*Setting up isotope2.aori.u-tokyo.ac.jp [#n1343bf2]

**specification [#od3291a8]
 Name: isotope2 (renewed on 2016)
 Cluster system
// Headnode: Xeon X5680 (3.3GHz, hexa core) x2
 Headnode: Xeon E5-2640 V4 2.4GHz 10Core×2
 Compute node: 
  Xeon X5690 (3.46GHz, hexa core) x2x12
  Xeon E5-2697V2 (2.7GHz, 12Core) x2x2
 Network: InfiniBand QDR (MPI/NFS)
 OS: RedHat Enterprise Linux 5 (Server)

** OS [#oc0ca5f6]

** softwares [#o93ecf92]
大抵はisotope2からそのまま引き継げでいる。詳しくは[IT memo/linuxmemo3]参照。

** ganglia [#s0a3fe41]
- ノード負荷状況のモニター。 から見れる(CCSR内のみ)。

* Basic rules [#qb8c8ad5]
- Use /dataX directories. Minimize to use /home directory.
- Use PBS (computing nodes) for long job. Head node (isotope2) is interactive use only. 

* Getting start [#k0cbab80]
- change your password
 $ passwd
- change your login shell to /bin/tcsh (if your default is bash)
 $ chsh
- copy /home/kei/.cshrc in your home directory 
 $ cp /home/kei/.cshrc ~/
- make your public key for isotope2
 $ ssh-keygen -t rsa
 (do not input passphrase)
- save your id_rsa.pub as authorized_keys
 $ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
 $ chmod 600 ~/.ssh/authorized_keys
- go to your working directory (/dataX/yyyy) and work. 
 $ cd /dataX/yyyy
