They identify two types of file access: one where the file can be operated on as a set of subfiles, each independently by a processor (what they call MIMD mode), and another where the file must be operated on with a centralized control (SIMD mode), in their case to search a B-tree whose nodes span the set of processors. Basically it is a host connected to a controller, that is connected to a set of small I/O processors, each of which has access to disk. In many ways a uniprocessor perspective. Paper design, with simulation results.} }
