Detailed Description

This represents 'thread_limit' clause in the '#pragma omp ...' directive.

#pragma omp teams thread_limit(n)

In this example directive '#pragma omp teams' has clause 'thread_limit' with single expression 'n'.

#pragma omp teams thread_limit(dims(2): x, y)

In this example directive '#pragma omp teams' has clause 'thread_limit' with the 'dims' modifier specifying two dimensions. The list specifies the limit on the number of threads in each dimension.

When 'ompx_bare' clause exists on a 'target' directive, 'thread_limit' clause can accept up to three expressions.

#pragma omp target teams ompx_bare thread_limit(x, y, z)
