Abstract:
 In other papers I propose the idea of disk-directed I/O for
 multiprocessor file systems.  Those papers focus on the performance
 advantages and capabilities of disk-directed I/O, but say little about
 the application-programmer's interface or about the interface between
 the compute processors and I/O processors.  In this short note I
 discuss the requirements for these interfaces, and look at many
 existing interfaces for parallel file systems.  I conclude that many
 of the existing interfaces could be adapted for use in a disk-directed
 I/O system.
