Résumé :
Biological Sequence Comparison is a very important problem in Bioinformatics. Comparing sequences with exact methods such as Smith-Waterman takes a considerablee amount of time and, for this reason, parallel strategies have been employed to obtain results faster. In this talk, we will first present the biological sequence comparison problem and some exact algorithms used to solve it. We will then talk about three case studies: (a) exact alignment of Megabase DNA sequences in GPUs (Graphics Processing Units); (b) exact comparison of a set of protein query sequences with a huge genomic database in a hybrid platform composed of multicores and GPUs and (c) exact comparison of a set of protein sequences with a huge genomic database in a Federated Public Cloud environment.
Short Bio
Alba Cristina Magalhaes Alves de Melo received the Ph.D. degree in Computer Science from the Institut National Polytechnique de Grenoble, France, in 1996, the Ms.C. degree in Computer Science from UFRGS, Brazil, in 1991 and the BS degree in Computer Science from UnB, Brazil, in 1986. She is currently an Associate Professor at the University of Brasilia, Brazil, and a CNPq Researcher level 1D.
