Large core storage utilization in theory and in practice

Abstract

Amid the rapid growth of the computer industry and its attendant expansion of capability, it is relatively easy for the industry to overlook items of potentially vast significance. One such item, mass storage, has been used since 1963 for job shop support, as well as for real time support, of manned space exploration. These applications have shown that mass storage can dramatically reduce requirements for main storage and at the same time improve system performance. This paper relates theoretical software implications of mass storage, in particular the LCS, as used to benefit the Manned Spacecraft Center in Houston, Texas. Here, the IBM Federal Systems Division holds a contract with the NASA to provide real time ground support for manned space exploration.
