Group P-9 at the Los Alamos Scientific Laboratory has three MODCOMP IV/25 computers. The configuration consists of a host computer and two satellite computers. It was decided to implement an intercommunication system using the shared memory feature of the system and symbionts. With this symbiont approach all MAX IV file I/O operations using REX services are supported. The operation of this system is described in some detail. Among the topics covered are system initialization, common block structure, resources of the tasks, error conditions, limitations, and speed. 6 figures. (RWR)
