Aspects of Load Management on Parallel

This paper concentrates on load management methods for multiprocessor systems with distributed memory. Most of the programs running on these machines do not create new processes during runtime and there is usually no sharing of nodes between multiple users. This causes load movement by process migration to be indispensable. We implemented a testbed to nd out which load parameters are signiicant for deciding on a system rebalance. The testbed also allows the investigation of other important aspects of load management schemes. Considerable reductions in runtime were achieved for a variety of test programs.
