NOSY: A Core-saving Operating System.
ResearchPublished 1967
A revision of P-3168 to reflect the change in Rand's computer system from an IBM 7040 coupled to a 7044, to the 7044 alone. This paper describes the NOSY (NonSYS) software for use with programs that exceed available storage on the 7044. Converting codes from FORTRAN II to FORTRAN IV causes loss of core storage, because the IV compiler in most cases produces more instruction words than the II compiler, and because the IBSYS nucleus requires so much storage space. The NOSY method eliminates the nucleus during execution, thus releasing core storage at the cost of less efficient input/output. It was devised originally for a Rand two-dimensional hydrodynamic model that continued to exceed available storage even when a chaining procedure was used. 12 pp.
