| Metacomputer is same as a computational grid |
| I will describe NPAC projects somewhat tomorrow |
Web based Metacomputing has two related manifestations
|
This can be extended to using metacomputing technology (hardware and software) as basis of parallel computing software
|
| 15 or so years ago parallel computing had a clear application driver for increased performance |
| Is metacomputing user or technology driven? |

| What is the application drivers for metacomputing and is high performance necessary? |
| Essentially all applications will use some sort of computational grid but only some ( a very small fraction?) will use high performance |
Most High Performance grids will come from scaling "ordinary grids" which will use commodity solutions.
|
"High Performance" can come from several sources

| "Big Queue in the Sky" -- seamless (one at a time) access to multiple heterogeneous supercomputers |
| Collaborative access to specialized scientific instruments and visualization (a few linked systems) |
| "Parameter Studies" (pleasingly parallel -- no communication) |
| Application Integration (coarse grain components -- not particularly high performance) |
| PC, Workstation, Origin 2000/SP2 clusters (parallel computing built from distributed computing technology -- general application but network specialized) -- Grid in a Box |
| Distributed Modeling and Simulation (using geographically distributed computers to simulate geographically distributed systems) |
| TeleMedicine and Distance Education (high "performance" as large number of users) |

Industry: Hottest General Area in recent corporate enterprise Intranet conference (after electronic commerce) was "application integration" -- linking the "ᡛ" separate major (SAP, PeopleSoft ..) applications (in typical large corporation) into a "grid"
|
| (Industry) Engineering: There is classic multidisciplinary application in engineering design and manufacturing as in NASA's IPG (Information Power Grid) and ISE (Intelligent Synthesis Environment) |
