Portal and Workflow in Grid Computing: From Application Integration to Service Integration - Grid Computing: Infrastructure, Service, and Applications - page 295

In the section of service integration by workl ow, the following topics
are covered: (1) workl ow technologies were introduced, which include
service-oriented workl ow, workl ow languages, workl ow engines, and
workl ow systems; (2) features of scientii c workl ow in grid computing
were identii ed; and (3) the state-of-art service component architecture
(SCA) that can be employed to build a service-oriented workl ow
was described.
In the case study, the literature related to the UK e-Science program was
reviewed, and a MaterialsGrid project that employs both portal and work-
l ow technologies to provide an integrated platform and to automate the
operations required for running CASTEP quantum mechanical simula-
tion over grids was introduced.
