What is GRACE?
Glue Research and Academic Computing Environment (GRACE) is available to instructors, students, and researchers.
Starting Spring 2010, OIT will no longer offer TTCLASS file space. Former TTCLASS Users will need to request GRACE class access.
GRACE can be accessed with the TerpConnect File Manager, WebDAV, AFS or with Terminal applications.
GRACE Documentation :
- Getting Started with your GRACE account
- Connecting to your GRACE account with the TerpConnect Filemanager
- Connecting to your GRACE account with Terminal Applications
- Connecting to your GRACE account with WebDAV
- Connecting to your GRACE Account with SFTP
- Troubleshooting your GRACE account
Class File and Directory Structure
When you request space for your class the following directory will be created (for example; CMSC 123, Fall 2008, section 0101 may have the path):
/afs/glue.umd.edu/class/fall2008/cmsc/123/0101Under this several directories will be created
(this chart is based on http://www.grace.umd.edu/instructors/filesystem.html):
| Former TTCLASS Directory | GRACE directory | student permissions | instructor permissions | purpose |
| notes | public | read | read/write | place for instructor to post any materials for students to have access to |
