This paper presents the experiences made with the design and implementation of the Peace message-passing kernel. Peace is the object-oriented parallel operating system developed for the Manna parallel computer. Manna is a dual-processor-node distributed-memory machine using crossbar technology for node interconnection. Performance figures of the Peace kernel configurations are presented and their implications with respect to communication latency hiding are discussed.
