Concurrent logic languages have been used mainly for the (parallel) processing of rather irregular symbolic applications. However, since concurrent logic languages are essentially general-purpose, they should be applicable to problems with regular structures and their data-parallel processing as well. This paper studies the possibility of massively parallel processing in concurrent logic progra...

This thesis presents a new, Java-based object-oriented parallel language called Deterministic Parallel Java (DPJ). DPJ uses a novel effect system to guarantee determinism by default. That means that parallel programs are guaranteed to execute deterministically unless nondeterminism is explicitly requested. This is in contrast to the shared-memory models in widespread use today, such as threads ...

Any parallel programming language provides a model of par-allelism, and one can write a program directly in the language, accepting the xed given model. We propose an alternative methodology: the program is derived in a sequence of steps, where each step incorporates just one decision, and is based on a speciic model of parallelism, called an abstract parallel machine, which is chosen to be sui...

In this paper, we introduce a novel approach to generate synthetic data for training Neural Machine Translation systems. The proposed approach transforms a given parallel corpus between a written language and a target language to a parallel corpus between a spoken dialect variant and the target language. Our approach is language independent and can be used to generate data for any variant of th...

Java 1 has emerged as a dominant language that could eventually replace C++. It is believed that using Java would boost programmer productivity because of its well-thought design, independence from backward-compatibility with C, absence of arbitrary pointers, etc. We present the design and implementation of a parallel extension to Java. The parallel extension provides dynamic creation of remote...

To provide various parallel language constructs, extensible languages based on re ection are attractive for both implementors and users. This paper describes our proposed meta-level architecture of a concurrent object-oriented language ABCL/R3, which has the following characteristics: (1) language customization through meta-interpreters and meta-objects, (2) delegation and inheritance mechanism...

It is widely recognized that a key problem of parallel computation is in the development of both e cient and correct parallel software. Although many advanced language features and compilation techniques have been proposed to alleviate the complexity of parallel programming, much e ort is still required to develop parallelism in a formal and systematic way. In this paper, we intend to clarify t...

Recently, there is increasingly globalized world. We developed a multilingual parallel-text sharing system for multilingual communication. A parallel-text requires one-on-one combination among each language. However, parallel texts often have example sentences of many-to-many combination among each language. A multiplicity of expression causes this problem. It is difficult to solve this problem...

We present a parallel logic language which uses the bulk synchronous parallelism (BSP) execution model 13]. The BSP model provides a simple way to program parallel machines by restricting the SPMD style : processes are limited to a bounded asynchronism during local computations and communication is a global operation followed by a global synchronization. This in conjunction with explicit locati...
