Whether disordered colIndices and non-zero elements affect the speed of cuDSS or not？

Hi~
It seems that cuDSS accepts disordered colIndices and non-zero elements (of course each colIndex and non-zero element must correspond with each other) for CSR format sparse matrix. I wonder whether disordered colIndices and non-zero elements would affect the speed of cuDSS. Thanks a lot!

Hi!

Practically speaking, the sorted-ness of the input matrix has no effect on performance. There are many more parts of the algorithm in any sparse direct solver which contribute much more towards the total time ~ performance.

Thanks,
Kirill
