To solve real-world discrete optimization problems approximately metaheuristics such as simulated annealing and other local search methods are commonly used. For large instances o...
Clusters of PC containing mostly general purpose hardware have become more and more usable for high performance computing tasks in the past few years. Clustering existing systems ...
This paper presents a modeling method particularly suited to analyze interactions between Message Passing Interface MPI library execution and distributed cache coherence protocol....
