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

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

TCudaDeviceReference.

Helper class emulating lvalue references for AFloat values that are physically on the device. Allows for example to assign to matrix elements. Note that device access through CudaDeviceReferences enforces synchronization with all streams and thus qualifies as performance killer. Only used for testing.
