rmcprofile-scarf

Help for running RMCProfile on the Scientific Computing Application Resource for Facilities (SCARF).

1. General Notes on RMCProfile on SCARF

1. There are, at any given time, potentially multiple versions of RMCProfile installed. To see which are currently installed, type :

   module avail RMCProfile
   

   which should yield, amongst other things, something like this :

   ------------------- /apps/eb/modulefiles/all --------------------
   RMCProfile/6.7.4    RMCProfile/6.7.7 (D)
   
   Where:
   D:  Default Module
   

   showing that there are currently two versions available, and which you get by default.

2. Instructions for use

1. Load these tools by typing:

   module load rmcprofile-tools
   

   This step will need to be performed once in each terminal session you'd like to use them.
2. Come up with your good starting configuration for your RMCProfile run on your own machine.
3. Login to SCARF and create a working root directory, for example mkdir ~/example_root
4. Copy your good starting point into a subdirectory of your working root directory. Call it something useful like "initial" or "starting". There are various ways of transferring files to and from SCARF, e.g. SAMBA or scp:

   $ scp -r /path/to/my/starting/configuration/ <username>@scarf.rl.ac.uk:~/example_root
   

5. Duplicate this directory. The tool create_duplicates.sh, which should be called from your working root directory, will do this for you. It's call looks like this:

   cd ~/example_root
   create_duplicates.sh [-h] [-n number] [-d destination] [-p prefix] initial
   

   where n is an optional number of duplicates to make (default 10), d is an optional destination to place the duplicates (default is the current directory), and prefix will be used to name all the created directories (default is 'run'). Initial is the only required argument, and it's the path to your inital directory you just made. This can be a relative or absolute path.
6. Submit your duplicates. The tool submit_duplicates.sh will do this for you. It's call looks like this:

   submit_duplicates.sh [-h] [-d directory_prefix] [-v version] stem_name
   

   which will essentially queue rmcprofile stem_name in every directory that begins with directory_prefix within your current directory (the default prefix if none is supplied is run*, which is the default output of create_duplicates.sh, above). This way you can ensure your starting copy will not be submitted. You can optionally supply a version of RMCProfile; if you do not supply a version explicitly, the default version of RMCProfile (see above) is used. Some examples of this call are:

   submit_duplicates.sh rmcsf6_190k
   submit_duplicates.sh -d sf6_on_scarf rmcsf6_190k
   submit_duplicates.sh -v 6.7.4 rmcsf6_190k
   

7. Wait for your runs to finish. You can see how many jobs you have in queues with the command squeue -u $USER or you can watch this command with watch "squeue -u $USER". Each of the directories should contain a .job file, which details the job queue submission; and a .log file, which stores the output from RMCProfile as it is run.
