Título: A unified MapReduce programming interface for multi-core and distributed architectures
In order to improve performance, simplicity and scalability of large
datasets processing, Google proposed the MapReduce parallel pattern.
This pattern has been implemented in several ways for different
architectural levels, achieving significant results for high performance
However, developing optimized code with those solutions
requires specialized knowledge in each framework's interface and
programming language. Recently, the DSL-POPP was proposed as a framework
with a high-level language for patterns-oriented parallel programming,
aimed at abstracting complexities of parallel and distributed code.
on DSL-POPP, this work proposes the implementation of a unified
MapReduce programming interface with rules for code transformation to
optimized solutions for shared-memory multi-core and distributed
architectures. The evaluation demonstrates that the proposed interface
is able to avoid performance losses, while also achieving a code and a
development cost reduction from 41.84\% to 96.48\%. Moreover, the
construction of the code generator, the compatibility with other
MapReduce solutions and the extension of DSL-POPP with the MapReduce
pattern are proposed as future work.
