\section{\code{teams} Construct on Host}

\label{sec:host_teams}

Originally the \code{teams} construct was created for devices (such as GPUs)

for independent executions of a structured block by teams within a league (on SMs).

It was only available through offloading with the \code{target} construct,

and the execution of a \code{teams} region could only be directed to host

execution by various means such as \code{if} and \code{device} clauses,

and the \code{OMP\_TARGET\_OFFLOAD} environment variable.

In OpenMP 5.0 the \code{teams} construct was extended to enable the host

to execute a \code{teams} region (without an associated \code{target} construct),

with anticipation of further affinity and threading controls in future OpenMP releases.

In the example below the \code{teams} construct is used to create two

teams, one to execute single precision code, and the other

to execute double precision code. Two teams are required, and

the thread limit for each team is set to 1/2 of the number of

available processors.
