<html><body><div><div>Hi Everyone,<br></div><div><br></div><div>thanks for the many replies and hints. I think I will go for an NVIDIA T4 for now and try to get it working in our OpenStack cluster by following your guidelines @Gene. I will report back on the progress.<br></div><div><br></div><div>Cheers,<br></div><div>Oliver<br></div><div><br></div><blockquote type="cite"><div>On Jan 13, 2023, at 4:20 PM, Dmitriy Rabotyagov <noonedeadpunk@gmail.com> wrote:<br></div><div><br></div><div><br></div><div><div><div>You are saying that, like Nvidia GRID drivers are open-sourced while<br></div><div>in fact they're super far from being that.
