The finite element machine (FEM) is an experimental parallel computer consisting of an array of 36 asynchronous microcomputers. One method of interprocessor communication of FEM is a bi-directional parallel bus which uses a dynamic arbitration scheme to increase bus bandwidth. Testing of this bus revealed an imbalance in transfer rates for individual processors. The imbalance was traced to a defect in arbiter design, and two criteria were identified which must be met to ensure fair dynamic arbitration. These involve (1) priority sequencing, and (2) the efficiency of the arbiter. 3 references.
