To avoid an overflow in the index range we divide first by the number of elements per function call and then by the number of workers.

inlinestaticconstexprprivate

calls the functor and forward the data T_repeat times

The calls to the functor are independent and compile time unrolled to support instruction parallelism.

Parameters

iter	the caller must ensure tha the interator can be increased T_repeat times without jumping over iter.end()
