Algorithms are proposed to improve the efficiency of parallel programs execution on high-performance computer systems, in particular, when solving problems of modeling physical processes. The developed algorithms are focused on optimizing the performance of collective operations on multiprocessor SMP/NUMA nodes in the MPI standard. Read-write blocking algorithms increase the efficiency of synchronization of access to shared memory relative to the algorithms used in the Open PMIx library.
