NrOS: Effective Replication and Sharing in an Operating System

Writing a correct operating system kernel is notoriously hard. Kernel code requires manual memory management and type-unsafe code and must efficiently handle complex, asynchronous events. In addition, increasing CPU core counts further complicate kernel de ...

The Battle of the Schedulers: FreeBSD ULE vs. Linux CFS

Willy Zwaenepoel, Baptiste Joseph Eustache Lepers, Sébastien Chevalley, Justinien Gérard Alain Bouron

This paper analyzes the impact on application performance of the design and implementation choices made in two widely used open-source schedulers: ULE, the default FreeBSD scheduler, and CFS, the default Linux scheduler. We compare ULE and CFS in otherwise ...

Modeling Asymmetric Operation in Double-Gate Junctionless FETs by Means of Symmetric Devices

Jean-Michel Sallese, Farzan Jazaeri, Lucian Barbut

This paper aims to model asymmetric operation in double gate junctionless FETs. Following a rigorous approach, we find that asymmetric operation can be simulated by combining two symmetric junctionless FETs, what we call the virtual symmetric device concep ...

Instant Pickles: Generating Object-Oriented Pickler Combinators for Fast and Extensible Serialization

Martin Odersky, Philipp Haller, Eugene Burmako

As more applications migrate to the cloud, and as “big data” edges into even more production environments, the performance and simplicity of exchanging data between compute nodes/devices is increasing in importance. An issue central to distributed programm ...

Lightweight Snapshots and System-level Backtracking

George Candea, Edouard Bugnion, Vitaly Chipounov

We propose a new system-level abstraction, the lightweight immutable execution snapshot, which combines the immutable characteristics of checkpoints with the direct integration into the virtual memory subsystem of standard mutable address spaces. The abstr ...

High-Performance RMA-Based Broadcast on the Intel SCC

André Schiper, Thomas Ropars, Omid Shahmirzadi, Darko Petrovic

Many-core chips with more than 1000 cores are expected by the end of the decade. To overcome scalability issues related to cache coherence at such a scale, one of the main research directions is to leverage the message-passing programming model. The Intel ...
