Detailed Description

template<typename TVector>
class ug::ParallelVector< TVector >

Parallelization Wrapper to make a Vector usable in parallel A ParallelVector is a wrapper around a sequential vector to make it usable in parallel. It has all the function a sequential vector supports, since it is derived from it. Furthermore the ParallelStorageType is remembered and can be switched. In addition some functions of the sequential vector are overwritten to adapted the functionality to parallel (e.g. norm, set).

Member Function Documentation

◆ add_storage_type()

template<typename TVector >
void ug::ParallelVector< TVector >::add_storage_type ( uint  type)
inline

adds a storage type

type may be any or-combination of constants enumerated in ug::ParallelStorageType.

References ug::ParallelVector< TVector >::m_type.

◆ change_storage_type()

template<typename TVector >
bool ug::ParallelVector< TVector >::change_storage_type ( ParallelStorageType  type)

changes to the requested storage type if possible

◆ check_storage_type()

◆ clone()

template<typename TVector >
SmartPtr< ParallelVector< TVector > > ug::ParallelVector< TVector >::clone

clones the vector (deep-copy) including values

◆ clone_without_values()

template<typename TVector >
SmartPtr< ParallelVector< TVector > > ug::ParallelVector< TVector >::clone_without_values

clones the vector (deep-copy) excluding values

◆ dotprod()

template<typename TVector >
number ug::ParallelVector< TVector >::dotprod ( const this_type v)
inline

dotprod (overwrites TVector::dotprod())

Returns the dot product of the vector. First, the dot prod of each process is computed using the dotprod() method of the sequential vector. Then, the results are summarized over all processes.
