Re: [slurm-users] slurmdbd.service gives: Unable to initialize auth/munge authentication plugin

That will depend where the rest of the cluster is. If they were in the VPN such as inside a corporate network that you used the VPN to connect to, they might. But if they are elsewhere in your home network, they will not. I think some VPN clients can be configured to be quite open but usually

Re: [slurm-users] Question about memory allocation

Sorry Mahmood, 10 GB per node is requested not 200 GB per node. For all nodes this counts in total to 40 GB as you request 4 nodes. The number of tasks per node does not matter for this limit. Best ;-) Sebastian Sebastian Kraus Team IT am Institut für Chemie Gebäude C, Straße des 17. Juni

A follow up to the previous email. Current state of memory of nodes are RealMemory=64259 AllocMem=1024 FreeMem=38620 Sockets=32 Boards=1 RealMemory=120705 AllocMem=1024 FreeMem=309 Sockets=32 Boards=1 RealMemory=64259 AllocMem=1024 FreeMem=59334 Sockets=32 Boards=1 RealMemory=64259

Re: [slurm-users] srun: job steps and generic resources

Dear Brian, thanks for the detailed explanation. Shame on me, that I did not pass by the relevant description of the SallocDefaultCommand as filed at the mid of the slurm.conf man page. @slurm developers: Maybe, it would be a good idea to link this paragraph directly into the salloc man page

[slurm-users] slurmdbd.service gives: Unable to initialize auth/munge authentication plugin
