Ok... I've cleaned up, ran a depmod on the previous/original kernel, and reinstalled kmod-nvidia. Both the depmod and the install didn't find a modules.order and another one, but seemed to install fine. Now, I see that kmod-nvidia includes the nvidia-uvm-kmod, as well as cuda libraries. How do I test to see if it can see the Tesla cards? It used to be that I'd install cuda, build the samples, and run enum_gpu. When I rebuilt the other server, with a pair of M2090s, I could build the proprietary install, and install cuda, and then build the samples, and run bin/deviceQueryDrv. Is there something I can run that I can see that it sees the cards? I haven't found anything yet. mark _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
