Finally, a Polymorphic Linear Algebra Language

Amir Shaikhha, Lionel Emile Vincent Parreaux

Many different data analytics tasks boil down to linear algebra primitives. In practice, for each different type of workload, data scientists use a particular specialised library. In this paper, we present Pilatus, a polymorphic iterative linear algebra la ...

Integrating Heuristic and Machine-Learning Methods for Efficient Virtual Machine Allocation in Data Centers

David Atienza Alonso, Marina Zapater Sancho, Ali Pahlevan

Modern cloud data centers (DCs) need to tackle efficiently the increasing demand for computing resources and address the energy efficiency challenge. Therefore, it is essential to develop resource provisioning policies that are aware of virtual machine (VM ...

Energy Proportionality in Near-Threshold Computing Servers and Cloud Data Centers: Consolidating or Not?

David Atienza Alonso, Luca Benini, Marina Zapater Sancho, Yasir Mahmood Qureshi, Ali Pahlevan

Cloud Computing aims to efficiently tackle the increasing demand of computing resources, and its popularity has led to a dramatic increase in the number of computing servers and data centers worldwide. However, as effect of post-Dennard scaling, computing ...

Miniboxing: Improving the Speed to Code Size Tradeoff in Parametric Polymorphism Translations

Martin Odersky, Vlad Ureche

Parametric polymorphism enables code reuse and type safety. Underneath the uniform interface exposed to programmers, however, its low level implementation has to cope with inherently non-uniform data: value types of different sizes and semantics (bytes, in ...

Towards Static Analysis of Virtualization-Obfuscated Binaries

Johannes Kinder

Virtualization-obfuscation protects a program from manual or automated analysis by compiling it into bytecode for a randomized virtual architecture and attaching a corresponding interpreter. Static analysis appears to be helpless on such programs, where on ...

TwinDrivers: Semi-Automatic Derivation of Fast and Safe Hypervisor Network Drivers from Guest OS Drivers

Willy Zwaenepoel, Simon Schubert

In a virtualized environment, device drivers are often run inside a virtual machine (VM) rather than in the hypervisor. Doing so protects the hypervisor from bugs in the driver, and also allows the reuse of the device driver and its support infrastructure ...

Exploration of Memory Hierarchy Configurations for Efficient Garbage Collection on High-Performance Embedded Systems

David Atienza Alonso

Modern embedded devices (e.g., PDAs, mobile phones) are now incorporating Java as a very popular implementation language in their designs. These new embedded systems include multiple applications that are dynamically launched by the user, which can produce ...

Program Transformations for Light-Weight CPU Accounting and Control in the Java Virtual Machine - A Systematic Review

This article constitutes a thorough presentation of an original scheme for portable CPU accounting and control in Java, which is based on program transformation techniques at the bytecode level and can be used with every standard Java Virtual Machine. In o ...

Reflexes: Abstractions for Highly Responsive Systems

Rachid Guerraoui, Jesper Honig Spring

Commercial Java virtual machines are designed to maximize the performance of applications at the expense of predictability. High throughput garbage collection algorithms, for example, can introduce pauses of 100 milliseconds or more. We are interested in s ...

A Quantitative Evaluation of the Contribution of Native Code to Java Workloads

Many performance analysis tools for Java focus on tracking executed bytecodes, but provide little support in determining the specific contribution of native code libraries. This paper introduces and assesses a portable approach for characterizing the amoun ...

Towards CPU Load Prediction for Java Bytecode

This paper studies the use of bytecode instruction counting (BIC) to estimate the CPU load due to the execution of Java programs in different environments. BIC is the basis of the J-RAF2 framework to monitor and control the resource consumption of Java cod ...

Intellectual property management and protection for multimedia content : a structured language for interoperable IPMP systems

Claudio Paolo Alberti

Nowadays, network infrastructures are increasingly used in support to commercialization of digital multimedia content. Such kind of non-material goods, namely videos, music, still images and any other type of multi-media information are ready for the migra ...
