TMVA::DNN::TCpuBuffer< AFloat > Class Template Reference

template<typename AFloat>
class TMVA::DNN::TCpuBuffer< AFloat >

TCpuBuffer.

Since the memory on the CPU is homogeneous, only one buffer class is required. The host and device buffer classes are the same and copying between the host and device buffer is achieved by simply swapping the memory pointers.

Memory is handled as a shared pointer to a pointer of type AFloat, which is the floating point type used for the implementation.

Copying and assignment of TCpuBuffer objects performs only a shallow copy meaning the underlying data is shared between those objects.

Template Parameters

AFloat

The floating point type used for the computations.
