I forgot about RTX 2080 Ti, they work fine with Titan X:

Hello, we have both homogeneous and heterogeneous GPU servers and all of them work without problems. We have mixed GTX 1080 Ti, Titan V and Titan X, but not the more powerful cards (we have only few of them and they are working in the same machine). If the server has an adequate cooling, enough PCI-E lanes (I do not have experience with NVLink) and power supply with enough power connectors, you should not see any hardware related issues. The cards should not have a "gaming" build with large fans on the flat side of the GPU, but front-to-back airflow which will be consistent with the airflow in the server. From the software point of view, the nVidia driver should support both cards. In the Slurm configuration, I marked them as different GRES: # gres.conf Name=gpu Type=1080ti File=/dev/nvidia0 Name=gpu Type=1080ti File=/dev/nvidia1 Name=gpu Type=titanv File=/dev/nvidia2 Name=gpu Type=titanv File=/dev/nvidia3 Name=gpu Type=titanv File=/dev/nvidia4 Name=gpu Type=titanv File=/dev/nvidia5 Name=gpu Type=titanv File=/dev/nvidia6 Name=gpu Type=titanv File=/dev/nvidia7 # slurm.conf NodeName=... NodeAddr=... CPUs=40 Gres=gpu:1080ti:2,gpu:titanv:6 ... I'm not aware of any side effects of that setup. If there are any, I would also like to know about them :) Kind Regards
