Marlowe User Filesystems
There are multiple filesystems available to end users on Marlowe.
/users/
/users/ is where a user’s home directory lives. It is directly mapped to the $HOME variable, so whenever you run cd ~ or cd $HOME you will be sent to /users/<Your-sunet-ID>.
For example, if my sunetID was bob, then my home directory on Marlowe would be /users/bob
Each directory in /users/ is unique to that user.
/users/ is backed up once every 24 hours.
/projects/
/projects/ is the filesystem where all allocation project directories live.
When you are given an allocation, you are given a project ID. This project ID is also your directory in /projects/
For example: If your allocation’s project ID was m231631, then your allocation’s project folder would be /projects/m231631/
Directory quotas in /projects/ vary depending on the amount approved in the allocation.
Every user added to an allocation shares the same /projects/ folder. So bob and amy in project m231631 would both have files in /projects/m231631/, but greg in project m402630 would have files in /projects/m402630
/projects/ is backed up once every 24 hours at 9:15pm.
/projects/ are mounted as needed, so your specific folder may not show up when you login initially. cd to your project directory and it will show up until you log out.Here is an example:
/scratch/
/scratch/ is the lustre filesystem meant (as the name implies) to be used as scratch storage.
Much like in /projects/, your /scratch/ folder corresponds to your project ID. /scratch/m231631,/scratch/m402630, etc.
/scratch/ is not backed up. Unlike /users/ and /projects/, /scratch/ is not replicated.
Allocations are given 20TB is /scratch/ by default.
