how do i get optix on cpu running under windows?

i found some nvidia references claiming that they added cpu support for optix 3. However there is no information as to how to enable it. I tried installing the optix sdk and running the demos on a machine with no gpu but i get an unknown error.
they also claim that they used gpuoccelot. Last time that i tried to get that running under windows i failed to get i to link.
any pointers as to whether it is possible and how?

thanks

Thanks, so it’s not possible at the moment. Talks mention using gpuocelot for that. Assuming that I get gpuocelot running under windows this time around, any idea if it’s possible to replace the dependency on cudart with the dependence on gpuocelot to get the optix to run using ocelot myself?
Thanks
