Abstract : This report presents the implementation of a protein sequence comparison algorithm specifically designed for speeding up time consuming part on parallel hardware such as SSE instructions, multicore architectures or graphic boards. Three programs have been developed: PLAST-P, TPLAST-N and PLAST-X. They provide equivalent results compared to the NCBI BLAST family programs BLAST-P, TBLAST-N and BLAST-X with a speed-up factor ranging from 5 to 10.

Keywords : Parallelization similarity search indexing BLAST GPU SIMD
