Prédiction de Performances pour les Communications Collectives
Résumé Des travaux récents visent l’optimisation des opérations de communication collective dans les environnements de type grille de calcul. La solution la plus répandue est la séparation des communications internes et externes à chaque grappe, mais cela n’exclut pas le découpage des communications en plusieurs couches, pratique efficace démontrée par Karonis et al. [10]. Dans les deux cas, la...
متن کاملIntentional Collectives
This paper gives an upside-down view of the problem of collective intentionality by providing a treatment of the notion of intentional collective. Based on reviews of the relevant literature, we apply three formal-ontological tools of our choice (namely, DOLCE, D&S, and DDPO) to the definition of the notions of collection, agent, plan and collective, all underlying the concept of intentional co...
متن کاملGenerative Collectives
Analyzing generative group activities against the backdrop of an increasingly connected world, this theory development paper introduces the concept of "generative collectives" as a new framework for classifying internet-based collectives and a novel theoretical lens for explaining why some internet-based groups are more generative than others. Generative collectives are groups of people with sh...
متن کاملUnpredictable strings are collectives
In [Z] we defined the notion of an “inference method” which given a finite binary string guesses its continuation. We showed that a special class of these inference methods could be used to construct a very general theory of confirmation. In this paper we investigate the class of strings which are unpredictable with respect to these inference method-that is, infinite strings which are such that...
متن کاملMPI collectives at scale
Collective operations improve the performance and reduce code complexity of many applications parallelized with the messagepassing interface (MPI) paradigm. In this article, we will investigate the impact of load imbalance on the performance of collective operations and possibility for hiding parallel overhead caused by a collective communication pattern, by overlapping the communication with c...
