The paper describes Noise Measurement Suite, which is a software package for measurements of noises in a parallel computer with a large number of processors impacting the job parallelization efficiency. In literature, noise means random interferences during the process of computations, for example, owing to conflicts in a set of operating components, or asynchronous operations of the parallel computer’s control system on various processors. The suite of tools allows estimating the impact of noises on the performance of parallel user applications on the given computer and assessing a possibility of scaling the given firmware platform to create a more powerful computer system with the required performance of the given parallel applications. Keywords: multiprocessor computers, parallel application, process, operating system, Python programming language.
