Component-based software-engineering and software architecture gain importance in software engineering. It is a well known fact that high level architectures and modular composition help constructing large-scale software systems. Today, programming languages support software architecture insufficiently. This leads to a number of problems, e.g. reduced reusability and architectural erosion. In t...

The current OpenMP 2.5 specification does not include a binding for the Java programming language. However, Java is a wide-spread programming language that is even used for HPC programming. We propose an adaptation of OpenMP to Java by retrofitting the basic OpenMP directives to Java and further propose some new concepts to make OpenMP fit into Java’s language philosophy. We discuss how Java’s ...

A s mobile technology matures, handheld-device vendors are looking for ways to make their products more functional, and Java is one approach they are turning to. This is particularly the case with smart cellular phones, which are using Java to help add new capabilities. In smart phones, Java functions as a layer between the operating system and the hardware, or runs parallel to the OS within a ...

Cryptosporidiosis is a cosmopolitan parasitosis that affects a wide range of hosts including birds. As information concerning Cryptosporidium in birds is limited, the present study examined the prevalence and genotypes of Cryptosporidium in Java sparrows in Beijing and Shangqiu, northern China. Three hundred and fifty fecal samples were collected from Java sparrows (Lonchura oryzivora, 225 whit...

Java bytecodes can be executed with the following three methods: a Java interpretor running on a particular machine interprets bytecodes; a Just-In-Time (JIT) compiler translates bytecodes to the native primitives of the particular machine and the machine executes the translated codes; and a Java processor executes bytecodes directly. The first two methods require no special hardware support fo...

This dissertation presents several techniques to accelerate Java locks based on the analyses of their behavior from various viewpoints. Ten years have passed since Java was announced, and now the language has come to be used in various fields including large-scale Web services. To make such applications practical, performance improvements for the Java execution environments are indispensable. I...

The Marmot system is a research platform for studying the implementation of high level programming languages. It currently comprises an optimizing native-code compiler, runtime system, and libraries for a large subset of Java. Marmot integrates well-known representation, optimization, code generation, and runtime techniques with a few Java-specific features to achieve competitive performance. T...

We provide non-operational characterizations of Java memory consistency model (Java Consistency, or simply Java). The work is based on the operational definition of the Java memory consistency as given in the Java Language Specification [6]. We study the relation of Java memory behavior to that of some well known models, proving that Java is incomparable with PRAM Consistency and with both vari...

Execution behavior of a Java application can be nondeterministic due to concurrent threads of execution, thread scheduling, and variable network delays. This nondeterminism in Java makes the understanding and debugging of multi-threaded distributed Java applications a difficult and a laborious process. It is well accepted that providing deterministic replay of application execution is a key ste...
