A Wide Area Network cluster consisting of 5 UNIX-type machines of different architectures and different operating systems is set up via PVM 3.4.3. The 5 nodes are distributed over 4 European research centres located in France, Italy and Austria and only secure shell-type internode communication is allowed.The recently developed concept of Speed Weighted Load Balancing is employed when using GREMLIN - a Quantum Chmistry program - for the electronic structure calculation of alanine.In contrast to the previous static concept, a new dynamic functionality is added, that allows for runtime re-equilibration of all the participating hosts.Ev en complicated events, such as crash down of contributing hosts may be adressed from this new, dynamic, version of Speed Weighted Load Balancing, without the loss of intermediary data, or a considerable deviation from optimal host performance.
