A major challenge in grid computing remains the application software 
development for this new kind of infrastructure. Grid application programmers 
have to take into account several complicated aspects: distribution of data and 
computations, parallel computations on different sites and processors, 
heterogeneity of the involved computers, load balancing, etc. Grid programmers 
thus demand novel programming methodologies that abstract over such technical 
details while preserving the beneficial features of modern grid middleware.

For this purpose, the authors introduce Higher-Order Components (HOCs). HOCs 
implement generic parallel/distributed processing patterns, together with the 
required middleware support, and they are offered to users via a high-level 
service interface. Users only have to provide the application-specific pieces 
of their programs as parameters, while low-level implementation details, such 
as the transfer of data across the grid, are handled by the HOCs. HOCs were 
developed within the CoreGRID European Network of Excellence and have become an 
optional extension of the popular Globus middleware. The book provides the 
reader with hands-on experience, describing a broad collection of example 
applications from various fields of science and engineering, including biology, 
physics, etc. The Java code for these examples is provided online, 
complementing the book. The expected application performance is studied and 
reported for extensive performance experiments on different testbeds, including 
grids with worldwide distribution.

The book is targeted at graduate students, advanced professionals, and 
researchers in both academia and industry. Readers can raise their level of 
knowledge about methodologies for programming contemporary parallel and 
distributed systems, and, furthermore, they can gain practical experience in 
using distributed software. Practical examples show how the complementary 
online material can easily be adopted in various new projects.
