can i build it against cuda9 and copy the binary to rigs with only cuda8 installed? does it run slower than cuda9 rig?
All you need is recent Nvidia driver with CUDA9 support, you won't need any toolkits installed.
Great, thanks. Does the CPU of build machine matter? I have G1840, g3900 ,g4560, e3 1231, which one is better to build the binary and copy to other rig with different CPU?
I use ubuntu 16, nvOC.
