An increasing number of applications in physical and social sciences require the analysis of large graphs. The efficiency of these programs strongly depends on their memory usage especially the locality of graph data access. Intuitively, the locality in computation should reflect the locality in graph topology. Existing locality models, however, operate either at program level for regular loops and...
Considering the environmental stress characteristics of storage conditions, Fault Mode Mechanism and Effect Analysis (FMMEA) method is introduced to Dynamic Turned Gyroscopes (DTG) to determine the affecting stress type and the weak component. The analysis result shows that the temperature stress is confirmed as the most important influencing environmental factor, related to the performance degradation...
In large-scale cluster systems, interconnecting thousands of computing nodes increase the complexity of the network topology. Nevertheless, few existing computational models consider the impact of hierarchical communication latencies and bandwidths caused by the network complexity. In this paper we propose a new parallel computational model called LogGPH with a new parameter H incorporated into the...
