JCUDA: A Programmer-Friendly Interface for Accelerating Java Programs with CUDA

Abstract: A recent trend in mainstream desktop systems is the use of general-purpose graphics processor units (GPGPUs) to obtain order-of-magnitude performance improvements. CUDA has emerged as a popular programming model for GPGPUs for use by C/C++ programmers. Given the widespread use of modern object-oriented languages with managed runtimes like Java and C#, it is natural to explore how CUDA-like capabilities can be made accessible to those programmers as well. In this paper, we present a programming interface called JCUDA that can be used by Java programmers to invoke CUDA kernels. Using this interface, programmers can write Java codes that directly call CUDA kernels, and delegate the responsibility of generating the Java-CUDA bridge codes and host-device data transfer calls to the compiler. Our preliminary performance results show that this interface can deliver significant performance improvements to Java programmers. For future work, we plan to use the JCUDA interface as a target language for supporting higher level parallel programming languages like X10 and Habanero-Java.

J-Orchestra: Enhancing Java programs with distribution capabilities

Abstract: J-Orchestra is a system that enhances centralized Java programs with distribution capabilities. Operating at the bytecode level, J-Orchestra transforms a centralized Java program (i.e., running on a single Java Virtual Machine (JVM)) into a distributed one (i.e., running across multiple JVMs). This transformation effectively separates distribution concerns from the core functionality of a program. J-Orchestra follows a semiautomatic transformation process. Through a GUI, the user selects program elements (at class granularity) and assigns them to network locations. Based on the user's input, the J-Orchestra backend automatically partitions the program through compiler-level techniques, without changes to the JVM or to the Java Runtime Environment (JRE) classes. By means of bytecode engineering and code generation, J-Orchestra substitutes method calls with remote method calls, direct object references with proxy references, etc. It also translates Java language features (e.g., static methods and fields, inheritance, inner classes, new object construction, etc.) for efficient distributed execution.We detail the main technical issues that J-Orchestra addresses, including its mechanism for program transformation in the presence of unmodifiable code (e.g., in JRE classes) and the translation of concurrency and synchronization constructs to work correctly over the network. We further discuss a case study of transforming a large, commercial, third-party application for efficient execution in a client server environment and outline the architectural characteristics of centralized programs that are amenable to automated distribution with J-Orchestra.

EventJava: An Extension of Java for Event Correlation

Abstract: Event correlation has become the cornerstone of many reactive applications, particularly in distributed systems. However, support for programming with complex events is still rather specific and rudimentary. This paper presents EventJava, an extension of Java with generic support for event-based distributed programming. EventJava seamlessly integrates events with methods, and broadcasting with unicasting of events; it supports reactions to combinations of events, and predicates guarding those reactions. EventJava is implemented as a framework to allow for customization of event semantics, matching, and dispatching. We present its implementation, based on a compiler transforming specific primitives to Java, along with a reference implementation of the framework. We discuss ordering properties of EventJava through a formalization of its core as an extension of Featherweight Java. In a performance evaluation, we show that EventJava compares favorably to a highly tuned database-backed event correlation engine as well as to a comparably lightweight concurrency mechanism.

Closing the gap between modelling and java

Abstract: Model-Driven Software Development is based on standardised models that are refined, transformed and eventually translated into executable code using code generators. However, creating plain text from well-structured models creates a gap that implies several drawbacks: Developers cannot continue to use their model-based tool machinery, relations between model elements and code fragments are hard to track and there is no easy way to rebuild models from their respective code. This paper presents an approach to bridge this gap for the Java programming language. It defines a full metamodel and text syntax specification for Java, from which a parser and a printer are generated. Through this, Java code can be handled like any other model. The implementation is validated with large test sets, example applications are shown, and future directions of research are discussed.

Efficient character-level taint tracking for Java

Abstract: Over 80% of web services are vulnerable to attack, and much of the danger arises from command injection vulnerabilities. We present an efficient character-level taint tracking system for Java web applications and argue that it can be used to defend against command injection vulnerabilities. Our approach involves modification only to Java library classes and the implementation of the Java servlets framework, so it requires only a one-time modification to the server without any subsequent modifications to a web application's bytecode or access to the web application's source code. This makes it easy to deploy our technique and easy to secure legacy web software. Our preliminary experiments with the JForum web application suggest that character-level taint tracking adds 0-15% runtime overhead.

