Grid Services

Grid User Interface

Every PPE desktop (both SL4x or SL5x) can act as a EGEE gLite UI. The User Interface (UI) tools, dq2-client and GANGA are installed on SL4x desktops in /data/ppe01/sl44/i386/grid. For SL5x desktops the User Interface (UI) tools, dq2-client , but not GANGA are installed in /data/ppe01/sl5x/x86_64/grid

Using the dq2-client

Depending on the SL version and shell source a setup file:

Then source the corresponding UI setup file (see section below).

Then create a voms proxy

voms-proxy-init -voms atlas 

and use the dq2 Tools as needed. #

Now try these simple commands:

dq2-ls mc09_7TeV.105003.pythia_sdiff.merge.NTUP_MINBIAS.e514_s764_s767_r1229_p137_tid130190_00

and to show the individual files (This may not work on SL5 machines)

dq2-ls -f mc09_7TeV.105003.pythia_sdiff.merge.NTUP_MINBIAS.e514_s764_s767_r1229_p137_tid130190_00

Using the UI

Source the appropriate setup file depending on your current shell and sl version of your machine. If you are using the dq2 client this needs to be done after sourcing the dq2 client setup file.

To check your current shell use: echo $SHELL

To check the version of SL use: cat /etc/redhat-release
