INFLUENCE OF CALCULATION ACCURACY ON THE TIME AND RESULTS
OF SOLVING THE INVERSE PROBLEM OF MAGNETOSTATIC NONDESTRUCTIVE TESTING. NEED OF PARALLEL COMPUTATIONS
DOI: 10.17804/2410-9908.2015.5.022-030 Examples of computer modeling of the inverse problem are given. It is shown that the solution of such problem for defects of arbitrary form demands computing resources which can be provided only high-performance multiprocessor systems.
