Distributed symbolic computations involve the existence of remote references allowing an object, local to a processor, designate another object located on processor. To reclaim inaccessible objects is non trivial task distributed Garbage Collector (GC). We present in this paper new GC algorithm which (i) fault-tolerant, (ii) largely independent how processor garbage collects its own data space, (iii) does not need centralized control nor global stop-the-world synchronization, (iv) allows for...

This paper argues that algorithmic skeletons are a suitable programming model for multi-core architectures. The high-level abstractions offered by provide simple way non-parallel programmers to address parallel programming. Previous skeleton frameworks and libraries have addressed distributed computing environments such as Clusters Grids. proposes library, Skandium; concludes, after an experimental evaluation, effective methodology program

Abstract Porphyry-type deposits are the main global source of copper and molybdenum. An improved understanding most favorable structural settings for emplacement these is necessary successful exploration, particularly considering that future discoveries will be made under cover based on conceptual target generation. A common view porphyry preferentially emplaced in pull-apart basins within strike-slip fault systems favor local extension a regional compressive to transpressive tectonic...

Abstract In the central Andes, giant porphyry copper deposits of similar ages group into discrete geographic clusters that are regularly spaced and aligned within orogen-parallel belts. This clustering highlights how exceptional geologic processes affected localized regions lithosphere during mineralization spatial temporal distribution is nonrandom. Development favorable for significant metal concentration linked to overlap structural pathways focus fluid magma flow from mantle upper crust...

Long-lived, high-angle fault systems constitute high-permeability zones that can localize the upward flow of hydrothermal fluids and magma throughout upper crust. Intersections these types structures develop complex interference patterns, which volumes damaged rock (networks small-scale faults fractures) where permeability may be significantly enhanced. This is relevant for understanding regional-scale structural controls on emplacement mineral deposits volcanic centers, also distribution...

Abstract. Lithospheric-scale fault systems control the large-scale permeability in Earth's crust and lithospheric mantle, its proper recognition is fundamental to understand geometry distribution of mineral deposits, volcanic plutonic complexes geothermal systems. However, their manifestations at current surface can be very subtle, as many cases they are oriented oblique continental margin axis magmatic arc; partially obliterated by younger, arc-parallel faults; also covered sedimentary...

In a subduction setting, the type of magmatic products which reach upper crust, and eventually surface, depends on several variables, among some most relevant are tectonic regime, orientation magma pathways relative to predominant stress tensor. To better understand this relationship, we studied in detail an area Andes southern Central Chile subduction-related magmatism has been active at least during last 18 m.y. The relationship between high-angle faults was studied, spatiotemporal...

In new distributed systems, object mobility is usually allowed and sometimes used by the underlying manager system to benefit from access locality. On other hand, in-transit references objects can exist at any moment in asynchronous systems. presence of references, many garbage collector (GC) algorithms fail operate correctly. Others need use system's finder find while performing their work. As a general principle, GC should never interfere with polices (such as forcing migration or fixing...

Using this relation, defining an order processors, we describe our object balance algorithm as algorithm, focusing minimizing time when are...

Java mobile object systems generally rely on RMI (Remote Method Invocation) to transmit objects between remote sites. As a consequence, the semantics of parameter passing and value returning is restricted choices made by, designers RMI. Nevertheless, some applications require more adaptability in this regard. Resources (i.e., passive objects) may need be transferred using particular strategy depending not only their type (like statically permits), but also possibly application-specific...
