Simulation of Temporal Dependency on SwinDeW-G
Supervisor:Yun Yang (overall) & Jinjun Chen (day-to-day)
Suitable year level:3rd-5th year
Project Description
Grid computing is a new paradigm of distributed computing. It aims
to accommodate large-scale resource sharing in a dynamically negotiable
fashion across heterogeneous and autonomous systems. Grid computing has
become a hot topic internationally. A high degree of research interest
has been invoked. Industry efforts including those from Intel, HP,
Microsoft and etc. have also been made towards potential applications of
Grid computing. Many conferences, workshops and seminars are held annually
to boost the research and industry applications. One of the popular
organisations for Grid computing has been established to coordinate the
standardisation. That is OGF (Open Grid Forum).
SwinGrid (Swinburne Grid) is a grid platform being set up. SwinDeW-G
(Swinburne Decentralised Workflow for Grid) is a grid workflow management
system running on SwinGrid. SwinDeW-G is supposed to support large-scale
complex processes in complex scientific and business applications such as
climate modelling and international finance and banking analysis. Such
processes are defined as grid workflow specifications and executed in
SwinDeW-G by facilitating the computing and resource sharing power of
underlying grid infrastructure, i.e. SwinGrid.
Many grid workflows are often time constrained. Temporal constraints
are enforced and then verified to identify any temporal violations. Since
grid workflows are normally very complicated and could contain hundreds
of thousands of activites, a large number of temporal constraints are
often enforced. Multiple temporal constraints are dependent on each
other in terms of their verification effectiveness and efficiency
because later verification may make previous verification ineffective,
and later verification should utilise previous verification to save
current verification computation for better efficiency. We have
theoretically investigated temporal dependency between many temporal
constraints. This project aims to simulate our techniques in a real-world
grid workflow system (SwinDeW-G) on a real-world grid environment (SwinGrid).
The main objective is to reason about our theoretical results in experiments.
