The most commonly encountered skeletons are pipelines and variants of the common list-processing functions map, scan and fold. We use algorithmic skeletons to partially achieve this goal. Similarly, the collections of computation and reorganization skeletons could be extended. We build upon this approach, and provide two new collections of skeletons to the programmer: the communication skeletons and the mask skeletons. Nevertheless, the compilation schemes described in section 3 can be adapted to spmd skeletons almost straightforwardly. The skeletons of non-photosymbiotic corals appear to show no isotopic fractionation, and so faithfully record sea-water temperature changes. Figure 1 depicts the skeletons we present in this paper, and their dependences. Ignoring the scalar code between the two spmd skeletons makes them perfect candidates for merging. To ensure the affinity of cost expressions, conditionals are constrained to be mask skeletons whose condition characterizes a convex polytope. Another important restriction is that expressions involving iteration indexes (mask skeletons, communication skeletons and iterfor bounds) are affine. The four reorganization skeletons are zip, unzip, makearray and append. Their skeletons are less restricted than ours leading to an approximate parallel cost (communication or/and computation). They make it possible to describe highlevel languages enjoying important properties without preventing further extensions (by adding new skeletons). In our approach, the analysis takes into account both load balancing and communication costs, since the collective communications appear explicitly through communication skeletons. Evidence of malignant neoplasm is extremely rare in antiquity, judging from the thousands of skeletons and mummies which have been examined. The objects and associated skeletons were literally raised above the ground. Design and synthesis of synchronization skeletons using branching time temporal logic. Apart from the oval clay objects, no artefacts could be directly associated with these skeletons on the roof. To this extent we have advanced the concept of algorithmic skeletons into a practical and usable tool. No vague abstraction legible only to a privileged few, the looming skeletons of extinct beasts were terrifyingly proximate to an increasingly fragile present. Plan skeletons are thus well suited to serve as a mediator language between the user and the system. I repor t strontium isotope ratios obtained from the teeth of four of these skeletons. Moreover, the data for teeth from the peripheral skeletons indicate that they were also local children. What can explain the death of great numbers of lepidosaurs and other small tetrapods that are transported as articulated skeletons and/or numerous individual bones? The only in situ materials were the articulated skeletons on each side of the access stair. A greater concentration of objects near the access to the chamber and between the skeletons was noted. After a spontaneous awakening, the man reported a dream in which he was running and trying to escape skeletons that were awaiting him. In particular, the new versions of communication skeletons express the same data motions as before, but on the vector of processors. There are seven communication skeletons which describe families of data motion within vectors. No significant sequential or parallel runtime penalty seems to result from programming using skeletons, at least for such regular algorithms. First, the combination of such distributions and the polyn skeletons gives rise to expressions whose cost cannot be expressed as polytopes. The rules for other skeletons are similar, and the rules for subtyping are the usual ones. In practice, there are strong constraints upon which types of functions can be used as skeletons. Special emphasis is given to divide-and-conquer skeletons, for which several variants are provided. Furthermore, the programmer is at liberty to define and implement new skeletons. As well as genericity, skeletons offer a number of other advantages. The ptr and ptorus skeletons briefly described above make use of this facility. The rules can be viewed as acting on skeletons to 'order' them (what we call normal skeletons should be seen as completely 'ordered' structures). However, it is also possible to combine skeletons with imperative approaches. In the following example, we illustrate graph skeletons for a specific kind of graph. The two morphisms will be rule skeletons and the relations will model the gluing of skeletons along common elements. In addition to these fossils, there were four chests of skeletons of extant species for comparison with their fossil analogues. The analysis concentrates on bones from datable contexts, so it is possible that information on neonate skeletons from non-datable contexts has been lost. I believe that they belong to the same two skeletons, from which only a few teeth were expor ted for study, for whatever reason. The four skeletons that occupy the central part of the chamber were apparently not placed at the same time. Moving nor thward, excavation began to uncover the central cluster of skeletons, including the extended supine principal occupant of the tomb. Their caskets are more ornate and only portions of the two flanking skeletons are visible. Several