I-JVM: a Java Virtual Machine for component isolation in OSGi

Abstract: The OSGi framework is a Java-based, centralized, component oriented platform. It is being widely adopted as an execution environment for the development of extensible applications. However, current Java Virtual Machines are unable to isolate components from each other. For instance, a malicious component can freeze the complete platform by allocating too much memory or alter the behavior of other components by modifying shared variables. This paper presents I-JVM, a Java Virtual Machine that provides a lightweight approach to isolation while preserving compatibility with legacy OSGi applications. Our evaluation of I-JVM shows that it solves the 8 known OSGi vulnerabilities that are due to the Java Virtual Machine and that the overhead of I-JVM compared to the JVM on which it is based is below 20%.

Java for Safety-Critical Applications

Abstract: In recent years, various approaches to real-time execution of Java have proven their worth in numerous commercial and defense applications. The Real-time Specification for Java has extended the Java platform with a range of features needed for real-time computing. As the use of real-time Java has become more widespread, the demand for Java in real-time applications with safety requirements has led to an eort to define a new standard—JSR-302 Safety-Critical Java (SCJ). The goal of this standard is to facilitate the creation of safety-critical Java applications capable of certification under standards such as DO 178B level A or IEC61508 for SIL 4. JSR-302 is nearing completion and will soon be released for public review. This paper introduces some of the primary goals, challenges, and proposed solutions for safety-critical Java and its relationship with the Real-time Specification for Java.

Real time Java on resource-constrained platforms with Fiji VM

Abstract: Real-time Java is quickly emerging as a platform for building safety-critical embedded systems. The real-time variants of Java, including [8, 15], are attractive alternatives to Ada and C since they provide a cleaner, simpler, and safer programming model. Unfortunately, current real-time Java implementations have trouble scaling down to very hard real-time embedded settings, where memory is scarce and processing power is limited. In this paper, we describe the architecture of the Fiji VM, which enables vanilla Java applications to run in very hard environments, including booting on bare hardware with only very rudimentary operating system support. We also show that our minimalistic approach delivers comparable performance to that of server-class production Java Virtual Machine implementations.

Finding bugs in exceptional situations of JNI programs

Abstract: Software flaws in native methods may defeat Java's guarantees of safety and security. One common kind of flaws in native methods results from the discrepancy on how exceptions are handled in Java and in native methods. Unlike exceptions in Java, exceptions raised in the native code through the Java Native Interface (JNI) are not controlled by the Java Virtual Machine (JVM). Only after the native code finishes execution will the JVM's mechanism for exceptions take over. This discrepancy makes handling of JNI exceptions an error prone process and can cause serious security flaws in software written using the JNI.We propose a novel static analysis framework to examine exceptions and report errors in JNI programs. We have built a complete tool consisting of exception analysis, static taint analysis, and warning recovery. Experimental results demonstrated this tool allows finding of mishandling of exceptions with high accuracy (15.4% false-positive rate on over 260k lines of code). Our framework can be easily applied to analyzing software written in other foreign function interfaces, including the Python/C interface and the OCaml/C interface.

Developing and Benchmarking Native Linux Applications on Android

Abstract: Smartphones get increasingly popular where more and more smartphone platforms emerge. Special attention was gained by the open source platform Android which was presented by the Open Handset Alliance (OHA) hosting members like Google, Motorola, and HTC. Android uses a Linux kernel and a stripped-down userland with a custom Java VM set on top. The resulting system joins the advantages of both environments, while third-parties are intended to develop only Java applications at the moment.

