polyglot programming provides software developers with a broader choice in terms of software libraries and frameworks available for building applications. Previous research and engineering activities have focused on language interoperability and the design and implementation of fast polyglot runtimes. To make polyglot programming more approachable for developers, novel software development tools are needed that help them build polyglot applications. We believe a suitable prototyping platform helps to more quickly evaluate new ideas for such tools. In this paper we present GraalSqueak, a Squeak/Smalltalk virtual machine implementation for the GraalVM. We report our experience implementing GraalSqueak, evaluate the performance of the language and the programming environment, and discuss how the system can be used as a tooling platform for polyglot programming.

polyglot programming is the practice of using multiple programming languages in the same project. While many developers use this practice of polyglot programming, its effect on developers remains largely unexplored in the literature. In this extended abstract, I present preliminary efforts to provide empirical evidence to explain these effects using eye tracking in a randomized controlled trial study. 31 participants completed tasks in three different language variants. The results show that for certain tasks, the language variants produced a significant difference in gaze transition rates between different line types. Future extensions to this study are proposed to better understand these effects in other tasks and domains.

Utilization of various agile development practices brings demand of short development cycle with stress on early deployment and rapid delivery. Such practices require techniques permitting rapid prototyping of systems, corresponding tests and simulations. One of the well-adopted rapid prototyping techniques is polyglot programming combining multiple, mainly scripting, languages during development of systems. This permits the use of a specialized language for dedicated system concerns and also allows for a continuous change and re-deployment of implementation. Despite the advantages, rapid prototyping with help of polyglot programming is still not well supported in the domain of component-based systems, which makes it difficult to quickly prototype and test these systems. To address the obstacle, the paper describes a general technique for transparent and extensible combining of multiple languages for purpose of rapid prototyping during development of component-based systems with help of advanced component frameworks.

A taxonomy of cross-language linking mechanisms in open source frameworks

COMPUTING 2017年第7期99卷 701-724页

Non-trivial software systems are written using multiple programming languages. While the logic of a system is encoded using one or several general-purpose languages, more specialized parts of the systems are realized using domain-specific languages for aspects such as the user interface, configuration mechanisms, querying of databases, or support for internationalization. To bind all of these different parts together, the artifacts in individual languages are connected by using cross-language links which address artifacts across language boundaries. Many different ways for specifying and using such links have been conceived, and developers have to adhere to the concrete rules mandated by the runtime, framework or library which later performs the link resolution. In this paper, we present a taxonomy of the mechanisms of encoding cross-language linking in well-known open source frameworks from a developers perspective, which shows the choices that have been made and the options available in practice. We describe the process we followed, which is based in part on a survey of language combinations on GitHub and a survey of professional developers, list the dimensions and characteristics of our taxonomy in full, show the classifications of 22 frameworks and mechanisms, four of which are described in detail, and discuss the impact of the choices on application developers.

As sequencing technologies continue to drop in price and increase in throughput, new challenges emerge for the management and accessibility of genomic sequence data. We have developed a pipeline for facilitating the storage, retrieval, and subsequent analysis of molecular data, integrating both sequence and metadata. Taking a polyglot approach involving multiple languages, libraries, and persistence mechanisms, sequence data can be aggregated from publicly available and local repositories. Data are exposed in the form of a RESTful web service, formatted for easy querying, and retrieved for downstream analyses. As a proof of concept, we have developed a resource for annotated HIV-1 sequences. Phylogenetic analyses were conducted for >6,000 HIV-1 sequences revealing spatial and temporal factors influence the evolution of the individual genes uniquely. Nevertheless, signatures of origin can be extrapolated even despite increased globalization. The approach developed here can easily be customized for any species of interest.

With the rise of polyglot programming, different programming languages with different constructs have been combined in the same software development projects. However, to our knowledge, no axiomatization demonstrating the existential commitments of a language have been presented, nor is there effort to adopt a consensual conceptualization between languages, in particular object-oriented ones. In this paper, we propose OOC-O, a reference ontology on Object-Oriented Code whose purpose is to identify and represent the fundamental concepts present in OO source code. The ontology is based on UFO, was developed according to the SABiO method, verified according to its competency questions and validated by instantiation of concepts in OO code form and a process of harmonization among popular object-oriented languages.

Programs written in multiple languages are known as polyglot programs. In part due to the proliferation of new and productive high-level programming languages, these programs are becoming more common in environments that must interoperate with existing systems. polyglot programs must manage resource lifetimes across language boundaries. Resource lifetime management bugs can lead to leaks and crashes, which are more difficult to debug in polyglot programs than monoglot programs. We present analyses to automatically infer the ownership semantics of C libraries. The results of these analyses can be used to generate bindings to C libraries that intelligently manage resources, to check the correctness of polyglot programs, and to document the interfaces of C libraries. While these analyses are unsound and incomplete, we demonstrate that they significantly reduce the manual annotation burden for a suite of fifteen open source libraries.

Developing non-trivial software applications involves using multiple programming languages. Although each language is used to describe a particular aspect of the system, artifacts defined inside those languages reference each other across language boundaries;such references are often only resolved at runtime. However, it is important for developers to be aware of these references during development time for programming understanding, bug prevention, and refactoring. In this work, we report on a) an approach and tool for automatically identifying multi-language relevant artifacts, finding references between artifacts in different languages, and (rename-) refactoring them, and b) on an experimental evaluation of the approach on seven open-source case studies which use a total of six languages found in three frameworks. As our main result, we provide insights into the incidence of multi-language bindings in the case studies as well as the feasibility of automated multi-language rename refactorings.

In modern applications, it has become increasingly necessary to use multiple languages in a coordinated way to deal with the complexity and diversity of concerns encountered during development. This practice is known as polyglot programming. However, while execution platforms for polyglot programs are increasingly mature, there is a lack of support in how to test polyglot programs. This paper is a first step to increase awareness about polyglot testing efforts. It provides an overview of how polyglot programs are constructed, and an analysis of the impact on test writing at its different steps. More speciffcally, we focus on dynamic white box testing, and how polyglot programming impacts selection of input data, scenario specification and execution, and oracle expression. We discuss the related challenges in particular with regards to the current state of the practice. We envision in this paper to raise interest in polyglot program testing within the software engineering community, and help in defining directions for future work.

Hardware accelerators have always been difficult to approach. In recent years, we have experienced great efforts to simplify their programming paradigms, especially on CPUs. This led to the development of various domain-specific frameworks and microarchitectural features that facilitated some aspects of this multifaced problem. One such feature is the Unified Virtual Memory (UVM) oversubscription mechanism that allows the developer to handle datasets with a bigger memory footprint than the HW accelerators. Although promising, current UVM faces extreme overheads when running large workloads that reach an oversubscription factor (allocated vs. available memory) ampler than a per-workload threshold. In this work, we propose GrOUT, a language- and domain-agnostic framework that tackles the slowdowns brought by the UVM oversubscription mechanism. In particular, we highlight how a scale-out approach is a feasible solution to solve the slowdowns brought by UVM on workloads from various domains. Moreover, we design a framework capable of autonomously scaling out user-provided workloads, reaching a speedup of more than 24.42x with minimal changes to the application logic.
