[Rtk-users] Fwd: Remote Control Issue

[Guangming Zang]

Thanks all for your help,Simon.
I will try it again when i am at home :)
As for using  Cuda in remote control, i can handle it:just like what Chao
said, change lab computer to TCC.

What confused me at the beginning is that a cuda error shown while i did
not call cuda at all, and thanks for fixing it.
Regards
Guangming
