Abstract

The article analyses the behavior of two kinds of multiprocessor multidisk storage server architectures for a data intensive application, namely for spatial queries in geographical information systems (GIS). The two kinds of servers are: (1) a workstation cluster architecture with multiple processors, multiple disks, and a shared bus shared memory architecture; (2) a distributed memory architecture, similar to the T9000 transputer based architectures, where processing nodes and disk nodes are connected by a high throughput crossbar switch. The GIS application under investigation is the map overlay with map at different scales and resolutions

Distributed shared memory

In computer science, distributed shared memory (DSM) is a form of memory architecture where physically separated memories can be addressed as a single shared address space. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two processors refers to the same location in memory. Distributed global address space (DGAS), is a similar term for a wide class of software and hardware implementations, in which each node of a cluster has access to shared memory in addition to each node's private (i.

Geographic information system

A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.

Multi-core processor

A multi-core processor is a microprocessor on a single integrated circuit with two or more separate processing units, called cores, each of which reads and executes program instructions. The instructions are ordinary CPU instructions (such as add, move data, and branch) but the single processor can run instructions on separate cores at the same time, increasing overall speed for programs that support multithreading or other parallel computing techniques.
