Detailed Description

template<typename Derived>
class DNDS::DeviceTransferable< Derived >

CRTP mixin giving a class uniform to_device / to_host / device / getDeviceArrayBytes methods.

The derived class only has to expose its device-managed members via a for_each_device_member(F&&) method template that invokes F(m) once per MemberRef<ArrayPairType>:

template <typename F>
void for_each_device_member(F&& f)
{
    for_each_member_list(device_array_list(), std::forward<F>(f));
}

Once that is in place, all four member functions below iterate every registered pair and forward the device operation.

Member Function Documentation

device()

template<typename Derived >

DeviceBackend DNDS::DeviceTransferable< Derived >::device ( )

inline

Consistent device backend across all registered pairs.

Asserts that every pair's father and son live on the same backend; throws a descriptive message if not.

Definition at line 61 of file DeviceTransferable.hpp.

Here is the call graph for this function:

getDeviceArrayBytes()

template<typename Derived >

index DNDS::DeviceTransferable< Derived >::getDeviceArrayBytes ( )

inline

Total footprint of every registered father+son pair in bytes.

Definition at line 94 of file DeviceTransferable.hpp.

to_device()

template<typename Derived >

void DNDS::DeviceTransferable< Derived >::to_device ( DeviceBackend  B )

inline

Mirror every registered ArrayPair to the given device backend.

Definition at line 39 of file DeviceTransferable.hpp.

Here is the caller graph for this function:

to_host()

template<typename Derived >

void DNDS::DeviceTransferable< Derived >::to_host ( )

inline

Pull every registered pair back to host memory.
