dot_real_op computes the dot product of the given complex arrays(treated as float arrays). And there's may have MPI communications while enabling planewave parallization strategy.

Input Parameters

Parameters

dev	: the type of computing device
A	: input array arr
dim	: size of A
lda	: leading dimention of A
batch	: batch size, the size of the result array res

Returns

res : the result vector T : dot product result
