  name for manila/corregidor and fill in your
  password and click Connect.
• A Finder window will appear and you should then
  select CERES
• An icon with a globe and CERES underneath will
  appear on your desktop and you now have access to
  your directories on the SAN.

25
Tricks Info

• To edit a file using CarbonEmacs
• In your .cshrc file add the following line
• alias emacs open a /Applications/Emacs.app
• This will allow you to open emacs directly from a
  terminal window on your machine.
• Open a new X11 terminal window on your machine

26
Tricks Info

• cd /Volumes/CERES/instrument-san/development/denis
  e_area/rel4/rcf
• emacs CER1.1P3_input_find.csh
• This will bring up an emacs window, remember that
  the normal menu you are used to seeing on emacs
  on thunder will be up at the top of your screen
  on your iMac. You will also notice if you try to
  emacs the same file on thunder it will tell you
  that the file is locked.
• You may also use nedit or any other editor that
  you prefer, even vi.

27
Tricks Info

• Make sure the FrameMaker document resides on your
  iMac
• Open up dingo using the Citrix server on your
  iMac

  Adobe FrameMaker 7.0
• In FrameMaker select File Open C on Client
  (V) select file you want to edit
• If the Start button does not show up on your
  dingo server, select MyComputer from the desktop
  and then select the FrameMaker file from there
  starting from C on Client (V )

28
Submitting a Job to the Cluster

• You may want to look at an example of a script
  that submits a set of jobs to the cluster where
  each creates the PCFin, PCF and runs the job on a
  Node
• /CERES/instrument-san/development/denise_area/mac
  /rcf/jobSubmitter_p
• This script requires that you have a couple of
  directories and other scripts in your rcf area
  joblogs/ Ed3_Repro/
• You can copy this script and those in Ed3_Repro
  and edit them to work in your area. Remember
  that you must source your environment when you
  submit a job to a cluster node it does not have
  the environment that you have on manila carried
  over to the cluster node, it is a NEW machine, so
  nothing is set up until you do it in your script.
  This is the same as how it works in production
  at ASDC.

29
Submitting a Job to the Cluster

• Things you will need
• Account on manila/corregidor, at this time you
  can only submit jobs from these two machines
• wrapper script
• joblogs directory for your wrapper.sh.oxxxxx
  wrapper.sh.exxxxx files
• Command to submit a job
