◆ get_available_nodes()

std::vector<NodeData> anonymous_namespace{numa.cpp}::get_available_nodes ( )

Returns the list of available NUMA nodes.

If no NUMA information is available, we put all cores into a NUMA 0 node. If CPUs are available for which the corresponding memory node is not available (this happens on my desktop), we assign these CPUs to NUMA node 0.
