points of failure
