Member Typedef Documentation

Data

template<typename T >

using bdm::SharedData< T >::Data = std::vector<AlignedT>

Data type definition for a vector whose entries fill full cache lines. A vector whose components' sizes are a multiple of the cacheline size, e.g sizeof(Data[i]) = N*hardware_destructive_interference_size.

Definition at line 58 of file shared_data.h.
