We present a new model for distributed shared memory systems, based on remote data accesses. Such features are offered by network interface cards that allow one-sided operations, remote direct memory access and OS bypass. This model leads to new interpretations of distributed algorithms allowing us to propose an innovative detection technique of race conditions only based on logical clocks. Ind...

Non-local spin injection in lateral spin valves generates a pure spin current which is a diffusive flow of spins (i.e. spin angular momentums) with no net charge flow. The diffusive spins lose phase coherency in precession while undergoing frequent collisions and these events lead to a broad distribution of the dwell time in a transport channel between the injector and the detector. Here we sho...

[1] We show that the spatial coherency of the ambient seismic field can be used for attenuation tomography in the western United States. We evaluate the real portion of the spatial coherency with an elastic geometric spreading term (a Bessel function) and a distance dependent decay (an attenuation coefficient). In order to invert the spatial coherency, a weight stack inversion technique is appl...

Intègre is a decision-support software specially designed for collective processes. Collecting all required information for decision making, Intègre harmonizes representations and processes collected data to check users’ decisions coherency. During their consultation, specialist doctors access to analysis’ results and to patients’ data, stored in their own databases or in administration’s syste...

Multiprocessor systems-on-chip (MPSoC) with distributed shared memory and caches are flexible when it comes to inter-processor communication but require an efficient memory consistency and cache coherency solution. In this paper we present a novel consistency model, streaming consistency, for the streaming domain in which tasks communicate through circular buffers. The model allows more reorder...

The integration of many cores per chip will lead to inefficiency of traditional multi-processor techniques. In particular, a hardware cache coherency protocol includes performance and hardware overhead, so that for a growing number of cores the coherence wall problem will become more serious. The Single-chip Cloud Computer (SCC) is a recent research processor of a Cluster-on-Chip architecture, ...

Scalable shared memory multiprocessors commonly employ replication and the associated coherency maintenance of memory blocks, but diier in the granularity from ne-grain (cache-coherent multiproces-sors) to coarse-grain (page-based distributed shared memory systems). Regardless of the size of coherency blocks, attaining good performance may depend on the number of copies staying small. Previous ...

If each phase has an identical crystal structure and small misfit in the lattice parameters in a binary-phase crystalline system, coherent phase boundaries usually form during separation. Although there have been numerous studies on the effect of coherency elastic energy, no attempt has been made to demonstrate how the phase-separation behaviour varies when multiple interfaces meet at a junctio...

A theoretical investigation of the effects of elastic coherency strain on the thermodynamics, kinetics, and morphology of intercalation in single LiFePO(4) nanoparticles yields new insights into this important battery material. Anisotropic elastic stiffness and misfit strains lead to the unexpected prediction that low-energy phase boundaries occur along {101} planes, while conflicting reports o...
