Despite important advances in Grid computing, scalability and interoperability issues obstruct the integration of the existing isolated grids into the Grid. We propose a worldwide ...
We consider the realization of matrix-matrix multiplication and propose a hierarchical algorithm implemented in a task-parallel way using multiprocessor tasks on distributed memory...
Security is an important concern in providing the infrastructure for the implementation of general purpose computational grids. However, most grid implementations focus their secu...
In this paper we argue for middleware languages that aid in service composition. We outline where such languages could be useful through the description of our current architectur...
This paper presents an MPI implementation that allows an easy and efficient use of the interconnection of several clusters, of potentially heterogeneous nature (as far as the net...
