چکیده
User interfaces represent a fundamental component of geographic information systems (GIS) and geographic database management systems (DBMS). We propose in this paper a simple architecture for designing Geographic Database User Interfaces (GDUI). The model and architecture presented below are the result of a GDUI kernel implementationnRig93] with the database GeO2 DRS93b]. Using this model we make a rst proposal for multiple scale map display.

A Map Editing Kernel Implementation: Application to Multiple Scale Display
User interfaces are a fundamental component of applications using as support Geographic Information Systems (GIS) and geographic DataBase Management Systems (DBMS). We propose in this paper a model and an architecture for designing Geographic Database User Interfaces (GDUI). A GDUI kernel based on this architecture has been implemented using, at the interface programming level, X Windows, Motif...

متن کاملDynamic load-balancing on multi-FPGA systems: a case study
In this case study, we investigate the impact of workload balance on the performance of multi-FPGA codes. We start with an application in which two distinct kernels run in parallel on two SRC-6 MAP processors. We observe that one of the MAP processors is idle 18% of the time while the other processor is fully utilized. We investigate a task redistribution schema which serializes the execution o...
متن کاملComputational Fluid Dynamics on Hypercubes
We discuss some issues that arise in the implementation of numerical algorithms for computational fluid dynamics (CFD) on multiprocessor systems such as hypercubes. We identify several important kernel numerical algorithms from CFD that map well onto the hypercube architecture. We emphasize the importance of considering the optimal mapping for a collection of kernel algorithms used in an applic...
متن کاملEfficient Cross-domain Mechanisms for Building Kernel-less Operating Systems
We describe a set of efficient cross-domain mechanisms that allow operating systems to be implemented as cooperating applications, eliminating the need for a monolithic kernel. Our implementation, called SPACE[1, 2], can achieve higher-performance than kernel-based systems by allowing applications to build customized system services and tailor system interfaces for performance. On the SPARC arc...
