Put this well out of the way of anything important.

max_threads_on_node

numa_index

constexpr auto isimud::exchanges::common::thread_traits::numa_index =static_cast<unsigned short>(jmmcg::ppd::numa_cpu_traits::is_numa)

inlinestaticconstexpr

The numa-node upon which the code is compiled to run optimally.

This value should be the same as that used by numactl in the start-script (e.g. "start_all_links.sh"), otherwise the code will run on the wrong processor. (One can determine which node the code has been compiled for by running the executable with the "--help" option.)
