Nvidia CUDA on MRG Realtime 2.1

Not sure if this is the place to post this question but I have been searching to see if Nvidia CUDA is supported on MRG Realtime 2.1  I found a post online in 2008 that said there was no planned support for CUDA in MRG realtime.  I have not been able to find and conclusive information on the RHN site.   I was hoping someone could point me in the correct directions

Thanks
