Accelerating this process using Graphic Processing Units (GPUs) is thus greatly advantageous for most due to increasing data. Many algorithms give fast methods to search multiple occurrences of a given string of characters."This research report details the performance analysis of two powerful multi -pattern matching algorithms, namely Aho -Corasick and Commentz-Walter on GPU with CUDA C. Moreover, this report details which algorithm is more suitable and has better performance on GPU CUDA platform.en-USAho-CorasickCommentz-WalterGPUGraphic processing unitsString matching algorithmsThesis
