Arguments

newteam A valid SHMEM team handle.

Description

The shmemx_team_n_pes function returns the number of processes in the
team. This will always be a value between 1 and the total number of
PEs. For the team SHMEM_TEAM_WORLD, this will return shmem_n_pes.
Every team must have a least one member. All processes in the team
will get back the same value for the team size.

Error checking will be done to ensure a valid team handle is provided.
All errors are considered fatal and will result in the job aborting
with an informative error message.

Notes

By default, SHMEM creates two predefined teams that will be available
for use once the routine start_pes has been called. These teams can be
referenced in the application by the constants SHMEM_TEAM_WORLD and
SHMEM_TEAM_NODE. Every PE process is a member of the SHMEM_TEAM_WORLD
team, and its rank in SHMEM_TEAM_WORLD corresponds to the value of its
global PE rank. The SHMEM_TEAM_NODE team only contains the set of PEs
that reside on the same node as the current PE.
