System and method for user data input to modify operating mode configurations

A computer-implemented method, computer program product and computer system (100) for editing a configuration of a physical entity (30) to configure a future operating mode of a physical entity. A GUI component (200) provides a visual representation of a t ...

SoK: Shining Light on Shadow Stacks

Mathias Josef Payer, Xiangyu Zhang

Control-Flow Hijacking attacks are the dominant attack vector against C/C++ programs. Control-Flow Integrity (CFI) solutions mitigate these attacks on the forward edge, i.e., indirect calls through function pointers and virtual calls. Protecting the backwa ...

Fermi resonance in CO2: Mode assignment and quantum nuclear effects from first principles molecular dynamics

Sara Bonella, Guillaume André Jean Fraux

Vibrational spectroscopy is a fundamental tool to investigate local atomic arrangements and the effect of the environment, provided that the spectral features can be correctly assigned. This can be challenging in experiments and simulations when double pea ...

Interface Stresses in Cracked Concrete: Testing for Review of Its Fundamentals, High Tech Concrete: Where Technology and Engineering Meet

Aurelio Muttoni, Max Tirassa, Guillaume Anciaux, Miguel Fernández Ruiz

Aggregate interlock is one of the most significant stress transfer actions in cracked concrete and its understanding is fundamental in order to predict the strength of many concrete structures, particularly members failing in shear. Several test programmes ...

Enabling efficient OS paging for main-memory OLTP databases

Anastasia Ailamaki, Radu Ioan Stoica

Even though main memory is becoming large enough to fit most OLTP databases, it may not always be the best option. OLTP workloads typically exhibit skewed access patterns where some records are hot (frequently accessed) but many records are cold (infrequen ...

A cohesive element model for mixed mode loading with frictional contact capability

Jean-François Molinari, Leonardo Snozzi

We present a model that combines interface debonding and frictional contact. The onset of fracture is explicitly modeled using the well-known cohesive approach. Whereas the debonding process is controlled by a new extrinsic traction separation law, which a ...

A Scalable and Adaptive Technique for Compensating Process Variations and Controlling Leakage and Delay in the FPGA

Yusuf Leblebici, Christian Piguet, Bahman Kheradmand Boroujeni

A new circuit style is proposed to tune the delay, subthreshold leakage (ISUB), and gate leakage (IG) of high fan-in multiplexer circuits, such as the FPGA Look-Up Table (LUT) and Switch-Box (SB), without increasing the Gate Induced Drain Leakage (GIDL) cu ...

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 ...

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 ...

System for generating computer processor

A method and apparatus to produce a net list of gates and Flip-Flops for one algorithm in order to find the best compromise between power consumption, speed and silicon surface by using a two step process. First the algorithm is written for a processor tha ...

Performance Profiling in a Virtualized Environment

Willy Zwaenepoel, Jiaqing Du

Virtualization is a key enabling technology for cloud computing. Many applications deployed in a cloud run in virtual machines. However, profilers based on CPU performance counters do not work well in a virtualized environment. In this paper, we explore th ...

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

Willy Zwaenepoel, Aravind Menon, 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 ...

Demonstration of Electron-Bernstein-Wave Heating in a Tokamak via O-X-B Double-Mode Conversion

Laurie Porte, Antoine Pochelon, Yann Camenen, Loïc Curchod

The first demonstration of electron-Bernstein-wave heating by double-mode conversion from the O to the X mode in an overdense H-mode tokamak plasma has been achieved in the Tokamak a` Configuration Variable device. This technique overcomes the upper densit ...

Concurrent Direct Network Access for Virtual Machine Monitors

Willy Zwaenepoel, Aravind Menon

This paper presents hardware and software mechanisms to enable concurrent direct network access (CDNA) by operating systems running within a virtual machine monitor. In a conventional virtual machine monitor, each operating system running within a virtual ...
