Title: Service Oriented Approach to High Performance Scientific Computing
	(Thesis Proposal Review Seminar)

Abstract:

 The Service Oriented Approach (SOA) has been embraced in grid and high
 performance computing for several years for its trademark
 characteristics of data interoperability, fault tolerance and
 scalability. It has worked well for high performance financial
 applications. However, little effort has been made to make it effective
 with scientific applications, especially with medium to fine grained and
 communication intensive applications. This is because, unlike the
 financial solutions, the end tasks (final atomic unit of work) of these
 applications are very much inter-dependent. Interdependency of tasks
 affect the granularity of tasks, which is beyond the control of
 programmer or grid middleware. That is, tasks can become too small to be
 effectively processed in a distributed environment for the associated
 costs along with the tasks - startup cost and the communication cost -
 may outperform the computational advantages in distributing the work in
 SOA model. In order to make SOA model work well for scientific
 applications, we have to decouple fine granularity of tasks in those
 applications from its associated costs. This Phd research suggests a
 Data Service around the Service and Management nodes of SOA middleware
 towards this end. This Data Service would suggest a local memory space
 and a global addressing system that is distributed among compute nodes
 to support updating of data-service objects.
