cuda sparse operations in CSC format

votes

I've been looking to use cuSPARSE to multiply a sparse matrix by a dense matrix.
My sparse matrix is in CSC (Compressed Sparse Column Format).

cuSPARSE supports conversion from CSC to CSR, and the multiplication in CSR format, but i've been looking for a solution that does not involve the CSC to CSR conversion.

I would like to ask if someone knows of a library or something like it that implements this.
Thanks.

CSC is CSR transposed. So just pass CUSPARSE_OPERATION_TRANSPOSE for transA
