示例1: parallel_for_workitem

ParallelForFunctor f) {
#if defined(_OPENMP) && (!defined(TRISYCL_NO_BARRIER) && !defined(_MSC_VER))
/* To implement barriers With OpenMP, one thread is created for each
work-item in the group and thus an OpenMP barrier has the same effect
of an OpenCL barrier executed by the work-items in a workgroup
The issue is that the parallel_for_workitem() execution is slow even
when nd_item::barrier() is not used
