METACOMPUTING IN GIGABIT ENVIRONMENTS - NETWORKS, TOOLS, AND APPLICATIONS

This article gives an overview over recent and current metacomputing a ctivities of the Computing Centers at the Forschungszentrum Julich, th e GMD Forschungszentrum Informationstechnik and the University of Stut tgart. It starts with a discussion of the underlying network connectio ns which are dedicated testbeds. A library that provides an MPI-API fo r metacomputing applications is presented, as well as a library that s upports load-balancing and latency hiding, Finally, results from sever al applications ranging from tightly coupled homogeneous to loosely co upled heterogeneous metacomputing are presented.
