Does CUDPP 1.1.1 version support sorting in 64 bit ?

Hi all,

I would like to ask about the CUDPP 1.1.1 version whether support sorting in 64 bit or long type ?

You should probably ask on the CUDPP forum, but from looking at the API I don’t think so (just 32-bit). I believe it radix sorts 4 bits at a time, so it could be extended quite easily.

I think Thrust does support comparison sorts with longer keys:
