Abstract

The Gigabit Testbed West is a testbed for the planned upgrade of the German Scientic Network B-WiN. It is based on a 2.4 Gigabit/second ATM connection between the Research Centre Jülich and the GMD - National Research Center for Information Technology in Sankt Augustin. This contribution reports on those activities in the testbed that are related to metacomputing. It starts with a discussion of the IP connectivity of the supercomputers in the testbed. The achieved performance is compared with MetaMPI, an MPI library that is tuned for the use in metacomputing environments with high-speed networks. Applications using this library are briefly described.
