Bayesian phylogenetic inference in the LIBI grid platform: A tool to explore large data sets

This works presents the porting on the Grid of a parallel application of phylogenetic inference, MrBayes, in the LIBI (International Laboratory of Bioinformatics) platform. Moreover a bioinformatic case study about the analysis of 11 phylogenies, including a series of large sequences data sets that represent the nascent barcode reference database for Lepidoptera is also presented. The case study has been tested on the platform and the speedup and efficiency on Itanium HP XC6000 (Intel Itanium 2 processors and Quadrics interconnects) of the SPACI consortium, University of Salento, are described. © 2008 IEEE.
