We have over 300,000 machines, please reply as soon as possible！！！
I don't doubt the urgency of the matter. However 300,000 computers is a bit over the top number.
Are you telling me that you about 1/4th of the Ethereum network (300,000 x 5 GPUs on average x 50 Mh/s each = 75 GH/s), and don't know basic shell commands in regards to cuda deployment? Something does not fit.
As for Cuda installation, simply follow nVidia's guide and generally it works to most Debian derived distros that I have tried.
