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 UI

First source the appropriate setup file depending on your current shell and sl version of your machine.

To check your current shell use: echo $SHELL

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

For SL4x and bash or zsh shells:
$ source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh
For SL4x and tcsh or csh shells:
$ source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.csh

For SL5x and bash or zsh shells:
$ source /data/ppe01/sl5x/x86_64/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh
For SL5x and tcsh or csh shells:
$ source /data/ppe01/sl5x/x86_64/grid/glite-ui/latest/external/etc/profile.d/grid-env.csh

Using the dq2-client

Setup the UI as mentioned in the previous section.

Again depending on SL version and shell source a setup file:

For SL4x and bash or zsh shells:
$ source /data/ppe01/sl44/i386/grid/dq2-client/setup.sh
For SL4x and tcsh or csh shells:
$ source /data/ppe01/sl44/i386/grid/dq2-client/setup.csh

For SL5x and bash or zsh shells:
$ source data/ppe01/sl5x/x86_64/grid/dq2-client/setup.sh
For SL5x and tcsh or csh shells:
$ source data/ppe01/sl5x/x86_64/grid/dq2-client/setup.csh

Then create a voms proxy

voms-proxy-init -voms atlas 

and use the dq2 Tools as needed. #

Now try these simple commands:

dq2-ls alpgen.105762.ttbarlnlnNp2_lowQ

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

dq2-ls -f alpgen.105762.ttbarlnlnNp2_lowQ
