[slurm-users] GPU exclusively for one account

2021-02-25 Thread Baldauf, Sebastian Martin
Hello, I just want to ask if someone has an idea how to give a GPU and some CPUs of a node to one account exclusively but keep the remaining CPUs of this node available for all users. For me it looks like that using partitions is only working for whole nodes, while with reservation it is not possi
