Is this a new feature, an improvement, or a change to existing functionality?

Improvement

How would you describe the priority of this feature request

High

Please provide a clear description of problem this feature solves

i want cuGraph to optimize the SCC algorithm. because i have a directed graph and i can t find any other algorithm to help me in finding vertices connections.

Describe your ideal solution

the current solution creates a dense representation of the graph (actually 2 copies, A and A transpose) and do matrix multiplications to compute the SCC. This is going to require hundreds of gigabytes of GPU memory for a graph. if there is a method that will take less space it would be great.

Describe any alternatives you have considered
