Thermal Characterization of Cloud Workloads on a Power-Efficient Server-on-Chip

Babak Falsafi, Pejman Lotfi Kamran, Andreas Panteli

We propose a power-efficient many-core server-on-chip system with 3D-stacked Wide I/O DRAM targeting cloud workloads in datacenters. The integration of 3D-stacked Wide I/O DRAM on top of a logic die increases available memory bandwidth by using dense and f ...

Comprehensive Performance Metrics for Complex Fenestration Systems Using a Relative Approach

Buildings account for over 40% of the energy consumption in the United States, nearly 40% of which is attributed to lighting. The selection of a fenestration system for a building is a critical decision as it offsets electric lighting use as well as impact ...

Practical and Policy-Relevant Performance Metrics for Complex Fenestration Systems

Marilyne Andersen

The selection of a fenestration system for a building is critical, as it impacts energy performance, occupant comfort, and ambiance of a space. Complex Fenestration Systems (CFS) address these criteria using a wide variety of novel technologies but are dif ...

A Data-oriented Transaction Execution Engine and Supporting Tools

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Frederick Ryan Johnson, Pinar Tözün, Ippokratis Pandis, Danica Porobic, Dimitrios Karampinas

Conventional OLTP systems assign each transaction to a worker thread and that thread accesses data, depending on what the transaction dictates. This thread-to-transaction work assignment policy leads to unpredictable accesses. The unpredictability forces e ...

Attaining Single-Chip, High-Performance Computing Through 3D Systems with Active Cooling

David Atienza Alonso, Mohamed Mostafa Sabry Aly, Ayse Kivilcim Coskun, Jie Meng

Three-dimensional (3D) stacking is an attractive method for designing large manycore chips as it provides high transistor integration densities, improves manufacturing yield due to smaller chip area, reduces wirelength and capacitance, and enables heteroge ...

Model Checking of Distributed Algorithm Implementations

Maysam Yabandeh

It is notoriously difficult to develop reliable, high-performance distributed systems that run over asynchronous networks. Even if a distributed system is based on a well-understood distributed algorithm, its implementation can contain errors arising from ...

PaxosInside

Rachid Guerraoui, Maysam Yabandeh

Amodernmanycore architecture can be viewed as a distributed system with explicit message passing to communicate between cores. Ensuring the consistency of shared state replicated over several cores is the key to the well functioning of such a system. Yet, ...

Inducing Thermal-Awareness in Multicore Systems Using Networks-on-Chip

David Atienza Alonso

Technology scaling imposes an ever increasing temperature stress on digital circuit design due to transistor density, especially on highly integrated systems, such as Multi- Processor Systems-on-Chip (MPSoCs). Therefore, temperature-aware design is mandato ...
