Software Synthesis Procedures

Viktor Kuncak, Mikaël Mayer, Philippe Paul Henri Suter, Ruzica Piskac

Automated synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, software synthesis algorithms should behave in a predictable way: they should succ ...

Bringing Virtualization to the x86 Architecture with the Original VMware Workstation

Edouard Bugnion

This article describes the historical context, technical challenges, and main implementation techniques used by VMware Workstation to bring virtualization to the x86 architecture in 1999. Although virtual machine monitors (VMMs) had been around for decades ...

It's the End of the World as We Know It (And I Feel Fine)

James Richard Larus

The end of Dennard scaling and the imminent end of semiconductor feature scaling means that software systems and applications will no longer benefit from 40% per annum performance increases, a continually rising tide that lifted all boats. Future software ...

Spatiotemporal Coherence Tracking

Mohammad Alisafaee

Chip-multiprocessors require a coherence directory to track data sharing and order accesses to the shared data. Scaling coherence directories to support a large number of cores is challenging due to excessive area requirements of the directories. The state ...

CoRD: A Collaborative Framework for Distributed Data Race Detection

George Candea, Cristian Zamfir, Baris Can Cengiz Kasikci

Modern concurrent software is riddled with data races and these races constitute the source of many problems. Data races are hard to detect accurately before software is shipped and, once they cause failures in production, developers find it challenging to ...

On the cost of composing shared-memory algorithms

Rachid Guerraoui, Dan Alistarh, Giuliano Losa

Decades of research in distributed computing have led to a variety of perspectives on what it means for a concurrent algorithm to be efficient, depending on model assumptions, progress guarantees, and complexity metrics. It is therefore natural to ask whet ...

DejaVu: Accelerating Resource Allocation in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini

Effective resource management of virtualized environments is a challenging task. State-of-the-art management systems either rely on analytical models or evaluate resource allocations by running actual experiments. However, both approaches incur a significa ...

Performance Profiling of Virtual Machines

Willy Zwaenepoel, Jiaqing Du

Profilers based on hardware performance counters are indispensable for performance debugging of complex software systems. All modern processors feature hardware performance counters, but current virtual machine monitors (VMMs) do not properly expose them t ...