Advanced runtime adaptation for Java

Abstract: Dynamic aspect-oriented programming (AOP) enables runtime adaptation of aspects, which is important for building sophisticated, aspect-based software engineering tools, such as adaptive profilers or debuggers that dynamically modify instrumentation code in response to user interactions. Today, many AOP frameworks for Java, notably AspectJ, focus on aspect weaving at compile-time or at load-time, and offer only limited support for aspect adaptation and reweaving at runtime. In this paper, we introduce HotWave, an AOP framework based on AspectJ for standard Java Virtual Machines (JVMs). HotWave supports dynamic (re)weaving of previously loaded classes, and it ensures that all classes loaded in a JVM can be (re)woven, including the classes of the standard Java class library. HotWave features a novel mechanism for inter-advice communication, enabling efficient data passing between advices that are woven into the same method. We explain HotWave's programming model and discuss our implementation techniques. As case study, we present an adaptive, aspect-based profiler that leverages HotWave's distinguishing features.

Loci: Simple Thread-Locality for Java

Abstract: This paper presents a simple type system for thread-local data in Java. Classes and types are annotated to express thread-locality and unintended leaks are detected at compile-time. The system, called Loci, is minimal, modular and compatible with legacy code. The only change to the language is the addition of two new metadata annotations. We implemented Loci as an Eclipse plug-in and used it to evaluate our design on a number of benchmarks. We found that Loci is compatible with how Java programs are written and that the annotation overhead is light thanks to a judicious choice of defaults.

Genetic programming in the wild: evolving unrestricted bytecode

Abstract: We describe a methodology for evolving Java bytecode, enabling the evolution of extant, unrestricted Java programs, or programs in other languages that compile to Java bytecode. Bytecode is evolved directly, without any intermediate genomic representation. Our approach is based upon the notion of compatible crossover, which produces correct programs by performing operand stack-, local variables-, and control flow-based compatibility checks on source and destination bytecode sections. This is in contrast to existing work that uses restricted subsets of the Java bytecode instruction set as a representation language for individuals in genetic programming. Given the huge universe of unrestricted Java bytecode, as is programs, our work enables the applications of evolution within this realm. We experimentally validate our methodology by both extensively testing the correctness of compatible crossover on arbitrary bytecode, and by running evolution on a program that exploits the richness of the Java virtual machine architecture and type system.

A predictable Java profile: rationale and implementations

Abstract: A Java profile suitable for development of high integrity embedded systems is presented. It is based on event handlers which are grouped in missions and equipped with respectively private handler memory and shared mission memory. This is a result of our previous work on developing a Java profile, and is directly inspired by interactions with the Open Group on their on-going work on a safety critical Java profile (JSR-302). The main contribution is an arrangement of the class hierarchy such that the proposal is a generalization of Real-Time Specification for Java (RTSJ). A further contribution is to integrate the mission concept as a handler, such that mission memory becomes a handler private memory and such that mission initialization and finalization are scheduled activities. Two implementations are presented: one directly on an open source JVM using Xenomai and another, based on delegation, on an RTSJ platform.

A comparative study of Java and C performance in two large-scale parallel applications

Abstract: In the 1990s the Message Passing Interface Forum defined MPI bindings for Fortran, C, and C++. With the success of MPI these relatively conservative languages have continued to dominate in the parallel computing community. There are compelling arguments in favour of more modern languages like Java. These include portability, better runtime error checking, modularity, and multi-threading. But these arguments have not converted many HPC programmers, perhaps due to the scarcity of full-scale scientific Java codes, and the lack of evidence for performance competitive with C or Fortran. This paper tries to redress this situation by porting two scientific applications to Java. Both of these applications are parallelized using our thread-safe Java messaging system—MPJ Express. The first application is the Gadget-2 code, which is a massively parallel structure formation code for cosmological simulations. The second application uses the finite-domain time-difference method for simulations in the area of computational electromagnetics. We evaluate and compare the performance of the Java and C versions of these two scientific applications, and demonstrate that the Java codes can achieve performance comparable with legacy applications written in conventional HPC languages.

