Usage of CMS T3

CMS users now can login to the new user interface ( to access the T3 resources and grid resources(including T2_Beijing).


Each IHEP cms member can log in cmsui01 with afs acount. if any problems with afs acount, please refer to Yangyi(, 6007).
When user enters, the system goes directly to afs home directory. Since the space of afs home directory is too limited(500MB), we define another $HOME directory for IHEP CMS users, which holds totally 500GB capacity in all. Therefore, users now have two $HOME directory: local one and afs one.
  • local: /home/cms/<username>
  • afs: /afs/

Grid jobs

UI( can also do the job submission to grid. You must set grid env before using grid tools
  • setenv
then you get the proxy
  • voms-proxy-init --voms cms
Now you can use crab to do the submission
  • crab -create -submit 1

Batch jobs

To submit batch jobs:
   # ssh
   # 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:

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


  • 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/

Please feel free to give some comments.
