Datacenters are complex environments consisting of thousands of failure-prone commodity components connected by fast, high-capacity interconnects. The software running on such dat...
We perform a clustering of the Chilean Web Graph using a local fitness measure, optimized by simulated annealing, and compare the obtained cluster distribution to that of two mod...
Several researchers have illustrated that constraints can improve the results of a variety of clustering algorithms. However, there can be a large variation in this improvement, e...
Abstract. Five methods for count data clusterization based on Poisson mixture models are described. Two of them are parametric, the others are semi-parametric. The methods emlploy ...
In the Grid computing, one of the most important issues related to the Message Passing Interface (MPI) is to guarantee the expected performance in the wide area networks. To achie...
