mtcp_core_affinitize - bind a calling thread to a specific CPU core #include <mtcp_api.h> "int mtcp_core_affinitize(int " cpu ); mtcp_core_affinitize () binds a calling thread to a specifc CPU core. This function is a utility function which internally performs sched_setaffinity () for dedicating one CPU to a particular thread, and numa_set_membind () for restricting any future memory allocation to happen within the NUMA node. This function is used by end TCP applications to pin their application threads to a specific core in order to gain performance benefits. For example, restricting an application thread to run on a single CPU core avoids any cache invalidation that can be caused when the thread is moved from one CPU core to another CPU core. The function requires a sole "cpu" integer argument that passes the CPU core-id of the system on which the stack is instantiated. """""""""""""""""""""""""""""""""""""""""""""""""""""""""""

Passing an invalid CPU core-id (value < 0 or value > max_cpus) will prevent the creation of the mTCP stack. """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