Towards a Next-Generation Matrix Library for Java

Abstract: Matrices are essential in many fields of computer science, especially when large amounts of data must be handled efficiently. Despite this demand for matrix software, we were unable to find a Java library which was flexible enough to match all our needs. In this paper, we present the Universal Java Matrix Package (UJMP), an innovative software architecture in Java to store and process matrices with interfaces to external data sources such as Excel files or SQL-databases, allowing to handle data which would not fit into main memory.In contrast to all other approaches which we are aware of, our package is the only one to support very large matrices with up to 2^63 rows or columns. In addition, the use of variable argument lists provides a convenient way for accessing multi-dimensional data without the need to specify dimensionality at compile time. Arbitrary data types be handled through the use of Java Generics. Another key feature is the strict separation of interfaces and classes, making data storage implementation and math engine exchangeable, at runtime. This flexible architecture allows the user to decide whether operations should be optimized for speed or memory usage and makes the system easily extendable through existing libraries, incorporating their individual strengths.

Lazy continuations for Java virtual machines

Abstract: Continuations, or 'the rest of the computation', are a concept that is most often used in the context of functional and dynamic programming languages. Implementations of such languages that work on top of the Java virtual machine (JVM) have traditionally been complicated by the lack of continuations because they must be simulated.We propose an implementation of continuations in the Java virtual machine with a lazy or on-demand approach. Our system imposes zero run-time overhead as long as no activations need to be saved and restored and performs well when continuations are used. Although our implementation can be used from Java code directly, it is mainly intended to facilitate the creation of frameworks that allow other functional or dynamic languages to be executed on a Java virtual machine.As there are no widely used benchmarks for continuation functionality on JVMs, we developed synthetical benchmarks that show the expected costs of the most important operations depending on various parameters.

An Evaluation of Current Java Bytecode Decompilers

Abstract: Decompilation of Java bytecode is the act of transforming Java bytecode to Java source code. Although easier than that of decompilation of machine code, problems still arise in Java bytecode decompilation. These include type inference of local variables and exception-handling. Since the last such evaluation (2003) several new commercial, free and open-source Java decompilers have appeared and some of the older ones have been updated. In this paper, we evaluate the currently available Java bytecode decompilers using an extension of the criteria that were used in the original study. Although there has been a slight improvement since this study, it was found that none passed all the tests, each of which were designed to target different problem areas. We give reasons for this lack of success and suggest methods by which future Java bytecode decompilers could be improved.

NPB-MPJ: NAS Parallel Benchmarks Implementation for Message-Passing in Java

Abstract: Java is a valuable and emerging alternative for the development of parallel applications, thanks to the availability of several Java message-passing libraries and its full multithreading support. The combination of both shared and distributed memory programming is an interesting option for parallel programming multi-core systems. However, the concerns about Java performance are hindering its adoption in this field, although it is difficult to evaluate accurately its performance due to the lack of standard benchmarks in Java.This paper presents NPB-MPJ, the first extensive implementation of the NAS Parallel Benchmarks (NPB), the standard parallel benchmark suite, for Message-Passing in Java (MPJ) libraries. Together with the design and implementation details of NPB-MPJ, this paper gathers several optimization techniques that can serve as a guide for the development of more efficient Java applications for High Performance Computing (HPC). NPB-MPJ has been used in the performance evaluation of Java against C/Fortran parallel libraries on two representative multi-core clusters. Thus, NPB-MPJ provides an up-to-date snapshot of MPJ performance, whose comparative analysis of current Java and native parallel solutions confirms that MPJ is an alternative for parallel programming multi-core systems.

