Copying files from Purdue IT research computing home directory to Bell
The Bell home directory and its contents are specific to the Bell cluster, and are not available on other RCAC machines. For people having access to other Community Clusters and Bell, there is no automatic copying or synchronization between main and Bell home directories. At your discretion, you can manually copy all or parts of your main research computing home to Bell using one of the methods described below.
Please note that copying may fail if the size of your research computing home directory is larger than the Bell one's quota. Please check usage and limits before proceeding!

For your convenience, a custom tool copy-rcac-home is provided to simplify at-will duplication of your main research computing home directory into Bell. The tool performs a complete 1-to-1 copy using rsync -auH (with exception of a narrow subset of system-specific service files).
To use the tool, simply type copy-rcac-home in a terminal window on a Bell front-end or compute node:
$ copy-rcac-home
This script will copy entire contents of your main RCAC
home directory into your Bell cluster's $HOME.
Note: copying may fail if the size of your RCAC home directory
is larger than your quota on the Bell one (25GB).
BEFORE PROCEEDING, please run 'myquota' command on another
cluster to see your usage there and judge whether it would fit!
Would you like to proceed? [Y/n]:
At this stage answering yes will proceed with copying, or you can respond with a no (or Ctrl-C) to cancel. See copy-rcac-home --help for more details on the tool.

Desired parts (or whole) of your research computing home directories can be copied to Bell via any of the home directories' supported transfer methods, such as SCP, SFTP, rsync, or Globus.
-
Example: recursive copying of a subdirectory from RCAC home directory into Bell home using
scp.(if you are on Bell, use other cluster name for the remote part) $ scp -pr myothercluster.rcac.purdue.edu:somedirectory/ ~/ (if you are on another cluster, use Bell for the remote part) $ scp -pr somedirectory/ myusername@bell.rcac.purdue.edu:~/ -
Example: copying using Globus.
Search collections for "Purdue Research Computing - Home Directories" and "Purdue Bell Cluster - Home" endpoints, respectively, then transfer desired files and/or directories as usual.
