This README file explains and demonstrates the procedure for creating the necessary Linux configuration file to facilitate file syncing between a folder on your PC with another on the SCC.

Upon downloading and running an m-file, two customized macros, cp2scc and cp2pc, will be created. The cp2scc copies (or sync) from a folder (whose path and name you specified while running the m-file) on the PC to a designated folder on the SCC. Similarly, the cp2pc lets you copy from the SCC to the PC.

Note that while a MATLAB example is given, the procedure in general is not limited to MATLAB. Note also these notations throughout this page:

• /home/mobaxterm or [...] ->      PC window prompt
• scc1:~ $      SCC prompt
• >>      MATLAB workspace prompt

MobaXterm basics

Before we go on to the main topic, let's review the following MobaXterm file structure layout and naming. When you launch MobaX by clicking on the MobaX icon, the only window tab that appears, by default, is your /home/mobaxterm folder (the tab itself indicates that).

• Your PC's C:\Windows is accessible in MobaX with

   [...] -> cd /drives/c/windows

• You can find out what drives are mounted on your PC with

   [...] -> ls /drives
   c  p  q  s  w  x

• To access the c drive, enter

   [...] -> cd /drives/c

• Navigate to find your matlab folder on the PC, mark that. You will need that path in the following. Under MS Windows, the C drive is represented as C:. In MobaXterm, the equivalent is /drives/c. Except for the stated prefixes, all sub folders follow closely between both representations.

Creation of .bash_profile Configuration file for /home/mobaxterm

1. Find out where your local PC matlab folder path is in MobaXterm representation. It should have the general form of /drives/c/windows/....
2. On the SCC, decide where you want to copy your PC's matlab folder over. (/usr3/graduate/... or /project/project-name/userID/...)
3. Go to your SCC home directory (you may already be there)

   scc1:~ $ cd

4. Copy a folder

   scc1:~ $ cp -rp /project/scv/examples/matlab/misc/file_sync .

5. A new folder file_sync below your home directory has been created. Let's go there

   scc1:~ $ cd file_sync

6. Launch matlab from file_sync

   scc1:~ $ matlab&

7. This folder contains two files: makeMacros.m, README.html. Lets confirm that with

   >> ls
   README.html*  makeMacros.m

8. Run the m-file to generate necessary files

   >> makeMacros    % run this on the SCC

   Answer 3 questions (source and destination path and file names, userID on the SCC). The folder should now contain

   README.html*  cp2pc         cp2scc        makeMacros.m  move2bin*

9. Next, switch to the /home/mobaxterm tab
10. Copy the above listed files on the SCC by cut-and-paste the below line at the mobaxterm system prompt ([...] ->)
    Don't forget to replace your-userID with your SCC login name before pressing Enter.

    [...] -> scp -rp your-userID@scc1.bu.edu:~/file_sync/. /home/mobaxterm

11. Execute the just generated move2bin script. It performs a few operational tasks

    [...] -> ./move2bin

12. Make sure that things are as they should be; verify that you can access cp2scc from wherever you are with this command

    [...] -> which cp2scc

    It should tell you that it resides in /home/mobaxterm/bin.

How to use cp2scc, cp2pc

• For users who develop and update matlab codes primarily on the PC and use the SCC mainly for running production jobs, cp2scc is recommended. The easy syncing will ensure that the folder in which your matlab code is based is as up-todate as the corresponding one on your PC.
  [...] -> cp2scc        copy (from PC) to SCC
  
  
• On the other hand, to copy output from the SCC back to the PC, use this instead
  [...] -> cp2pc        copy (from SCC) to PC
  
  
• The two macros are hardwired to the specific folder, respectively, on the PC and SCC. If you need to sync with other folders, the best way is to go to the bin directory, then make copy the two existing macros and change folder names as appropriate.
