How to setup Visual Studio 2010 for recursion

I have a GeForce 580 (2.0)

Build customization 4.0

Platform Toolset v100

In “Cuda C/C++” → “Device” → “Code Generation” compute_20,sm_21

Everything set on 64bit

So everything should be recursion-ready

But when I compile I get:

Unsupported gpu architecture ‘compute20’

Where am I wrong?

(I changed computer and vga to get recursion and dynamic allocation…)

Ps: I am on Win7 x64, I posted here since there is no Win7 section on the forum…

should it be compute_20? Or maybe you should remove the compute_20,sm_21 and just leave sm_20 there.
