Content of Folders
Warning, at the moment this feature is only available on Béluga
You can get a break down by folder on how the data is consumed in your project space. That information is currently updated once a day and is stored in a portable sqlite format.
Here is a walkthrough of how to look at your data where $GROUP will be the project space folder to investigate.
Ncurse User Interface
First list all the projects that you have access to:
ls ~/projects/
def-bourqueg def-lathrop def-poq-ab rrg-bourqueg-ad rrg-lathrop
Will will take the def-poq-ab project as an example,
GROUP=def-poq-ab
duc ui -d /project/.duc_databases/${GROUP}.sqlite /project/${GROUP}
This load a browser that state the resources consumed by all files under any directory tree
Type c to toggle between consumed disk space and the number of files. Type q <esc> to quit, type h for help
If I am only interested in a /project/${GROUP} subfolder and do not want to navigate the whole tree in the ncurse ui,
duc ui -d /project/.duc_databases/${GROUP}.sqlite /project/${GROUP}/some/subfolder/
A complete manual is available with the man duc command.
Graphical User Interface
Note that on buzzy login node days, or if you have an especially large amount of files in you project space, the GUI mode can be slow and choppy. For a better experience, read the section below and run duc on you own machine.
So now you are warned, we recommend to use the standard ui mode on our clusters login nodes, duc also includes a nice graphical user interface (GUI).
First make sure you are connected to the cluster using ssh's -Y option
ssh -Y poq@beluga.calculcanada.ca
Then make GUI appear
GROUP=def-poq-ab
duc gui -d /project/.duc_databases/${GROUP}.sqlite /project/${GROUP}
You can navigate the folders with the mouse and still type c to toggle between the size of the files and their numbers
Browse faster on your own machine
First install the duc software in your local machine. Then always on your local machine, download the sqlite file from your cluster and run duc.
MYUSERNAME=poq
GROUP=def-poq-ab
rsync -v --progress ${MYUSERNAME}@beluga.calculcanada.ca:/project/.duc_databases/${GROUP}.sqlite .
duc gui -d ./${GROUP}.sqlite /project/${GROUP}
Voilà! A smooth and satisfying browsing experience.
