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 this, though
srun -t 08:00:00 --ntasks-per-node=40 --pty -p batch ../splitscreen
srun -t 08:00:00 --ntasks-per-node=40 --pty -p batch /bin/bash -i -l
-c ../splitscreen
it doesn't look so good -- text that should be in the righthand window
starts writing in the lefthand window instead, and the lefthand window
contents don't show up.
I believe "screen" uses the "curses" library, or at least something
similar, and I'm guessing that the cursor placement is getting garbled
somehow.
Are there any special "srun" settings that I can use to straighten this
out? Again, if I use an ssh connection instead, it works perfectly.
I could file a bug with SLURM, but am thinking (hoping) that maybe I'm
just not using it right.
Thanks,
Carl
