Re: [Condor-users] Condor with CUDA on windows

[Ziliang Guo <ziliang@xxxxxxxxxxx>]

Another user sent a similar question and I responded here:
https://lists.cs.wisc.edu/archive/condor-users/2012-January/msg00038.shtml

Simplistically, due to the changed security model in Vista and higher,
access to the video card is severely restricted in the session 0 that
Condor and jobs run in.  Currently the only way to run a CUDA or any
job that requires a GPU on Windows using Condor is to run Condor as a
personal Condor.  This however requires that a user be logged into the
machine to start up and keep Condor running.  You also lose the
sandboxing from the user that Condor does when running as a service.
