In many of Europe’s rural regions, sociodemographic changes, the transformation labour market, and advent digitalisation pose significant challenges in safeguarding services general interest (SGI). This paper draws on a broad literature review to identify key potential adaptation strategies three SGIs four European countries. Our analysis explores potentials for redesigning accessibility these ...

MPI (Message Passing Interface) is a proposed message passing standard for development of efficient and portable parallel programs. An implementation of MPI is presented and evaluated for the Meiko CS/2, a 64 node parallel computer, and a network of 8 SGI workstations connected by an ATM switch and Ethernet.

This report compares the performance of di erent computer systems for basic message passing. Latency and bandwidth are measured on Convex, Cray, Fujitsu, IBM, Intel, KSR, Meiko, nCUBE, NEC, SGI, and TMC multiprocessors. Communication performance is contrasted with the computational power of each system. The comparison includes both shared and distributed memory computers as well as networked wo...

We present an HPF implementation of BT, SP, LU, FT, CG and MG of the NPB2.3-serial benchmark set. The implementation is based on HPF performance model of the benchmark specific primitive operations with distributed arrays. We present profiling and performance data on SGI Origin 2000 and compare the results with NPB2.3. We discuss advantages and limitations of HPF and pghpf com-

Abstract. The Oxford Supercomputing Centre OSC1 was established in April 1998 to provide high-performance computing services to a consortium of Oxford University research groups. The main computer resource, an 84-processor SGI Cray Origin 2000 known as Oscar, is being deployed in a wide variety of research studies covering biological, medical, chemical, mathematical, physical and engineering to...

Gamification is defined as the use of game design elements in non-gaming contexts. It is been getting a lot of attention in recent years. However, the amount of research undertaken on gamification is limited. One of the problems it faces is sustainability. Designers might overlook the elements that increase sustainability due to lack of a standard framework that contains the essential component...

The shared-memory multiprocessor system recently has attracted a lot of attention because of its low cost and wide availability to the graphics researchers. In this paper, we show practical parallel solutions to the following volume graphics[4] problems: volume texture modeling, volume texture rendering, and voxelization for unstructured grid rendering. All these solutions process 2D and 3D arr...

The Nonconforming Spectral Element Method (NSEM) solves PDEs in complex geometries with high accuracy, however, it is an expensive method. Since parallel computation is eeective in decreasing CPU time, a parallel algorithm for the NSEM is presented. Implementations on SGI Power Challenge using MPI are evaluated in terms of measured speedup and parallel eeciency for schemes of one element and mu...

Methods using OpenMP directives have been studied to parallelize an inherently sequential GaussSeidel algorithm on shared memory computers. Both hyperplane and pipeline parallelization schemes have been implemented to a non-equilibrium real-gas flow simulation code. The effects of different parallelization strategies and grid sizes on the parallel efficiency have been investigated on SGI Origin...
