Apply a reduction/transformation operator over a set of vectors: op(op(v[0]...v[nv1],z[0]...z[nz1]),(*reduct_obj)) > z[0]...z[nz1],(*reduct_obj) .
 Parameters:

 op  [in] Reduction/transformation operator to apply over each subvector and assemble the intermediate targets into reduct_obj (if reduct_obj != RTOp_REDUCT_OBJ_NULL ). 
 num_vecs  [in] Number of nonmutable vectors in vecs[] . If vecs==NULL then this argument is ignored but should be set to zero. 
 vecs  [in] Array (length num_vecs ) of a set of pointers to nonmutable vectors to include in the operation. The order of these vectors is significant to op . 
 num_targ_vecs  [in] Number of mutable vectors in targ_vecs[] . If targ_vecs==NULL then this argument is ignored but should be set to zero. 
 targ_vecs  [in] Array (length num_targ_vecs ) of a set of pointers to mutable vectors to include in the operation. The order of these vectors is significant to op . If targ_vecs==NULL then op is called with no mutable vectors. 
 reduct_obj  [in/out] Target object of the reduction operation. This object must have been created by the op.reduct_obj_create_raw(&reduct_obj) function first. The reduction operation will be added to (*reduct_obj) if (*reduct_obj) has already been through a reduction. By allowing the info in (*reduct_obj) to be added to the reduction over all of these vectors, the reduction operation can be accumulated over a set of abstract vectors which can be useful for implementing composite vectors for instance. If op.get_reduct_type_num_entries(...) returns num_values == 0 , num_indexes == 0 and num_chars == 0 then reduct_obj should be set to RTOp_REDUCT_OBJ_NULL and no reduction will be performed. 
 first_ele_offset  [in] (default = 0) The index of the first element in this to be included. 
 sub_dim  [in] (default = 1) The number of elements in these vectors to include in the reduction/transformation operation. The value of sub_dim < 0 means to include all available elements. The value of sub_dim == 0 means to include none of the elements of the vector. This last value is somewhat undefined but has meaning in some specialized contexts (such as for SPMD vectors). 
 global_offset  [in] (default = 0) The offset applied to the included vector elements. 
Preconditions:

[
num_vecs > 0 ] vecs[k]>space()>isCompatible(*this>space()) == true , for k = 0...num_vecs1 (throw Exceptions::IncompatibleVectorSpaces )

[
num_targ_vecs > 0 ] targ_vecs[k]>space()>isCompatible(*this>space()) == true , for k = 0...num_targ_vecs1 (throw Exceptions::IncompatibleVectorSpaces )

[
num_targ_vecs > 0 ] The vectors pointed to by targ_vecs[k] , for k = 0...num_targ_vecs1 must not alias each other or any of the vectors vecs[k] , for k = 0...num_vecs1 . You have be warned!!!!

0 <= first_ele_offset < this>space()>dim() (throw std::out_of_range )

global_offset >= 0 (throw std::invalid_argument )

sub_dim  first_ele_offset <= this>space()>dim() (throw std::length_error ).
Postconditions:

The vectors in
targ_vecs[] may be modified as determined by the definition of op .

[
reduct_obj!=RTOp_REDUCT_OBJ_NULL ] The reduction object reduct_obj contains the combined reduction from the input state of reduct_obj and the reductions that where accumulated during this this function invocation.
The logical vector passed to the op.apply_op(...) function is:
v(k + global_offset) = this>get_ele(first_ele_offset + k)
, for k = 0 ... sub_dim1
where v represents any one of the input or input/output vectors. The situation where first_ele_offset == 0 and global_offset > 1 corresponds to the case where the vectors represent constituent vectors in a larger aggregate vector. The situation where first_ele_offset > 0 and global_offset == 0 is for when a subview of the vectors are being treated as full vectors. Other combinations of these arguments are also possible.
