Two critical forces are shaping the direction of software development. One
is the deep adoption of parallel computing. The other is the move
toward Service Oriented Architecture. The current technologies of chip multiprocessor
(CMP) and chip multithreading (CMT) processor design, horizontal-scaled systems,
near zero latency interconnects, and new web service standards all accelerate
both forces into reality and adoption everywhere. It is quite easy to predict
that most desktop machines or even laptops will be powered by multi-core or
CMT processors over next few years. But how prepared are the software developers
and tool vendors for the challenge of working in parallel
computing environments?
The scientific and engineering communities adopted parallel computing
to solve their large scale complex problems a long time ago. But parallel
programming development has always been quite challenging, even for advanced
black-belt developers. This also raises more difficult issues of productivity,
scalability and reliability. The challenges of parallel computing are not new
to Sun. With the Sun
Studio software, the developer has a complete set of tools and an
integrated environment for high performance parallel computing.

OpenMP - Shared Memory Programming Model
|
- OpenMP.org
Website
The OpenMP Application Program Interface (API) supports multi-platform shared-memory parallel programming in C/C++ and Fortran on all architectures, including Unix platforms and Windows NT platforms. Jointly defined by a group of major computer hardware and software vendors, OpenMP is a portable, scalable model that gives shared-memory parallel programmers a simple and flexible interface for developing parallel applications for platforms ranging from the desktop to the supercomputer.
