Abstract

Sequence alignment is the process of aligning two genomic sequences. It is the first step in various bioinformatics processes and is essential in many fields of genomics and bionformatics, such as de novo genome assembly and variant detection. One such sequence alignment algorithm is the Bi-Directional Wavefront Alignment (BiWFA) algorithm, which guarantees optimal alignment with O(ns) time and O(s) space complexity. In this paper, a novel approach is presented wherein AVX-512 Single Instruction Multiple Data (SIMD) instructions are integrated into the BiWFA algorithm. Its execution time is then measured and compared against the original BiWFA library, wherein it exhibited speedups of up to 4.67x from the original.
