One click cloud orchestrator: Bringing complex applications effortlessly to the clouds

© Springer International Publishing Switzerland 2014.Infrastructure cloud systems offer basic functionalities only for managing complex virtual infrastructures. These functionalities demand low-level understanding of applications and their infrastructural needs. Recent research has identified several techniques aimed at enabling the semi-automated management and using applications that span across multiple virtual machines. Even with these efforts however, a truly flexible and end-user oriented approach is missing. This paper presents the One Click Cloud Orchestrator that not only allows higher level of automated infrastructure management than it was possible before, but it also allows end-users to focus on their computational problems instead of the complex cloud infrastructures needed for their execution. To accomplish these goals the paper reveals the novel building blocks of our new orchestrator from the components closely related to infrastructure cloud to the ways virtual infrastructures are modeled. Finally, we show our initial evaluation and study on how the orchestrator fulfills the high level requirements of end-users

PIPELINED EXECUTION IN MULTI-USER SEQUENTIAL RECURSIVE LOOPS

Recursive sections in a data path are constraints to the minimum value of data introduction latency (R) in that data path. Minimizing loop execution times is a way to increase the virtual data introduction frequency (1/ R), with the minimum values set by the loops themselves. For a number of applications, another method is possible to decrease the restart time while actually increasing the total execution time of the loop (Lr). An advantage of this method is that the increase of execution time is an external constraint. This paper presents a description of such problems, with the steps of scheduling performed for an application of this type

Struttura epistolare di alcune lettere di Stato di Coluccio Salutati

The aim of this paper is to present the structure and construction of some state letters written in 1375 by the Florentine chancellor Coluccio Salutati, with a brief reference to their content. I examine whether the theme and type of the letter affect the internal structure of the letter and, if so, to what extent and in what way. The classical structure of the letter – salutatio, captatio benevolentiae, narratio, petitio, and conclusio – was generally reduced to three parts in medieval missilis practice. At the time of Salutati this process had not yet ended, so sometimes the classic parts are confused with each other, but it is not rare to find units well separated in the letters. I examined these units in my corpus, which contains twenty-five letters written in Latin
