Problem Solving Environment Tools in the Linear System Analyzer
One research goal of the LSA is to provide a driving example
(or "point solution") for the creation, development, testing and validation
of tools for building problem solving environments (PSEs). This work is part of the
PSEware project ,
funded by the CISE directorate of the National Science Foundation, as grant
CCR-9527130. One of the major goals
of PSEware (as suggested by the name) is to provide not just PSEs, but
tools to help users construct their own PSEs. The key infrastructure
components of the LSA are
The PSE Manager, which provides services for starting and controlling
computational modules within the PSE. The PSE Manager is an HPC++
program using Nexus for communications between modules, and it
allows running modules on multiple machines across the network.
The Module Wrapper subsystem, which provides wrappers for computational
modules and handles communications with the PSE Manager.
The PSE Interface, which presents a generic framework for PSEs of the
pipeline of computational processes archetype.
A view of the generic architecture that the infrastructure tools target is:
