RTLinux with Address Spaces
The combination of a real-time executive and an off-the-shelf time-sharing operating system has the potential of providing both predictability and the comfort of a large application base. To isolate the real-time section from a significant class of faults in the (ever-growing) time-sharing operating system, address spaces can be used to encapsulate the time-sharing subsystem. However, in practi...
متن کاملA Theory of Partitioned Global Address Spaces
Partitioned global address space (PGAS) is a parallel programming model for the development of high-performance applications on clusters. It provides a global address space partitioned among the cluster nodes, and is supported in programming languages like C, C++, and Fortran by means of APIs. Our first contribution is a formal model for the semantics of single program, multiple data programs t...
متن کاملThe grand unified theory of address spaces
A key decision in the design of an operating system is which facilities to provide for the management and composition of the address space. A wide spectrum of schemes exist, ranging from the private process address spaces of Unix through to the recently revived single address space approach. This paper proposes a new model which provides a unified and generalised approach to address space manag...
متن کاملWide Scattered Spaces and Morasses
We show that it is relatively consistent with ZFC that 2ω is arbitrarily large and every sequence s = 〈sα : α < ω2〉 of infinite cardinals with sα ≤ 2ω is the cardinal sequence of some locally compact scattered space.
متن کاملAddress spaces and virtual memory: specification, implementation, and correctness
In modern operating systems tasks operate concurrently on a logical memory. Address spaces control access rights to and the sharing of that memory. They are associated with tasks and manipulated dynamically by memory management operations of the operating system. For cost reasons, logical memory and address spaces are not implemented directly but simulated. The contents of the logical memory ar...
