This volume contains revised versions of the 23 regular papers presented at the First International Workshop on Parallel Computer Routing and Communication (PCRCW '94), held in Seattle, Washington in May 1994. Routing for parallel computer communication has recently experienced almost explosive activity: ever increasing processor speeds are placing greater demands on interprocessor communication, while technological advances offer new capabilities to respond to those demands. The contributions from industry and academia cover all areas, from details of hardware design to proofs of theoretical results. There are also many papers dealing with the performance of various adaptive routing schemes, new network topologies, network interfaces, and fault-tolerant issues.
