Abstract

Algorithm MinNumaDist for barrier’s root selection is proposed. A root process allocates memory pages for shared counters and flags from its NUMA node. Total distance is minimized to all NUMA nodes (closeness centrality) by the algorithm. MinNumaDist reduces barrier’s time by 1035% for asymmetrical NUMA subsystems - for different number of processes on NUMA nodes or different number of NUMA nodes used from each socket.
