Note:

The Data Capacitor II (DC2) high-performance file system was retired from service on December 11, 2020. IU research supercomputer users can create accounts on Slate or request project space on Slate-Project. If you have questions or issues regarding the DC2 file system retirement, contact the UITS High Performance File Systems (HPFS) team.

The Data Capacitor II (DC2) high-performance file system provides scratch directories and project space for Indiana University research supercomputer users. In the following examples, replace username with your IU username or project_name with the name of your project:

Locate your DC2 scratch directory or project space: On the research supercomputers, your DC2 scratch directory will be mounted at /N/dc2/scratch/username. If you have project space, it will be mounted at /N/dc2/projects/project_name.
View permissions: To view the permissions for files and directories in your DC2 scratch directory or project space, use the ls -al command; for example:
```
  ls -al /N/dc2/scratch/username
  
  ls -al /N/dc2/projects/project_name
```
The output also will include owner and group information for the files and directories at those locations.
Determine how much space you're using: To determine how much space you're using in your DC2 scratch directory or project space, use the du -sh command; for example:
```
  du -sh /N/dc2/scratch/username
  
  du -sh /N/dc2/projects/project_name
```
