Detailed Description

template<class TK, class T>
class SUNphi::TensStor< TK, T >

Tensor Storage holding the resources for a tensor

The tensor storage allocates and deallocates the memory location where a tensor is materially stored, keeping track of the amount of memory allocated. Facilities to reallocate the memory are provided.

Todo:

many things, including considering a static storage if size is small and statically known

Definition at line 29 of file TensStor.hpp.

Constructor & Destructor Documentation

template<class TK, class T>

SUNphi::TensStor< TK, T >::TensStor ( const TensStor< TK, T > &  oth )

inlineexplicit

Copy constructor (test)

Todo:

improve memcpy, this could be parallelized in many ways, we have to implement memory manager soon

Definition at line 205 of file TensStor.hpp.
