Hi,
I just moved from CUDA 10.1 and using cusparseZ(D)csrmm2 (deprecated) to CUDA 11.0 using cusparseSpMM now. I also see a significant performance decrease. A similar issue has also been reported in (Performance Downgrade when changing [deprecated] cusparse<t>csrmm() to cusparseSpMM()).
Is there any progress here?
Many thanks,
Regards,
