This document describes the prototype developed during the first year of the project. The features of this prototype, called PPC are based on our experience in a previous tool called “Avispa” developed for a particular multiprocessor and a particular problem (iterative methods for sparse systems). Some new functionalities that are specific for Grid environments as well as other kernels are also implemented in this prototype, and will be added in future versions. We developed the prototype for the matrix-vector product and other kernels of sparse matrix algebra, as well as for the vertlq routine extracted from one of the applications of task 1.4.
