The choice of a communication paradigm, or protocol, is central to the design of a largescale multiprocessor system. Unlike traditional multiprocessors, the FLASH machine uses a programmable node controller, called MAGIC, to implement all protocol processing. The architecture of the MAGIC chip allows FLASH to support multiple communication paradigms — in particular, cache-coherent shared memory...

This paper considers the reliability of software Distributed Shared Memory systems where the unit of sharing is a persistent read-write object. We present an extended coherence protocol for causal consistency model, which integrates replication management with independent checkpointing. It uses a novel coordinated burst checkpoint operation in order to replicate consistent checkpoints of shared...

Transactional memory systems trade ease of programming with runtime performance losses in handling transactions. This paper focuses on starvation effects that show up in systems where unordered transactions are committed on a demand-driven basis. Such simple commit arbitration policies are prone to starvation. The design issues for commit arbitration policies are analyzed and novel policies tha...

The performance of the Time Warp mechanism is experimentally evaluated when only a limited amount of memory is available to the parallel computation. An implementation of the cancelback protocol is used for memory management on a shared memory architecture, viz., KSR to evaluate the performance vs. memory tradeoff. The implementation of the cancelback protocol supports canceling back more than ...

The Aplysia feeding system with its high degree of plasticity and well characterized neuronal circuitry is well suited for investigations of memory formation. We used an operant paradigm, learning that food is inedible (LFI), to investigate the signaling pathways underlying intermediate-term memory (ITM) in Aplysia. During a single massed training session, the animal associates a specific seawe...

The benefits of an organizational memory are ultimately determined by the usefulness of the organizational memory as perceived by its users. Therefore, an improvement of an organizational memory should be measured in the added perceived usefulness. Unfortunately, the perceived usefulness has many impact factors (e.g., the precision of the user query, the urgency with which the user needs inform...

Augmenting the LTE evolved NodeB with cloud resources offers a low-latency, resilient, and LTE-aware environment for offloading the Internet of Things (IoT) services and applications. By means of devices memory replication, the IoT applications deployed at an LTE integrated edge cloud can scale its computing and storage requirements to support different resource-intensive service offerings. Des...

This document defines an abstract architecture for Direct Data Placement (DDP) and Remote Direct Memory Access (RDMA) protocols to run on Internet Protocol-suite transports. This architecture does not necessarily reflect the proper way to implement such protocols, but is, rather, a descriptive tool for defining and understanding the protocols. DDP allows the efficient placement of data into buf...

When memory encryption schemes are applied in multiprocessor systems, the systems will confront new problems such as inter-processor communication overhead increasing and cache coherence protocol overhead increasing. A counter cache coherence optimization scheme AOW is proposed to improve cache hit rate. As MESI protocol which makes counter line by four states, AOW marks each counter line using...

We propose to enhance EPCglobal RFIDs enriching them with semantic capabilities. Memory organization of tags and the data exchange protocol are exploited and extended to the purpose. By design, the proposed enhancements do not alter the basic behavior of protocol and tag memory organization and are thus fully backward compatible. In order to store annotated descriptions a compression algorithm ...
