Ethical Guidelines
All users must follow the Institute's
ethical guidelines.
In particular, passwords must NOT be shared with anyone! Every individual
with access to the facility should have his/her own user account and
password.
Privacy
The default file permissions for the new user is read/write/execute
by the user and read/execute by the user's group. A principal investigator has the right to access data and files in his/her research group. In the event that the P.I. has difficulty doing this, he or she may contact the Research Programs Administrator or the Head of Technical Support.
Technical support staff do not read a user's email or files or alter them without the user's permission except in cases of emergency and only within the scope of administrative responsibilities.
Background Jobs
All background jobs must be submitted through the
Distributed Queueing System (DQS). Jobs submitted through DQS are
suspended when someone is actively using the console. The technical
support staff reserves the right to kill any background job not
submitted through DQS which adversely affects a user at the console.
There will be limits on amounts of memory and the number of CPU hours
permitted. See our
DQS web pages for more information on how to
use DQS and the available queues.
Disk Quota
Each user is allocated a limited amount of home
directory space (currently 100 MB). Home directories are backed
up nightly. If additional space is needed please contact
help@msi.umn.edu.
Temporary Disk Space
The local disk space in /usr/tmp will be cleared weekly. For
longer term temporary space, /wrk and /wrk2 are available.
Any file older than
and unchanged for 30 days will be deleted. Touching files will not
effect the deletion date. The technical support staff will
work with users to accommodate longer term, large disk requirements as
resources permit. Temporary disk space (/usr/tmp and /wrk)
are NEVER backed up by technical support staff.
Cross-Mounting File Systems
The SDML will not export any of our file systems, but we will mount
a researcher's file systems onto the SDML systems. However, the SDML will
not change the researcher's default UIDs or GIDs to do so.
Unattended Workstations
Users must log out of the console whenever they leave the workstation for
more than a few minutes.
Reserving Workstations
Some machines may be reserved for 2 hour periods. For
example, a researcher who wants to work with a visitor may want to
reserve a machine to guarantee access at a certain time. This is only
on a case-by-case basis. For example, a user may not reserve a
particular workstation every day between 2:00-4:00 pm.