Automated Annotation and Visualization of Rhetorical Figures

Abstract: Linguistic annotation provides additional information asserted with a particular purpose in a document or other piece of information. It is widely used in various fields, from computing and bioinformatics, through imaging, to law and linguistics. There is also a clear distinction between what is communicated through the written/spoken natural language and how this is passed on. A new problem of linguistic annotation is the annotation of classical rhetorical figures – patterns of text in which a characteristic syntactic form modifies the standard meanings of words, and leads to a change or an extension of meaning. Rhetoric studies the effectiveness of language comprehensively, including its emotional impact, as much as its propositional content. The annotation of rhetorical figures is therefore important not only for the linguistic point of view, but also for discovering different styles of writing, purpose and effect of written documents, and for better natural language understanding in general. The purpose of this thesis is the automated annotation of rhetorical figures. In the thesis we primarily focus on the figures of repetition, which include the repetition of words, phrases, and clauses. Additionally, we also describe the work we have done on the detection and annotation of figures of parallelism, as well as those that pertain more to the semantics than to the syntax, or positioning. We have developed a rhetorical figure annotation tool dubbed JANTOR (Java ANnotation Tool Of Rhetoric), which enables manual and automated annotation of files in HTML format. We have applied a lexicalized probabilistic context-free grammar parser for the recognition of the figures of repetition. We also describe a simple parse tree distance used for calculating the difference between similarly structured phrases, which is necessary for the recognition of some of the figures of parallelism. Moreover, we have applied the semantic relationships contained in the WordNet lexical database and extended Porter stemmer algorithm for finding derivationally related words. Finally, we present a method for finding pairs of words which are ordinarily contradictory, which is crucial for detecting the interesting figure of speech: oxymoron. For this purpose typed dependency grammars together with WordNet are used. The experiments we have conducted on the detection of selected subset of rhetorical figures have yielded very promising results. Lastly, we present the visualization of the occurrences of the figures and comparison between 14 American presidents' inaugural addresses including the most recent one by President Barack Obama. The provocative results of this comparison show that a) automated analysis of meaningful rhetorical information is possible and tractable, and b) help us with understanding what creates a successful orator.

Towards a dynamic-update-enabled JVM

Abstract: This paper advocates that de facto dynamic updates of Java applications will eventually require a dynamic-update-enabled Java virtual machine. We argue that our approach for dynamic updates of component-based Java applications complements the new module system planned for upcoming Java releases. We conclude that simple extensions to an existing JVM can bring full flexibility and transparency to dynamic updates in Java.

HotWave: creating adaptive tools with dynamic aspect-oriented programming in Java

Abstract: Developing tools for profiling, debugging, testing, and reverse engineering is error-prone, time-consuming, and therefore costly when using low-level techniques, such as bytecode instrumentation. As a solution to these problems, we promote tool development in Java using high-level aspect-oriented programming (AOP). We demonstrate that the use of aspects yields compact tools that are easy to develop and extend. As enabling technology, we rely on HotWave, a new tool for dynamic and comprehensive aspect weaving. HotWave reconciles compatibility with existing virtual machine and AOP technologies. It provides support for runtime adaptation of aspects and reweaving of previously loaded code, as well as the ability to weave aspects into all methods executing in a Java Virtual Machine, including methods in the standard Java class library. HotWave also features a new mechanism for efficiently passing data between advices that are woven into the same method. We demonstrate the benefits of HotWave's distinguishing features with two case studies in the area of profiling.

The LIME Interface Specification Language and Runtime Monitoring Tool

Abstract: This paper describes an interface specification language designed in the LIME project (LIME ISL) and the supporting runtime monitoring tool. The interface specification language is tailored for the Java programming language and supports two kinds of specifications: (i) call specifications that specify requirements for the allowed call sequences to a Java object instance and (ii) return specifications that specify the allowed behaviors of the Java object instance. Both the call and return specifications can be expressed with Java annotations in several different ways: as past time LTL formulas, as (safety) future LTL formulas, as regular expressions, and as nondeterministic finite automata. We also describe the supporting LIME interface monitoring tool which is an open source implementation of runtime monitoring for the interface specifications implemented using AspectJ.

Enhanced development tool for utilizing a javascript object notation (json) bridge for non-java-based component communication within java-based composite applications

Abstract: Utilizing a JAVASCRIPT Object Notation (JSON) bridge during JAVA-based composite application development can begin with the receipt of a command to present the wiring diagram of a JAVA-based composite application by an enhanced JAVA-based composite application development tool. The JAVA-based composite application can consist of one or more JAVA-based components and non-JAVA-based components, with one property of a JAVA-based component being communicatively wired to a non-JAVA-based component. A JSON bridge can acknowledge the accessing of the JAVA-based composite application. The wiring diagram of the JAVA-based composite application can then be visually rendered. For the property of the JAVA-based component communicatively wired to the non-JAVA-based component, a user-selectable option to utilize the JSON bridge for communication can be presented. With the JSON bridge option selected, user-entered changes to this property can automatically invoke the JSON bridge to communicate related data to the communicatively wired non-JAVA-based component.
