Many applications are what is called (essentially) embarrassingly or more kindly pleasingly parallel
|
These are made up of independent concurrent components
-
Each client independently accesses a Web Server
-
Each roll of a Monte Carlo dice (random number) is an independent sample
-
Each stock can be priced separately in a financial portfolio
-
Each transaction in a database is almost independent (a given account is locked but usually different accounts are accessed at same time)
-
Different parts of Seismic data can be processed independently
|
|
In contrast points in a finite difference grid (from a differential equation) canNOT be updated independently
|
|
Such problems are often formally data-parallel but can be handled much more easily -- like functional parallelism
