摘要: Dynamic load balancing can improve the performance of a parallel application signi cantly. This is needed in the PVM environment because di erent nodes in the network have di erent processing capacities, networks have di erent data carrying capacities, in a timesharing environment, other users' processes can slow down a particular task in a parallel application. Also a large number of data parallel algorithms require unequal processing times for each quantum of data given to the processor. This paper explains the design and implementation of one such load balancing scheme under PVM. PVM is fast becoming a popular parallel programming environment both on a network of workstations, multiprocessors and other parallel and vector platforms.
