How to use speclab.seas.upenn.edu
Some courses involve computer assignments that are not allowed in the labs or on Eniac, because they would compromise the security or reliability of the machines. Students in these courses use speclab for these assignments.
Access to Speclab is not available to all SEAS students, only those registered for certain courses. CETS does not provide access to Speclab for individual students.
How to access speclab
The speclab machines can be accessed only from SEASNet using SSH (not telnet):
Where username is your SEAS account.
Alternatively, use the Speclab monitoring page to see a list of available machines and then SSH to a specific speclab machine.
Running GUI applications on Speclab
Storage space on speclab
Your SEAS home directory
will be mounted automatically when you log in to speclab. If you are working with especially large data,
unsuitable for storing in your home directory, consider using the /scratch partition.
Files saved to
/scratch may be deleted at any time, so don't store
anything there that can't be re-created easily.
Common reasons for speclab access problems
- You are not enrolled in a course which uses speclab.
- You just recently enrolled in the class using speclab. It can take up to 48 hours from when you enroll until you have access to speclab.
- You are trying to connect to speclab from a machine outside of the SEAS network. If you do not have a connection to SEASNet, first SSH to a machine that does (such as eniac), then SSH to speclab from there.
