CUDA sparse-matrix class about kaldi HOT 7 CLOSED

@naxingyu, do you have time for this? I know you've done a lot lately..

from kaldi.

I'll do this next week (this week on phone-topology).

from kaldi.

OK thanks-- check in with us when you've done the phone-topology thing
though, because @hainan-xv was considering doing it.

I'll create a interface for CuRowSparseMatrix similar to CuSparseMatrix.
Some basics are

• return numbers
• copy and swap functions
• data accessors and randomizer
• operators
• read and write
• a constructor from a SparseMatrix

Besides those, should I implement these?

• sum
• frobenius norm

And according to your design, I will add AddMatSmat as a member function
of CuMatrixBase, is that right?

only if you have time-- they might be useful for some diagnostics. but we
can always copy to CPU for this.

yes.

It seems I should create a RowSparseMatrix class too? To handle the
non-cuda situation?

X.

Actually no, because the regular SparseMatrix class already stores its data
by row.
