    Increasing speed and size demands on computer systems have resulted in corresponding demands on storage systems. Since it has been generally recognized that the speed and capacity requirements of storage systems cannot be fulfilled at an acceptable costperformance level within any single technology, storage hierarchies that use a variety of technologies have been investigated.

    In computing systems, it is a common occurrence for the execution of a program to result in the concurrent processing of several related input files. A set of input files is considered related when at least one unprocessed record from each file must be present in memory before the program can proceed. In this paper, we discuss the effect of floating buffering on the total time required for executi... View full abstract»

    The graphic simulation system discussed in this paper has been used extensively in support of the Apollo 8, 9, 10, 11, and 12 flight program developments, and it has met all design objectives. By providing a new dimension of program visibility and man-computer interaction, the system has had the effect of stimulating higher levels of interest and creativity by flight analysts.
