COMP Superscalar: Bringing GRID Superscalar and GCM Together

This paper presents the design, implementation and evaluation of COMP Superscalar, a new and componentised version of the GRID superscalar framework that enables the easy development of Grid-unaware applications. By means of a simple programming model, COMP Superscalar keeps the Grid as transparent as possible to the programmer. Moreover, the performance of the applications is optimized by exploiting their inherent concurrency when executing them on the Grid. The runtime of COMP Superscalar has been designed to follow the Grid Component Model (GCM) and is therefore formed by several components, each one encapsulating a given functionality identified in GRID superscalar.
