User home directories are linked from ENGNAS to \/home\/(username)<\/tt><\/strong>. These are the same shares users access as their “X: drive<\/b>” on BU managed Windows systems. The quota for X: Drives is fixed at 10 GB<\/strong>.<\/p>\n

Research group shares are located at \/ad\/eng\/research\/eng_research_(groupname)<\/tt><\/strong>. These shares\u00a0are also accessible<\/a> from individual Windows, Linux, and Mac clients on and off campus. Shares are also available on the Shared Computing Cluster (SCC)<\/a>\u00a0at the same path.<\/p>\n

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<\/a>.<\/p>\n

Executables<\/h2>\n

Many executables for installed software are available on login in the default PATH. We make many other packages available via the Environment Modules<\/a> system.\u00a0Use the following command to list the currently available packages<\/p>\n

$ module avail<\/pre>\n
These locations have read-only access available for both authenticated users and batch jobs.<\/p>\n

To add the appropriate directories to your PATH variable on a system without the default Engineering Grid profile, issue this command:<\/p>\n
$ source \/ad\/eng\/bin\/add_bin.sh<\/pre>\n
You’ll then be able to issue commands like comsol<\/tt> or python-anaconda<\/tt> without specifying the full paths under \/ad\/eng\/bin\/<\/tt> and \/ad\/eng\/bin\/64\/<\/tt>.<\/p>\n
