The Impact of RDMA on Agreement

Rachid Guerraoui, Mihail Igor Zablotchi, Naama Ben David

Remote Direct Memory Access (RDMA) is becoming widely available in data centers. This technology allows a process to directly read and write the memory of a remote host, with a mechanism to control access permissions. In this paper, we study the fundamenta ...

Improving Energy-Efficiency in Dynamic Memories Through Retention Failure Detection

Adam Shmuel Teman, Robert Giterman

A gain-cell embedded DRAM (GC-eDRAM) is an attractive logic-compatible alternative to the conventional static random access memory (SRAM) for the implementation of embedded memories, as it offers higher density, lower leakage, and two-ported operation. How ...

Detailed Heap Profiling

James Richard Larus, Stuart Anthony Byma

Modern software systems heavily use the memory heap. As systems grow more complex and compute with increasing amounts of data, it can be difficult for developers to understand how their programs actually use the bytes that they allocate on the heap and whe ...

Limitations of Partial Compaction: Towards Practical Bounds

Nachshon Cohen

Compaction of a managed heap is a costly operation to be avoided as much as possible in commercial runtimes. Instead, partial compaction is often used to defragment parts of the heap and avoid space blowup. Previous study of compaction limitation provided ...

Energy versus Data Integrity Trade-Offs in Embedded High-Density Logic Compatible Dynamic Memories

Andreas Peter Burg, Adam Shmuel Teman, Robert Giterman, Pascal Andreas Meinerzhagen, Georgios Karakonstantis

Current variation aware design methodologies, tuned for worst-case scenarios, are becoming increasingly pessimistic from the perspective of power and performance. A good example of such pessimism is setting the refresh rate of DRAMs according to the worst- ...

Asynchronous memory access chaining

Babak Falsafi, Boris Robert Grot, Yusuf Onur Koçberber

In-memory databases rely on pointer-intensive data structures to quickly locate data in memory. A single lookup operation in such data structures often exhibits long-latency memory stalls due to dependent pointer dereferences. Hiding the memory latency by ...

Improving Reliability of Embedded Systems through Dynamic Memory Manager Optimization using Grammatical Evolution

David Atienza Alonso, José Luis Risco Martin

Technology scaling has offered advantages to embedded systems, such as increased performance, more available memory and reduced energy consumption. However, scaling also brings a number of problems like reliability degradation mechanisms. The intensive act ...

Dynamic fragmentation of ceramics, signature of defects and scaling of fragment sizes

Jean-François Molinari, Sarah Levy

Defects play a critical role in the dynamic fragmentation process of structural ceramics. Cracks initiate at seemingly random locations, propagate and coalesce to form fragments. The process is accompanied by stress release waves, whose influence is diffic ...

A Parallel Evolutionary Algorithm to Optimize Dynamic Memory Managers in Embedded Systems

David Atienza Alonso, José Luis Risco Martin

For the last 30 years, several dynamic memory managers (DMMs) have been proposed. Such DMMs include first fit, best fit, segregated fit and buddy systems. Since the performance, memory usage and energy consumption of each DMM differs, software engineers of ...

Cost-efficient and Differentiated Data Availability Guarantees in Data Clouds

Karl Aberer, Nicolas Bonvin

Failures of any type are common in current datacenters. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In this paper, we propose a self- managed key-value stor ...

Simulation of High-Performance Memory Allocators

David Atienza Alonso, José Luis Risco Martin

Current general-purpose memory allocators do not provide sufficient speed or flexibility for modern highperformance applications. To optimize metrics like performance, memory usage and energy consumption, software engineers often write custom allocators fr ...

Optimization of Dynamic Memory Managers for Embedded Systems Using Grammatical Evolution

David Atienza Alonso, José Luis Risco Martin

New portable consumer embedded devices must execute multimedia applications (e.g., 3D games, video players and signal processing software, etc.) that demand extensive memory accesses and memory usage at a low energy consumption. Moreover, they must heavily ...

Mixed Heuristic and Mathematical Programming Using Reference Points for Dynamic Data Types Optimization in Multimedia Embedded Systems

David Atienza Alonso, José Luis Risco Martin

New multimedia embedded applications are becoming increasingly dynamic. Thus, they cannot only rely on static data allocation, and must employ Dynamically-allocated Data Types (DDTs) to store their data and efficiently use the limited physical resources of ...
