Sparse data on GPU

Accelerated Computing CUDA CUDA Programming and Performance

Does GPU handles sparse data well? Is there going to be performance loss?
Are there any special data structures for handling sparse data in CUDA?

Thanks.

Can you be more specific? What kind of sparse data are you looking to store? Sparse matrix data, or something else? There is a thread in the General Computing forum about Sparse Matrix multiplication, and it includes the author’s code.