of the skeletons hold small scythes, and one contemplates a skull. No grave goods were found in association with the skeletons. In this period they discovered a variety of other items including blue cloth from a naval uniform, and the bones of several skeletons. Their fossil remnants show morphological features uniquely characteristic of life and hence their documentary value is comparable to animal skeletons on a microscopic scale. In fact, control abstractions could be seen as an efficient implementation technique for algorithmic skeletons. Much research into skeletons has been directed towards automated derivations of specific classes of problems. The communication skeletons considered are standard collective communication primitives (broadcast, translation, etc.) which are either hard-wired or optimized on many parallel machines. Communication skeletons (such as pbrdcast) will be implemented as calls to a standard communication library. The only differences lie in the arguments of mask skeletons and new versions of communication and reorganization skeletons. The algorithmic skeletons approach, however, is not restricted in this way, and could decide between such implementations based on suitable performance models. Within this framework skeletons such as parallel map and fold can be defined but the application of such skeletons is controlled explicitly by the programmer. Rigid external or internal skeletons would prevent the curling. The skeletons and data structures have been chosen with scientific computing in mind. Before introducing coordinated rules, we need the notion of commutativity for certain diagrams containing two partial morphisms and two relations between graph skeletons. Finally, a few skeletons remain in the closet. The intact skeletons provide prima facie evidence that the animals were not predated. All missing individuals were recovered as intact, fully articulated skeletons. Approaches based on accommodating skeletons in existing languages have proved more popular, especially where such languages are used as a coordination layer for skeletons. In addition, skeletons are suitable for both regular and irregular parallel applications. In section 2, the skeletons dc0 to dc3 are defined. There are two approaches to realising skeletons in functional languages. Several skeletons are provided, including map, red (fold), filter and scan. Here, co-ordination is carried out using a dataflow model and skeletons such as task farm and data farm are provided. Therefore, in our opinion, the best minimum set of skeletons is the one which is required to introduce and control parallelism in the host language. Seedlings that were intact or retained some green foliage were scored as alive; seedlings scored as dead were missing or present as dry skeletons. Similar patterns were observed when we examined the children's ability to represent the items' phonological skeletons. The first phase star ts with defining a component type hierarchy on the basis of the process type hierarchy used in modeling plan skeletons. Plan skeletons seem to be expressive enough for representing even complex process structures of product families with many variants. The list of possible knowledge categories used for modeling plan skeletons also has no clear limits. Not all of the seven knowledge categories are needed for modeling process configuration knowledge with plan skeletons. Although there are animal bones, there are no ar ticulated skeletons suggestive of deliberate burial. The sealed cist contained burned and unburned fragments of at least two human skeletons and pot sherds. Over forty skeletons of children and adults were found in the shaft of this temple, along with much charcoal and ash. On these sites isolated human bones, as well as complete human skeletons and complete animal carcasses, usually elk or aurochs, were deposited. There is also a degree of ambiguity about the exact position of the skeletons that it might have been useful to see clarified. As already mentioned, no bodies (victims of hostilities) have been found inside the buildings (apart from the two skeletons). Second, as has been suggested, our two skeletons may have been persons of some social importance. However, a number of samples lie far from this mean and are presumably skeletons of individuals born elsewhere. Among these teeth are two that may belong to adult skeletons. Different categories of process-planning knowledge are modeled in plan skeletons and the associated process type hierarchy. Future discoveries of relatively complete hominin skeletons are needed to address this question. Such proof skeletons contain "holes" corresponding to logical propositions not unlike our constraint formulas. We define there the skeletons as certain structures of and operators. At present this identifies our base skeletons using pattern matching: we would like to implement more sophisticated transformations for exposing and optimizing parallelism. Also, the island should have contained many noteworthy skeletons. Provided a sufficient number of skeletons and their equivalent implementations are available, any parallel architecture can be treated in this way. Based on this information a cost model for the available skeletons, possibly nested, is used to select a decomposition and mapping of parallel threads.
