4. About TMUX Windows Usage

A TMUX session can have multiple Windows, and each window can be divided into multiple panes. The smallest unit we work in is actually the pane. By default, in a window, there is only one large pane that occupies the entire window area. We work in this area.

4.1 create a new pane:

  • ctrl+b c

4.2 switch windows:

  • ctrl+b p: switch to the previous one window;
  • ctrl+b n: switch to the next one window;
  • ctrl+b [index]: switch to the corresponding [index] window;
  • ctrl+b w: list all windows of this session;

  • ctrl+b l: switch between the contiguous windows;

MY NSCC USE STEPS:

  • now TMUX first (this means we create a ‘TMUX session’ first, by: tmux new -s [session_name]. )

    (we use tmux because we want to prevent our running programs from being affected by a server remote connection drop & reconnection)

  • qsub -I -l select=1:ncpus=5:mem=50gb:ngpus=1,walltime=36:00:00 -q normal -P personal-lihanzuo -N Alpaca_ATTN

  • module load miniforge3

  • conda activate [my_env]

  • nohup bash [my_python.sh] > log/output_[my_python_name].log 2>&1 & (If you don’t want to log to the logging_file, please use: nohup bash [my_python.sh] > /dev/null 2>&1 &)
