PROSITE provides rich documentation entries describing protein domains, families and functional sites, associated patterns as well as generalized profiles to identify them. Generalized profiles in PROSITE are often used to detect distantly related proteins by doing sequence comparison. The developments of the PROSITE have increased the discriminatory power of generalized profiles. However in practice,...
In this paper we present XSW, a new parallel Smith-Waterman algorithm for searching protein sequence databases on the Xeon Phi coprocessor. In order to make full use of the compute power of the many-core Xeon Phi hardware, we have used a two-level parallelization scheme: the thread level coarse-grained and VPU level fine-grained parallelism to implement our algorithm. At the thread level, XSW employs...
Scanning protein sequence database is an often repeated task in computational biology and bioinformatics. However, scanning large protein databases, such as GenBank, with popular tools such as BLASTP requires long runtimes on sequential architectures. Due to the continuing rapid growth of sequence databases, there is a high demand to accelerate this task. In this paper, we demonstrate how GPUs, powered...
