kamping::internal::OperationBuilder< Op, Commutative > Class Template Reference

Parameter wrapping an operation passed to reduce-like MPI collectives. This wraps an MPI operation without the argument of the operation specified. This enables the user to construct such wrapper using the parameter factory kamping::op without passing the type of the operation. The library developer may then construct the actual operation wrapper with a given type later. More...

Detailed Description

template<typename Op, typename Commutative>
class kamping::internal::OperationBuilder< Op, Commutative >

Parameter wrapping an operation passed to reduce-like MPI collectives. This wraps an MPI operation without the argument of the operation specified. This enables the user to construct such wrapper using the parameter factory kamping::op without passing the type of the operation. The library developer may then construct the actual operation wrapper with a given type later.

Template Parameters

Op	type of the operation (may be a function object or a lambda)
Commutative	tag specifying if the operation is commutative

Constructor & Destructor Documentation

template<typename Op , typename Commutative >

kamping::internal::OperationBuilder< Op, Commutative >::OperationBuilder ( Op && op, Commutative commutative_tag )

inline

constructs an Operation builder

Parameters

op	the operation
commutative_tag	tag indicating if the operation is commutative (see kamping::op for details)
