Helix Systems Policies

Who May Use the NIH Helix Systems

Accounts on the NIH Helix systems are for the use of researchers in NIH intramural research programs.

NIH Volunteers can maintain Helix/Biowulf accounts for the duration of their NIH status, but will get access to fewer Helix Systems resources than NIH employees and contractors.

User Responsibilities

The NIH Helix systems are for appropriate government use only

System resources are for the work-related use of authorized users only.

E-Mail

The NIH Office of Information Resources Management considers chain letters, joke messages, and ads to be inappropriate activities, subject to disciplinary action, according to an OIRM policy memo.

Internet

The NIH Senior IRM Official released a policy memo on December 8, 1995 stating "use of the NIH Internet services is limited to activities that support the NIH mission," subject to disciplinary action including suspension. Also see the HHS IRM Policy (2003) policy for personal use of IT resources.

Data Content

Helix users are forbidden from transmitting or storing any Personally Identifiable Information (e.g. patient data containing names or social security numbers) or sensitive data anywhere on the Helix systems, including their home and data directories.

Read the announcements!

Users are responsible for reading the system messages and announcements. These will appear as messages during login, and will also be sent to all Helix users by email. [Archive of Helix & Biowulf messages]

Account sharing among multiple users is prohibited

A separate Helix account must be set up for each user.

Access to data and applications is restricted

Please do not access files or directories belonging to another user without explicit permission.

System Usage

As the frontend machine for the Helix Systems, Helix is not intended for major computational tasks. It should be used only for reading mail via pine, administrative tasks like moving/renaming/copying files, and running short interactive jobs. All memory-intensive (> 2GB) or cpu-intensive (> 4 hrs) or large numbers (> 2-3 simultaneous) jobs should be performed on the Biowulf cluster. Please contact the Helix staff (staff@helix.nih.gov, or 301-496-4825) if you have questions about the appropriateness of your job for a particular platform, or need more information about how to run your job.
