Contoh skeleton

• 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.
