The colors must be surrounded by quotes and have a # before the six digits as shown above.

24. 24 Tricks & Info To mount the SAN disk to your machine: Select Finder In the Finder menu select Go - Connect to Server Make sure to change the name listed to your login 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. 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. 26 Tricks & Info cd /Volumes/CERES/instrument- san/development/denise_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. 27 Tricks & Info Editing a FrameMaker document Make sure the FrameMaker document resides on your iMac Open up dingo using the Citrix server on your iMac Select Start – Programs – Adobe – FrameMaker 7.0 – 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. 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. 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: –qsub –S /bin/csh –V –o –e –q OR –qsub –S /bin/csh –V –o -j y –q

30. 30 Submitting a Job to the Cluster Examples: –qsub –S /bin/csh –V –o /CERES/instrument- san/rcf/joblogs –e /CERES/instrument-san/rcf/joblogs – q processing /CERES/instrument- san/rcf/Ed3_Repro/wrapper.sh 20070613 FM1 –qsub –S /bin/csh –V –o /CERES/instrument- san/rcf/joblogs –j y –q processing /CERES/instrument- san/rcf/Ed3_Repro/wrapper.sh 20070613 FM1
