Use OMP_THREAD_LIMIT to set the
thread-limit-var internal
control variable.
thread-limit-var is used to indicate the
number of OpenMP threads to be used for the whole program. The function
omp_get_thread_limit can
be used to retrieve this value at run time. The value for OMP_THREAD_LIMIT
is a positive integer. If a value is chosen that is more than the
number of threads that can be supported or is not a positive integer,
the runtime sets a default value for
thread-limit-var of OMP_NUM_THREADS
or the number of available processors, whichever is greater.
Note: if thread-limit-var is
set, the default value of the nthreads-var internal control
variable is equal to thread-limit-var or the number of available
processors, whichever is less.
