Is it possible to do a reduction on an array with openmp?

Question

Does OpenMP natively support reduction of a variable that represents an array?

This would work something like the following...

float* a = (float*) c         


        

Answer 1

OpenMP cannot perform reductions on array or structure type variables (see restrictions).

You also might want to read up on private and shared clauses. private declares a variable to be private to each thread, where as shared declares a variable to be shared among all threads. I also found the answer to this question very useful with regards to OpenMP and arrays.
