    An Evaluation of PC-based Modula-2 Compilers
    (1990) Fellows, David, M.
    The purpose of this study was to recommend a Modula-2 compiler to be used by students taking our introductory programming courses, CS1013 and CS1035 which are "Introduction to Computer Science" courses, and also for subsequent courses in data structures, etc. Computing support for these courses will be provided by diskless IBM PCs ("classics") each with 640 k of RAM and connected to a file server running the JANET network system. The network hardware is a 2 mbyte/sec network. Some students will have their own PCs and will want to use them. In this environment students spend most of their time editing, compiling and diagnosing small (10-1000 line) programs. As soon as they get the programs working they throw them away. Fast compilation, good error diagnostics and robustness, and convenient editing were the prime factors considered in this evaluation.

    Automatic job scheduling in hasp
    (1977) Gujar, Uday, G.; Fellows, David, M.
    Multiprogramming systems require that a fair, equitable algorithm be used for the scheduling of jobs. This paper discusses some of the problems associated with this and proposes an automatic job scheduling algorithm. The major parts of the algorithm have been implemented and have been in use for over one year. The user interface is simplified and the operational complexities are minimized. The parameters used for the algorithm are the estimates of the central processor time and the memory required by the job. All types of jobs including those requiring operator attention during execution are covered under the scheme. Operational data and the reactions from the users indicate that the results have been as expected.
