Re: [slurm-users] Srun not setting DISPLAY with --x11 for one account

Thanks for the reply. I’m using 18.08. I’ve done some more digging and found that it’s not just one account but a load of newly created accounts which suffer from this problem. Older accounts are OK, but new ones don’t work. In the simplest case a completely new account fails. It contains th

Re: [slurm-users] Srun not setting DISPLAY with --x11 for one account

I’ve managed to track down the difference between the accounts which work and those which don’t – but I still don’t understand the mechanism. The accounts which work all had their home directories used on an older system. The ones which fail were only ever used on the new system. The relevant

[slurm-users] Using "curses" over an "srun" connection

I wrote a script that uses "screen" to create side-by-side windows that run co-operating processes and shows their outputs together. This looks fine when I run it remotely over an "ssh" connection. (Note that I don't need to use "ssh -X"). If I run it over an "srun" connection using forms like t

Re: [slurm-users] Srun not setting DISPLAY with --x11 for one account

The Slurm-native X11 plugin demands you use ~/.ssh/id_rsa{,.pub} keys. It's hard-coded into the plugin: /* * Ideally these would be selected at run time. Unfortunately, * only ssh-rsa and ssh-dss are supported by libssh2 at this time, * and ssh-dss is deprecated. */ static char *hostkey_pri

Ah! Thanks – that’s what I’d been missing. So the answer then is to either kludge the keys by making symlinks to the cluster and cluster.pub files warewulf makes (I tried this already and I know it works), or to update to the v19.x release and the new style x11 forwarding. Is the update to v19

Re: [slurm-users] Srun not setting DISPLAY with --x11 for one account

it's worth noting that host-based trust has a lot of nice properties for this kind of intra-cluster authentication. and in particular, you don't need fragile and potentially dangerous keys sitting around. regards, mark hahn -- operator may differ from spokesperson. h...@mcmaster.c

Re: [slurm-users] Virtual memory size requested by slurm

Excuse me, I see that "ulimit -a" shows unlimited virtual memory size when the user runs that on terminal. However, when he puts the command in sbatch script, the value is limited to about 40GB. [shams@hpc ~]$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) un

If you look at the languages supported for server (endpoint) generation there isn't an implementation in C or even C++. The client code generator has a cpprest implementation (C++). They may have included swagger in those slides just to help people understand what a REST endpoint is. For my p
