<div dir="ltr">Hi,</div>
<div dir="ltr">As far as I understand salloc is used to make allocations but initiate a shell (whatever the sallocdefaultcommand specifies) on the node you called salloc. If you’re looking for an interactive session you‘ll probably have to use srun --pty xterm
. This will allocate the resources AND initiate a shell on one of the allocated nodes. </div>

By default salloc gives you a shell on the same node as you ran it on, <br>
with a job allocation that you can access by srun.<br>
<br>
You can read more about interactive shells here:<br>
