Dynamic grain-size adaptation on object oriented parallel programming the SCOOPP approach

This paper presents the SCOOPP (SCalable Object Oriented Parallel Programming) approach to support the design and execution of scalable parallel applications. The SCOOPP programming model aims the portability, dynamic scalability and efficiency of parallel applications. The SCOOPP is an hybrid compile and run-time system, which can perform parallelism extraction, supports explicit parallelism and performs dynamic granularity control at run-time. The mechanism that supports dynamic grain-size adaptation is presented and performance evaluated on two parallel systems. The measured results show the feasibility of the proposed dynamic grain-size adaptation and a scalability improvement of parallel applications over static parallel OO environments, which suggests cost benefits to develop scalable parallel applications to run on multiple platforms 1
