Abstract
Parallel programming uses threads to enable multiple operations to proceed simultaneously. The entire concept of parallel programming centers on the design, development, and deployment of threads within an application and the coordination between threads and their respective operations. This article examines how to break up programming tasks into [...]

There are several aspects of software reliability. One aspect for example can be detected by the compiler by doing simple type checking. On the complete opposite side there is business logic and its faults. This is what we really want to focus on.
Business logic is the hardest part to debug and verify. The [...]

Universal Parallel Computing Research Center (UPCRC) at the University of Illinois has issued a first release of Deterministic Parallel Java (DPJ), a computer programming language that it is claimed can provide enhanced support for parallelism on multicore processors while at the same time supporting popular programming styles such as objected-orientation.
UPCRC is research collaboration between several [...]

The DARPA High Productivity Computing Systems (HPCS) program sought a tenfold productivity improvement in trans-petaflop systems for high-performance computing (HPC). This article describes programmability studies undertaken by Sun Microsystems in its HPCS participation. These studies were distinct from Sun’s ongoing development of a new HPC programming language (Fortress) and the company’s broader HPCS [...]

In industry surveys, more than 80% of embedded systems software developers report using either C or C++ as their primary programming language. Yet as a group, they earned a failing grade on a multiple-choice evaluation of their firmware-related C knowledge.
In December of 2007, an Embedded C Quiz was launched online as part of a redesigned [...]

Libraries play an important role in threading software to run faster on Intel multi-core platforms.
Multi-core platforms are the default computer platforms sold throughout the world. On a multi-core platform there are multiple processors contained on a single chip. That is, each chip has multiple cores that are each [...]

In the basic sequential model of programming, a computer program’s instructions are executed one at a time. Each task is performed in a specified order, and each task stands in line and must wait its turn.
This changes when the software requirements include multithreading or multiprocessing components. When parallel processing is called [...]
