Usage of CMS T3

CMS users now can login to the new user interface (cmsui01.ihep.ac.cn) to access the T3 resources.

Accounts

Every person have two $HOME directories, local one and Afs one. Since the quota of each user on afs is limited, please change to the local $HOME directory to submit batch jobs if your jobs are big.
  • local: /home/cms/lroos
  • Afs: /afs/ihep.ac.cn/users/z/zhangxm

Batch jobs

To submit batch jobs:
   # ssh cmsui01.ihep.ac.cn
   # cd /home/cms/YOUR_ACCOUNT
   # qsub -q cmsq YOUR_JOB_SCRIPT

To check the status of the jobs you submitted.

   # qstat -u YOUR_ACCOUNT
   # qstat -q cmsq

To retrive job outputs, it's very simple:

   #ls 
   #vi <JOBID>.OU
   #vi <JOBID>.ER
The files with .OU extension are the job outputs and files with .ER are the error logs.

Software

  • To use CMSSW, please setup the environment in your job script like the following.
   export VO_CMS_SW_DIR=/opt/exp_soft/cms
   source $VO_CMS_SW_DIR/cmsset_default.sh
   

Please feel free to give some comments.
