Abstract

This paper introduces the input/output facilities of DPPX, the Distributed Processing Programming Executive for the IBM 8100 Information Processing System. Design requirements and alternatives are discussed, as well as the general structure of the services that implement the I/O facilities. Services that support specific I/O resources, such as disk storage and communication devices, are related to the general structure. The paper considers some of the problems in designing a general structure to support a wide range of services, and it briefly describes the interface architecture used to solve these problems.
