Предложена параллельная вычислительная схема, позволяющая моделировать образцы большого размера путем разбиения их на ячейки и проведения моделирования на нескольких ячейках одновременно. Выполнена валидация получаемых на параллельной схеме результатов путем сравнения с результатами для классической линейной схемы. В рамках разработанной параллельной модели рассчитаны релаксационные кривые образцов сверхпроводника с различными концентрациями пиннинга. Оценена скорость релаксации магнитного потока.</p></abstract><trans-abstract xml:lang="en"><p>The Monte Carlo method is used to calculate the magnetization of the superconducting bismuth cuprate with different pinning concentrations. A parallel calculation scheme is proposed that allows modeling of large-size samples by dividing them into cells and performing modeling on several cells simultaneously. The results obtained in the parallel scheme are validated by comparing them with the results for the classical linear scheme. Relaxation curves of superconductor samples with different pinning concentrations are calculated within the framework of the developed parallel model. The relaxation rate of the magnetic flux is estimated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокотемпературный сверхпроводник</kwd><kwd>намагниченность</kwd><kwd>пиннинг</kwd><kwd>вихри Абрикосова</kwd><kwd>параллельные расчеты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-temperature superconductor</kwd><kwd>magnetization</kwd><kwd>pinning</kwd><kwd>Abrikosov vortices</kwd><kwd>parallel computations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования РФ (проект государственного задания FSWU-2023-0031).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Desikan A., de Bruyn B.J.H., Krop D.C.J., Lomonova E.A. // IEEE Trans.
