text_A: X-Men (film) was written by a Canadian screenwriter.
text_B: This article discusses the analysis of parallel algorithms .. analysis. analysis of algorithms. Like in the analysis of `` ordinary '' , sequential , algorithms , one is typically interested in asymptotic bounds on the resource consumption -LRB- mainly time spent computing -RRB- , but the analysis is performed in the presence of multiple processor units that cooperate to perform computations .. analysis. analysis of algorithms. asymptotic. Asymptotic analysis. Thus , one can determine not only how many `` steps '' a computation takes , but also how much faster it becomes as the number of processors goes up .
