I’ve been using a script to set values for all GPUs in a machine which has been successful for driver version up through 384.98.
After upgrade to v387.34, the settings only affect the first device. Other cards silently ignore the command.
Trying with the following:
sudo /usr/bin/xinit /usr/bin/nvidia-settings -c :0 -a [gpu:1]/GPUMemoryTransferRateOffset[3]=500
gpu:0 works, all others ignore the command. This is true of any attribute setting sent to cards other than GPU0.
removed: not relevant
After reverting the F27 system back to Nvidia driver version 384.98, I see the problem persists. This appears to be some difference between the F27 system and the Centos7 systems. Same hardware works fine on the Centos7 system
More detail to demonstrate what I am seeing and to reflect Title change:
On Centos7:

Same hardware running different OS. Behavior is the same whether I am running on driver version 384.98 or 387.x
