Book excerpt: Abstract: "Most parallel object oriented languages (OOL) are currently using a general parallelism model based on communicating sequential processes. This approach makes it difficult to program massively parallel systems in an easy and efficient way. So we propose to use another form of parallelism, known as data parallelism. We describe how a sequential OOL can embed data parallelism in a clean and elegant fashion -- without language extensions -- in order to exploit the potential power of massively parallel systems. Then we present EPEE (an Eiffel Parallel Execution Environment) at work with a well known parallel paradigm (matrix computations), along with experimental performance results. We draw some conclusions on the generality of this approach."

Available in PDF, EPUB and Kindle. Book excerpt: Pour faciliter l'introduction du parallélisme, il a été défini un message à destinataires multiples, adaptable à tout langage objet, possédant un ensemble de propriétés défini. Ce mode communication s'appuie sur deux objets complémentaires: le filtre qui définit l'ensemble des destinataires et le routeur qui assure l'acheminement du message vers ceux-ci. Filtres et routeurs sont des objets adaptables et utilisables indépendamment les uns des autres. Les filtres définis ont été implantes en Small talk 80 et leur impact sur la modularité et la souplesse des objets a été mesurée sur un simulateur de circuits logiques

Book excerpt: Le travail presente dans cette these consiste a definir les fonctionnalites d'une machine virtuelle ParObj, supportant la notion d'objets concurrents et adaptee aux exigences du parallelisme massifs. Cette these s'inscrit dans le cadre du projet PARX de l'equipe "SYstemes Massivement PAralleles" du LGI qui vise a specifier et a realiser un systeme d'exploitation pour machines paralleles. A travers l'analyse de quelques Systemes Distribues a Objets connus, nous degageons les mecanismes de base que doit supporter ParObj. Nous avons arrete notre etude sur les aspects suivants : structures des entites, gestion des entites, gestion des interactions entre entites, et gestion des ressources. Dans notre approche, nous offrons dans ParObj un support parallele pour des objets passifs et actifs qui peuvent etre a la fois a gros grains (fichier, processus, etc.), et a grains intermediaires (liste chainee, thread, etc.). Pour une gestion encore plus fine du parallelisme, nous supportons aussi la notion d'objet fragmente. Un objet fragmente est un objet qui est decoupe en plusieurs sous-objets independants (fragments de l'objet) de taille quelconque, et qui peuvent etre accedes individuellement, de maniere concurrente.En revanche, nous avons decide de laisser aux compilateurs le soin de gerer les objets a grains fins. De plus, pour eliminer les conflits d'acces aux donnees, nous offrons un mecanisme de synchronisation des objets. L'architecture generale de ParObj est basee sur le modele original a trois niveaux de processus de PARX : le thread (qui est un flot de controle sequentiel a l'interieur d'une tache), la tache (qui est un contexte d'execution), et la Ptache (qui represente un programme parallele a l'execution). Une Ptache definit un domaine de communication et de protection, et assure la correction semantique du programme parallele (synchronisation des taches, controle des protocoles d'echanges, etc.). Au sein d'une Ptache, la protection des objets est assuree grace a des capacites. La localisation d'une entite (qui depend de sa visibilite et de sa reference) est realise grace a un mecanisme original de designation. Les experimentations que nous avons realisees montrent que ce mecanisme est parfaitement adapte a la gestion du parallelisme massif.

Download or read book Divagations written by StŽphane MallarmŽ and published by Harvard University Press. This book was released on 2009-06-15 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is a book just the way I don't like them," the father of French Symbolism, StŽphane MallarmŽ, informs the reader in his preface to Divagations: "scattered and with no architecture." On the heels of this caveat, MallarmŽ's diverting, discursive, and gorgeously disordered 1897 masterpiece tumbles forth--and proves itself to be just the sort of book his readers like most. The salmagundi of prose poems, prose-poetic musings, criticism, and reflections that is Divagations has long been considered a treasure trove by students of aesthetics and modern poetry. If MallarmŽ captured the tone and very feel of fin-de-sicle Paris, he went on to captivate the minds of the greatest writers of the twentieth century--from ValŽry and Eliot to Paul de Man and Jacques Derrida. This was the only book of prose he published in his lifetime and, in a new translation by Barbara Johnson, is now available for the first time in English as MallarmŽ arranged it. The result is an entrancing work through which a notoriously difficult-to-translate voice shines in all of its languor and musicality. Whether contemplating the poetry of Tennyson, the possibilities of language, a masturbating priest, or the transporting power of dance, MallarmŽ remains a fascinating companion--charming, opinionated, and pedantic by turns. As an expression of the Symbolist movement and as a contribution to literary studies, Divagations is vitally important. But it is also, in Johnson's masterful translation, endlessly mesmerizing.

Download or read book What Are Philosophical Systems written by Jules Vuillemin and published by Cambridge University Press. This book was released on 1986-07-31 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a learned and ingenious attempt to understand the origin and nature of philosophical inquiry. It draws on material from numerous disciplines and from all periods of philosophy and provides challenging arguments on a wide range of topics. The author constructs a hierarchy of ontological claims, beginning with perceptual experience, moving to language and science. He traces subtle and unexpected relations among these and concludes by offering a system for classifying philosophical theories which reveals why they take the form they do and why philosophical dispute is ineradicable. The book offers many fresh insights into such topics as the nature of experience, the nature of language and that of philosophy itself. It will interest a wide range of philosophers, in particular those concerned with categorical schemes, grammar and ontology.

Download or read book On Logic and the Theory of Science written by Jean Cavailles and published by MIT Press. This book was released on 2021-04-27 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new translation of the final work of French philosopher Jean Cavaillès. In this short, dense essay, Jean Cavaillès evaluates philosophical efforts to determine the origin—logical or ontological—of scientific thought, arguing that, rather than seeking to found science in original intentional acts, a priori meanings, or foundational logical relations, any adequate theory must involve a history of the concept. Cavaillès insists on a historical epistemology that is conceptual rather than phenomenological, and a logic that is dialectical rather than transcendental. His famous call (cited by Foucault) to abandon "a philosophy of consciousness" for "a philosophy of the concept" was crucial in displacing the focus of philosophical enquiry from aprioristic foundations toward structural historical shifts in the conceptual fabric. This new translation of Cavaillès's final work, written in 1942 during his imprisonment for Resistance activities, presents an opportunity to reencounter an original and lucid thinker. Cavaillès's subtle adjudication between positivistic claims that science has no need of philosophy, and philosophers' obstinate disregard for actual scientific events, speaks to a dilemma that remains pertinent for us today. His affirmation of the authority of scientific thinking combined with his commitment to conceptual creation yields a radical defense of the freedom of thought and the possibility of the new.

Download or read book Advanced French Grammar written by Monique L'Huillier and published by Cambridge University Press. This book was released on 1999-06-17 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1999 reference grammar, written for advanced students of French, their teachers, and others who want a better understanding of the French language, combines the best of modern and traditional approaches. Its objective is not only practical mastery of the language, but familiarity with its structure. Taking into account modern linguistic research, Advanced French Grammar approaches the French language primarily through the study of syntactic structures, but without excessive emphasis on formalism. It provides a generous number of examples, based on the author's own experience of teaching French to English-speakers, to help the student to understand the different meanings of apparently similar syntactic alternatives. The norms of 'correct expression' are given together with current usage and deviations, and appendixes provide information on the 1990 spelling reforms and on numbers. A substantial index of French and English words and of topics provides easy access to the text itself.
