Заголовок статьи: Shared memory access optimization for PMIx standard implementation


The results in the field of optimization of system software stacks for distributed computing systems based on the process management Interface (PMI) are obtained. Algorithms for synchronizing access to shared memory with a predominance of reading operations, which are typical for PMIx implementations, are considered. The locking schemes N(mutex+signal) and N-MCS are proposed. Experimental estimates have shown a reduction in the overhead of both read and write operations.
