efficiency of Component Propagate functions #2

Closed hainan-xv closed 7 years ago

hainan-xv commented 7 years ago

In file src/rnnlm/rnnlm-component.cc, functions

void LmLinearComponent::Propagate(const SparseMatrix<BaseFloat> &sp, CuMatrixBase<BaseFloat> *out) const

void LmLinearComponent::UpdateSimple(const SparseMatrix<BaseFloat> &in_value, const CuMatrixBase<BaseFloat> &out_deriv)

have very inefficient implementations. @freewym Can you implement them at the CuMatrix level and write cuda kernel function for them? Thanks.

freewym commented 7 years ago

which branch?

hainan-xv commented 7 years ago

shortcut

freewym commented 7 years ago

It cannot compile.

hainan-xv commented 7 years ago

fixed. Try pull'ing the new version?

freewym commented 7 years ago

still failed....

hainan-xv commented 7 years ago

did you make clean and re-./configure ? it might have to do with the CUDA update I feel

freewym commented 7 years ago

yes.
