Library Handles
===============

The NVSHMEM library provides a set of predefined named constant handles.
All named constants can be used in initialization expressions or
assignments, but not necessarily in array declarations or as labels in
*C* switch statements. This implies named constants to be link-time but
not necessarily compile-time constants.

.. c:var:: NVSHMEM_TEAM_WORLD

Handle of type *nvshmem_team_t* that corresponds to the world team that
contains all PEs in the NVSHMEM program.

.. c:var:: NVSHMEMX_TEAM_NODE

Handle of type *nvshmem_team_t* that corresponds to the team that
contains all PEs in the same node as the calling PE. Using this team in
a call to *nvshmem_team_my_pe* may provide an index suitable for use
with *cudaSetDevice*.
