Leveraging Parallel Nesting in Transactional Memory

Rachid Guerraoui, Michal Kapalka, Aleksandar Dragojevic

Exploiting the emerging reality of affordable multi-core architectures goes through providing programmers with simple abstractions that would enable them to easily turn their sequential programs into concurrent ones that expose as much parallelism as possi ...

Optimizing Transactions for Captured Memory

Aleksandar Dragojevic

In this paper, we identify transaction-local memory as a major source of overhead from compiler instrumentation in software transactional memory (STM). Transaction-local memory is memory allocated inside a transaction, which cannot escape (i.e., is capture ...

NoC Design and Implementation in 65 nm Technology

Giovanni De Micheli, David Atienza Alonso, Luca Benini, Srinivasan Murali, Federico Angiolini

As embedded computing evolves towards ever more powerful architectures, the challenge of properly interconnecting large numbers of on-chip computation blocks is becoming prominent. Networks-on-Chip (NoCs) have been proposed as a scalable solution to both p ...

A Packing Approach to Compare Slotted and Non-Slotted Medium Access Control

Patrick Thiran, Mathilde Durvy

In multi-hop ad hoc networks, the efficiency of a medium access control protocol under heavy traffic load depends mainly on its ability to schedule a large number of simultaneous non-interfering transmissions. However, as each node has only a local view of ...

Towards a Unified Top-Down Design Flow for Fully-Differential Logic Blocks with Improved Speed and Noise Immunity

Yusuf Leblebici, Stéphane Badel, Ilhan Hatirnaz

A new top-down design flow (RTL-to-GDSII) is proposed for achieving high-performance and noiseimmune designs consisting of differential logic blocks. The differential building blocks are based on the currentmode logic (CML), which offers true differentiali ...

Temporal Streaming of Shared Memory

Anastasia Ailamaki, Babak Falsafi

Coherent read misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. We propose Temporal Streaming, to eliminate coherent read misses by streaming data to a proces ...

A case for asymmetric-cell cache memories

Babak Falsafi

In this paper, we make the case for building high-performance asymmetric-cell caches (ACCs) that employ recently-proposed asymmetric SRAMs to reduce leakage proportionally to the number of resident zero bits. Because ACCs target memory value content (indep ...

Store-Ordered Streaming of Shared Memory

Anastasia Ailamaki, Babak Falsafi

Coherence misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. Memory streaming provides a promising solution to the coherence miss bottleneck because it improve ...

128 channel PCI-based data acquisition system for MDSplus

Basil Duval, Xavier Llobet

With the increasing demand for analogue channel acquisition on the TCV tokamak, a new PCI based acquisition has been specified, designed, built and installed into our MDSplus acquisition environment. The design criteria were to not only improve the cost/ch ...

Characterization of density fluctuations during ELMs in the DIII-D tokamak

Stefano Coda

Bursts of turbulence associated with ELMs have been studied systematically in DIII-D with a multichannel phase contrast imaging (PCI) diagnostic, which is sensitive to the long poloidal wavelength components of the density fluctuations in the outer edge of ...
