Errors raised for large datasets like Reddit #6

Thanks for your good work. But I find your code does not work for large datasets like Reddit with around 233k nodes and 115m edges. It raises the error 'CUDA error: an illegal memory access was encountered'.

I perform further experiments. I find the code works fine if I keep only 30m edges. But the same error is raised when I keep 40m edges.

I also test it on other large datasets like LiveJournal-d and com-orkut. They have similar performance.

Best wishes

Update: we find this error only happens when enable_rabbit==True
