Tecnologia NOPL Erlang-Elixir: paradigma orientado a notificações via uma abordagem orientada a microatores assíncronos

Abstract

The multicore architecture consists of the implementation of multiple cores in the same chip, which is becoming an alternative to the stagnation of microprocessor speed rates. In theory, by increasing the number of parallel processing units, it is possible to improve execution performance. However, in practice, this depends on software designed specifically to explore such feature. This type of software development brings more difficulty when compared to the usual sequential programming. In this context, an alternative software development technique called Notification Oriented Paradigm (NOP) was proposed, which is based on minimal and collaborative notifying entities. NOP provides natural decoupling among its entities, which benefits the use of parallelism and distribution. In this environment, the NOPL was previously proposed, which is a high-level programming language for NOP and a corresponding compilation technology that assists compiler composition. This NOPL technology, however, is not platform-specific and needs to be properly applied to each target platform. That said, this M.Sc. Dissertation aims to present a NOP solution based on NOPL technology for multicore environments. In order to achieve this objective, an Elixir framework is first proposed, which reproduces each element of the NOP as an Erlang micro-actor. Subsequently, this framework is integrated to the NOPL technology. With this synergy of technologies, it is aimed to join the concurrency and balance of Erlang architecture with the implicit decoupling of NOP entities and the high-level programming provided by NOPL. Indeed, experiments performed on this proposed technology show considerable performance improvement as the number of cores increases, by keeping appropriate and balanced load percentages. As a result, the object of this research presents itself as a high-level multicore development platform that takes advantage of parallel processing cores in a transparent way for the developer.
