MU6V is a parallel vector processing system in which a linear set of processors, each capable of both vector and scalar operations, is interconnected by a common communication highway.Memory is fully distributed among the processors and interprocessor communication occurs by means of global broadcasts controlled in hardware by a data driven synchronization mechanism.A prototype model based on 68000 microprocessors, in which vector orders are emulated as "extracodes", has been constructed.A host machine provides a software support environment and a run-time system in the prototype provides diagnostic information.Programming language features have been designed to exploit this configuration and an example algorithm is presented.

Abstract Portability of MUSS compilers is achieved by using an abstract machine model concept. Two different abstract models, both suited for multi‐language multi‐machine usage, have been developed and evaluated. These models differ mainly in the level of interface to the compiler. The form of these models and the performance of two compilers, each using both models, are presented.

In this paper the design of the software implementation language for the MU5 machine is considered. This has two representations, the written language, MU5 Autocode, and the parametric compiler target language (CTL).

This paper describes a self expanding program generator aimed at the general area of system programming. A syntax directed scan is used for statement recognition. The set of statements is extended by additions to the syntax tables.
