[Qlustar-General] node-configuration
by Tobias Moehle 02 May '19

Dear all, I'd like to report some trouble I had with the node configuration (qlustar v. 10.1.1-2): I tried to add some nfs-mount as described here: https://docs.qlustar.com/en-US/Qlustar_Cluster_OS/10.1/html-single/Administ… However, the script was not executed. It took me quite a while to figure out that these scripts are run with 'run-parts' (see /lib/qlustar/nfs-rc for those who are interested) and this does not accepct stripts with '.sh' (see e.g. the first answer here: https://superuser.com/questions/719424/how-do-you-use-the-run-parts-command for some explanation). Probably it would be great to either use the '--regex'-option to circumvent this behaviour or at least to tell users about it? Moreover, I wondered if there is way to adjust the scripts in '/lib/qlustar/'? Unfortunately, I didn't find their place on the headnode. Best regards, Tobias Moehle

[Qlustar-General] Renaming slurm gres gpu type
by Bryan Hill 24 Apr '19

24 Apr '19

Hi All: Is there a preferred way to change the name of a GPU gres type in Qluman? For example, we have to use --gres=gpu:geforce-rtx-2080-ti:2 to request that specific model of GPU. I would like to simplify that to something like: --gres=gpu:2080ti:2 When I attempt to change the names from what the GPU Wizard had originally set up, it makes things go badly, in that the the gres resource is no longer recognized. Is there a clean way to do this? Thanks, Bryan

[Qlustar-General] QluMan containerization
by Hernán Morales Durand 01 Apr '19

Hello, I have a node where I've installed QluMan 10.1.1 so I can configure the Cluster using the GUI. Now this node is NOT added to the cluster (i.e. not currently booting any OS image) so it's somewhat "wasted". As far as I understood the OS images are executed in the nodes in RAM memory. So theoretically I could boot this node with an OS image and later mount the fs to try qluman-10.1.1.19-singularity.sqsh however I don't see how that could work because of lib compatibility. Is that correct/feasible? And I wonder if there is a container image already built specifically to run the qluman.sqsh application. I couldn't find none so far and I wanted to ask before starting to explore this path. What do you recommend? Cheers, Hernán
