CUDPP 1.0 Alpha Release Adds Segmented Scan, Sparse Matrices
[b]CUDPP 1.0 alpha[/b]

[url="http://www.gpgpu.org/developer/cudpp"]CUDPP 1.0[/url] is here! We've revamped the CUDPP public interface to improve usability, and we've added a bunch
of new features, with even more to come. Because this interface is quite new, we want to give people a chance
to try it out and send us feedback on any issues they discover. For this reason we've called this an alpha
release -- we may yet tweak the interface. In addition, there are a couple of features that didn't make this
release that we hope to add before 1.0 final is released. If you have feedback on the new interface, please
tell us on the [url="http://groups.google.com/group/cudpp"]CUDPP Google Group[/url]

release -- we may yet tweak the interface. In addition, there are a couple of features that didn't make this

release that we hope to add before 1.0 final is released. If you have feedback on the new interface, please
