Hi Chris, I have no experience with gres nic config, but can't you use /sys/class/net instead of /dev? I think there is also a link to the pci device..

Hi folks, Just curious if anyone out there is currently using the "nic" gres type and how do you deal with the fact that the Files= entry in gres.conf has to refer to an existing device when network devices generally don't appear under /dev? Do you just hack with with "touch" or "mkdev" ? The bug that introduced the code was: https://bugs.schedmd.com/show_bug.cgi?id=1718#c3 and the example given was: Name=nic File=/dev/mlx4_0 CPUs=0-1 Name=nic File=/dev/mlx4_1 CPUs=2-3 but nothing like those names will exist with Mellanox OFED.
