CONTROL SYSTEM FOR HIGH-LEVEL PARALLEL COMPUTER SYSTEM USING SOFTWARE ARCHITECTURE

摘要

PURPOSE: To provide the control system which uses the software architecture, equipped with several layers of abstract bodies, controlling the high-level parallel computer system. ;CONSTITUTION: An abstract physical machine 10 (1st layer) includes a group of abstract physical processors and is considered as a microkernel. A 2nd layer includes a virtual machine 2 and virtual processors 16. The virtual machine is equipped with a virtual address space and a group of virtual processors connected by virtual topology. The virtual machine is mapped to the abstract physical machines and each virtual processor is mapped to the abstract physical processors. A 3rd layer defines threads 18. The threads are processes with light weight which run on the virtual processors. The abstract physical machine, abstract physical processors, virtual machines, virtual processors, thread groups, and threads are preferably all objects of a first class.;COPYRIGHT: (C)1995,JPO
