File Storage
User home directories are linked from ENGNAS to /home/(username). These are the same shares users access as their “X: drive” on BU managed Windows systems. The quota for X: Drives is fixed at 10 GB.
Research group shares are located at /ad/eng/research/eng_research_(groupname). These shares are also accessible from individual Windows, Linux, and Mac clients on and off campus. Shares are also available on the Shared Computing Cluster (SCC) at the same path.
The storage capacity of the research shares is expandable on request (not X: Drives). For help with setting up, accessing, or managing permissions on your network storage, contact ENG-IT at enghelp@bu.edu.
| Location | Description |
| /ad/eng/users | All Engineering home directories, organized by first and second letter of each username |
| /ad/eng/research | Research group storage, listed by eng_research_(groupname) |
| /ad/eng/projects | Non-research project group storage, listed by eng_proj_(groupname) |
| /ad/eng/courses | Course storage, organized by department |
Executables
Many executables for installed software are available on login in the default PATH. We make many other packages available via the Environment Modules system. Use the following command to list the currently available packages
$ module avail
These locations have read-only access available for both authenticated users and batch jobs.
| Location | Description |
| /ad/eng/bin | Links to available executables, also organized by architecture (32 and 64) |
| /ad/eng/opt | Installed software directories, also organized by architecture (32 and 64) |
| /ad/eng/lib | Installed software libraries |
| /ad/eng/sbin | Executables for system use, not generally of interest to users |
| /ad/eng/etc | Shared system configuration data, not generally of interest to users |
To add the appropriate directories to your PATH variable on a system without the default Engineering Grid profile, issue this command:
$ source /ad/eng/bin/add_bin.sh
You’ll then be able to issue commands like comsol or python-anaconda without specifying the full paths under /ad/eng/bin/ and /ad/eng/bin/64/.
Deprecated
- For temporary, read/write scratch space during compute jobs, users can create a directory /mnt/nokrb/(username)/ with an adjustable quota starting at 2 GB (see the Engineering Grid instructions for more information).
