The strong growth of ruse machines, whose performance is more tightly coupled to the memory hierarchy, has created increasing demand for high performance memory systems. This trend is likely to accelerate: the
5. A multiprogramming operating system builds on this base, adding modules to manage processor time, main memory space, and peripheral devices. 6. In multiprogramming, the conditions under which low - priority programs are executed. 7. In some multiprogramming systems, a value used to define or...
Kernel lock spinning was reported to be a major component of MP overhead (causing well over one-third of the total system overhead) in the Cedar operating system running on Aliant multiprocessors =-=[S]-=-. Performance measurement on a UNIX kernel in a 6 processor system shows that ...
A multiprogramming system is described in which all activities are divided over a number of sequential processes. These sequential processes are placed at various hierarchical levels, in each of which one or more independent abstractions have been implemented. The hierarchical structure proved to be vit...
Several analytically solvable queueing models of multiprogramming with different jobs and various scheduling disciplines are investigated. It is shown that the analysis of these models supports the optimality of the already proposed CPU scheduling discipline which assigns higher processing priority to a more...
Operating System/Multiprogramming of Fixed Tasks (operating system) (OS/MFT) One of theIBMoperating systems associated with theIBM 360, released in 1966 and targetted at mid-rangeIBM 360users (typically 360/40, 360/50). OS/MFT was the juinior member of the main 'OS' series of IBM operat...
One important class of multiprocessing, multiprogramming systems is relational data base management systems. In a relational data base, data is perceived to exist in one or more tables. Each table consists of a specific number of columns and a number of unordered rows. Each column in a row is...
The strong growth of ruse machines, whose performance is more tightly coupled to the memory hierarchy, has created increasing demand for high performance memory systems. This trend is likely to accelerate: the improvements in main memory performance will be small compared to the improvements in ...
The basic concern of multiprogramming is concurrency of operations within computer systems. Many different types of concurrency are incorporated in the computers in use today. Multiprogramming is defined as the technology associated with the concurrent execution of instructions, which are not restricted to...
multiprogramming Thesaurus Medical Encyclopedia Wikipedia multiprogramming (ˌmʌltɪˈprəʊɡræmɪŋ) n (Computer Science) a time-sharing technique by which several computer programs are each run for a short period in rotation ...
