1. ターミナルを起動し、計算用サーバにリモートログインする。
2. ターミナルからsshをつかってsstg1にログインする。

   $ ssh sstg1
   sstg1:~$

3. sshの終了の仕方

   sstg1:~$ exit
   $

1. co.pyをsstg1にCyberDuckを使って転送
   
2. co.pyをsstg1で実行

   sstg1:~$ ls
   Examples  co.py
   sstg1:~$ python co.py
   -591.604035353
   sstg1:~$ ls
   Examples  co.data  co.py  out.nc  out.txt

   実行する前に既にout.ncが存在するとうまく実行できないことがあるので、既にout.ncが存在しているときは、先にout.ncを削除する。

   sstg1:~$ ls
   Examples  co.data  co.py  out.nc  out.txt
   sstg1:~$ rm out.nc
   sstg1:~$ ls
   Examples  co.data  co.py  out.txt

O (8) — 6

Si (14) — 4

H (1) — 1

CO → 4+6 = 10 → 10/2 = 5 → 5+x = 8

実習の詳細はcoの全エネルギー計算を参照のこと。
