Синхронизация выполняется параллельно вгруппах на каждом уровне иерархии, что позволяет локализовать межпроцессные взаимо-действия. Реализация выполнена на базе библиотеки Open MPI. Эксперименты на серверес двумя процессорами Huawei Kunpeng (128 ядер, 4 NUMA-узла) показали, что предложен-ный алгоритм с группировкой процессов по NUMA-узлам обеспечивает минимальноевремя выполнения по сравнению с известными методами и устойчив к изменению способараспределения процессов по процессорным ядрам.</p></abstract><trans-abstract xml:lang="en"><p>A hierarchical MPI barrier synchronization algorithm creating groups of processes that share common re-sources at the memory hierarchy levels (L2/L3 caches, NUMA node, socket) is proposed. Synchronization isperformed in groups at each level of the hierarchy. Experiments on a dual-socket server with two HuaweiKunpeng processors (128 cores, 4 NUMA nodes) showed that the proposed algorithm with NUMA nodesprocess grouping provides the minimum execution time compared to known methods and is resistant to differ-ent schemes of process placement.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>барьер</kwd><kwd>синхронизация</kwd><kwd>MPI</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arrier</kwd><kwd>shared memory</kwd><kwd>MPI</kwd><kwd>NUMA</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Государственного задания No 071-03-2022-001.</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">Jain S., Kaleem R., Balmana M., Langer A., Durnov D., Sannikov A. and Garzaran M.
