Anyway, the problem at hand was the installation of the Torque/PBS job scheduler on a Ubuntu 14.04 LTS box .
The plan was to initially install the scheduler on a single box, acting as server, scheduler, compute node, and submission host.
Otherwise, the next step is to start the scheduler.
At this point, if you get the dreaded Unauthorized Request error, it’s critical to figure out why this is happening. We also need to create a default queue (here called ‘batch’ – you can change this to whatever you want).
The solution is simply to list the submission hosts as unqualified names.
Note that you’ll need authorised SSH keys set up for this user to allow password-less ssh.
Eventually I’ll need to set up additional boxes as submission hosts.
What made this not a fun experience was that I couldn’t find any notes from what I did the last time, which is rather unusual.
You see, every time I encounter a problem with a non-obvious solution I like to write a blog post about it.
