Title: GPU mining on machines that are not logged in Post by: sokay on July 14, 2011, 02:12:04 PM Hello,
I have been searching these boards for some time, as well as the rest of the interwebs. And I would like to know if there is a way to GPU mine on a PC before a user is logged in. From what I can tell, graphical drivers are not accessible by programs until a user is logged in. I have a group of computers that sit idle and can remotely run programs on said machines but I am not able to log these machines into any account or boot to another OS. They are running Win 7 x64. I have tried several different miners. But the only one i have been able to get working is ufasoft's CPU miner. I get OpenCL errors for most of the other miners.

Have you tried GUI Miner using command lines in a batch file? This may work, I have not tried it though for a machine that isn't logged in, but you should be able to have this in as a startup entry when the OS loads?

I have not tried adding the batch file as a start up item as it would be harder for me to interact with the running miner. But I guess that is my next step.
The latest miner I tried was cgminer, and when it is launched I get the error "Redirection is not supported". As my account is still a newbie i have been unable to post in the proper thread when looking for support. As this is the first miner to give me an error other than OpenCL. When I log onto one of these machines I am able to launch any mining client and start mining with out any hiccups.

(without having to be logged in)

The same errors - that alude to no GPU detected were found in the log. From looking around, it seems that graphics drivers and computer are not made available by the system until a user is actually logged into the machine. I am guessing it is either a win 7 security 'feature' or some sort of power saving function to limit the active processes running before a user is actually trying to do work. |
