Parallel computation is making a comeback after a quarter century of neglect. Past research can be put to quick use today.

Programming semantics for multiprogrammed computations
The semantics are defined for a number of meta-instructions which perform operations essential to the writing of programs in multiprogrammed computer systems. These meta-instructions relate to parallel processing, protection of separate computations, program debugging, and the sharing among users of memory segments and other computing objects, the names of which are hierarchically structured. The language sophistication contemplated is midway between an assembly language and an advanced algebraic language.

A multiuser computation facility for education and research
Present-day computing facilities are limited in their value for scientific research by inability to interact strongly with users. The full power of a research computing instrument should be available at many terminals that give each user the ability to generate, correct and operate any procedure he wishes, either simple or complex.
Implementation is described for a small-scale multiuser computer system that permits several users to work independently with the machine, and to obtain satisfactory response using typewriter communication.
