An approach to systemsprogramming of mini- and micro-computersystems is described that utilizes a high-level language preprocessed into an intermediate form for interpretive language implementations. An ″Interpretive Optimization″ procedure is demonstrated which speeds up execution significantly by first determining a program's critical segments and then hand coding that segment in assembler.

This article discusses how to use a typical multi-programming operating system as is available on a number of the mini-computersystems currently in use. Particular system happens to have a primitive sort of duty cycle calculator built in the operating system which calculates the duty cycle for the last second and stores the current and maximum value experienced since system initialization.

National Software Works (NSW) is a DOD research and development effort designed to provide a software programming environment through the use of computer netting. While there are a number of software technical and managerial considerations, the issues are more complex when the concept of NSW is extended to cover both DOD programmers and government contractors. For example, this approach can provide a ″cradle to grave″ programming environment from the contractual development of a software system through the maintenance of that system by DOD personnel. Issues such as data rights, cost implications, and regulatory matters surround such a use. If the concept is applied to the general economic market place, the issues become even more challenging.

A description is given of DAPHNE, a system of tools and run-time support routines that allow programs to be broken into parts for distributed execution on different nodes of a heterogeneous computer network. This approach serves as a natural basis for classical network services such as remote file access or remote login while at the same time allowing arbitrary distributed applications to be written in a standard programming language. The pivot of DAPHNE is a remote procedure call mechanism that is specifically adapted to a heterogeneous environment, notably heterogeneous systems software. The current language context of DAPHNE is Modula-2. Prototype software exists for a local area network including Unix and MS-DOS systems.

This paper describes an implementation and performance evaluation of file replication in a locally distributed system. Different mechanisms are used to update the copies of a replicated file. The algorithms use both sequential and concurrent update methods. When updating the files sequentially, the algorithm is executed on the host on which the file has been written. Concurrent update is executed by using one machine or by using all the remote machines on which the file is replicated. The algorithms are proposed to update the copies of the replicated file by using various methods. These algorithms are implemented in a locally distributed system. The performance of the algorithms is compared for different loads and various read and write accesses to the files.
