  • Supporting C Extensions for Dynamic Languages an Abbreviated Version of [10]
    High-Performance Language Composition: Supporting C Extensions for Dynamic Languages An abbreviated version of [10]. Grimmer Matthias1, Chris Seaton2, Thomas W¨urthinger2 and Hanspeter M¨ossenb¨ock1 1 Johannes Kepler University, Linz, Austria fgrimmer,[email protected] 2 Oracle Labs fchris.seaton,[email protected] Abstract. Many dynamic languages such as Ruby offer functionality for writing parts of applications in a lower-level language such as C. These C extension modules are usually written against the API of an interpreter, which provides access to the higher-level language's internal data struc- tures. Alternative implementations of the high-level languages often do not support such C extensions because implementing the same API as in the original implementations is complicated and limits performance. In this paper we describe a novel approach for modular composition of languages that allows dynamic languages to support C extensions through interpretation. We propose a flexible and reusable cross-language mechanism that allows composing multiple language interpreters. This mechanism allows us to efficiently exchange runtime data across different interpreters and also enables the dynamic compiler of the host VM to inline and optimize programs across multiple language boundaries. We evaluate our approach by composing a Ruby interpreter with a C interpreter. We run existing Ruby C extensions and show how our system executes combined Ruby and C modules on average over 3× faster than the conventional implementation of Ruby with native C extensions. 1 Introduction Most programming languages offer functionality for calling routines in modules that are written in another language. There are multiple reasons why program- mers want to do this, including to run modules already written in another lan- guage, to achieve higher performance than is normally possible in the primary language, or generally to allow different parts of the system to be written in the most appropriate language.

  • High Availability Framework for Mix-Cloud Secure Applications
    PETR BELYAEV HIGH AVAILABILITY FRAMEWORK FOR MIX-CLOUD SE- CURE APPLICATIONS Master of Science thesis Examiners: Prof. Jose Luis Martinez Lastra, Dr. Andrei Lobov Examiners and topic approved by the Faculty Council of the Faculty of Automation and Science Engineering on 6th April 2016 i ABSTRACT PETR BELYAEV: High Availability Framework for Mix-Cloud Secure Applications Tampere University of Technology Master of Science thesis, 53 pages, 6 Appendix pages November 2016 Master's Degree Programme in Automation Technology Major: Factory Automation and Industrial Informatics Examiners: Prof. Jose Luis Martinez Lastra, Dr. Andrei Lobov Keywords: High Availability, clustering, cloud Having one of the services, such as web applications, databases or telephony systems, unavailable because of a single server failure is very annoying, yet very common issue, especially if the service is deployed on-premises. The simplest way to address it is to introduce redundancy to the system. But in this case the amount of physical machines needed will raise, while their eciency will drop as most of the services do not use 100% of machine's capabilities. The better way to solve the service availability issue is to logically separate the service from the underlying hardware, balancing the load between instances and migrating them between the physical machines in case of failure. This way is much more eective, but it also contains a number of challenges, such as conguration diculty and inter-service request routing. The High Availability (HA) framework discussed in this thesis was designed to miti- gate those issues. The key goal solved by the HA framework is raising the scalability and reliability of the service while keeping the conguration as simple as possible.

  • Load Testing of Containerised Web Services
    UPTEC IT 16003 Examensarbete 30 hp Mars 2016 Load Testing of Containerised Web Services Christoffer Hamberg Abstract Load Testing of Containerised Web Services Christoffer Hamberg Teknisk- naturvetenskaplig fakultet UTH-enheten Load testing web services requires a great deal of environment configuration and setup. Besöksadress: This is especially apparent in an environment Ångströmlaboratoriet Lägerhyddsvägen 1 where virtualisation by containerisation is Hus 4, Plan 0 used with many moving and volatile parts. However, containerisation tools like Docker Postadress: offer several properties, such as; application Box 536 751 21 Uppsala image creation and distribution, network interconnectivity and application isolation that Telefon: could be used to support the load testing 018 – 471 30 03 process. Telefax: 018 – 471 30 00 In this thesis, a tool named Bencher, which goal is to aid the process of load testing Hemsida: containerised (with Docker) HTTP services, is http://www.teknat.uu.se/student designed and implemented. To reach its goal Bencher automates some of the tedious steps of load testing, including connecting and scaling containers, collecting system metrics and load testing results to name a few. Bencher’s usability is verified by testing a number of hypotheses formed around different architecture characteristics of web servers in the programming language Ruby. With a minimal environment setup cost and a rapid test iteration process, Bencher proved its usability by being successfully used to verify the hypotheses in this thesis. However, there is still need for future work and improvements, including for example functionality for measuring network bandwidth and latency, that could be added to enhance process even further. To conclude, Bencher fulfilled its goal and scope that were set for it in this thesis.

  • Inter-Language Collaboration in an Object-Oriented Virtual Machine Bachelor’S Thesis
    Inter-language Collaboration in an Object-oriented Virtual Machine Bachelor’s Thesis MATTHIAS SPRINGER, Hasso Plattner Institute, University of Potsdam TIM FELGENTREFF, Hasso Plattner Institute, University of Potsdam (Supervisor) TOBIAS PAPE, Hasso Plattner Institute, University of Potsdam (Supervisor) ROBERT HIRSCHFELD, Hasso Plattner Institute, University of Potsdam (Supervisor) Multi-language virtual machines have a number of advantages. They allow software developers to use soft- ware libraries that were written for different programming languages. Furthermore, language implementors do not have to bother with low-level VM functionality and their implementation can benefit from optimiza- tions in existing virtual machines. MagLev is an implementation of the Ruby programming language on top of the GemStone/S virtual machine for the Smalltalk programming language. In this work, we present how software components written in both languages can interact. We show how MagLev unifies the Smalltalk and the Ruby object model, taking into account Smalltalk meta classes, Ruby singleton classes, and Ruby modules. Besides, we show how we can call Ruby methods from Smalltalk and vice versa. We also present MagLev’s concept of bridge methods for implementing Ruby method calling conventions. Finally, we compare our solution to other language implementations and virtual machines. Additional Key Words and Phrases: Virtual Machines, Ruby, Smalltalk, MagLev, Language Implementation 1. MULTI-LANGUAGE VIRTUAL MACHINES Multi-language virtual machines are virtual machines that support the execution of source code written in multiple languages. According to Vraný [Vraný 2010], we have to distinguish multi-lanuguage virtual machines from interpreters and native code execution. Languages inside multi-language virtual machines are usually compiled to byte code and share the same object space.
