We can distinguish Decomposition and Integration
|
|
Decomposition is performed by an HPF or other Parallelizing compiler; or by a user writing a Fortran + Message Passing code "by hand"
|
|
MPI integrates decomposed parts together with high bandwidth latency constraints
|
|
Systems such as AVS integrate larger modules together and much of "software engineering" (modular style of programming) involved with this
|
Web is a powerful integration model suitable for large coarse modules with modest latency and sometimes modest bandwidth requirements
-
naturally "integrate" data(bases), people, computation together
|
|
Collaboration, computational steering, multidisciplinary science are all integration and not decomposition problems!
