Helix Systems accounts are restricted to NIH employees and contractors.
Helix accounts cannot be shared. Each Helix user needs their own Helix account.

How to get an account on any of the Helix Systems

To access any of the Helix Systems machines, you need a Helix Systems account. Your Account Sponsor can request one by using the WebSponsor online form at http://websponsor.cit.nih.gov/nihlogin. (The Account Sponsor is the person in your lab or office who is responsible for the CIT account to which your Helix account will be billed). If you, your lab or office do not have a CIT account, you will need to complete the CIT account authorization (http://support.cit.nih.gov/accounts/) to set one up.

Who is my Account Sponsor

If you don't know who your Account Sponsor is, go to the webpage at http://silk.nih.gov/locator, select your Institute/Center from the Account Sponsors and Alternates list, and click the Display button. This will display all the Account Sponsors for your Institute/Center, and you may be able to identify the appropriate person from the list. Otherwise, talk to your supervisor, or call the NIH Help Desk at 301-496-4357 for assistance.

The Helix User registration and CIT account authorization forms are also available from the NIH Help Desk, which can be reached at 301-496-4357. Fax your completed form to (301) 402-7349.

Once your request is processed by the Customer Accounts Office, a copy will be sent to you with your username and password. If you have questions about the status of your request, call the NIH Help Desk at (301) 496-4357 or contact them online.

What can I do with a Helix Account

A Helix Account entitles you to access our scientific databases and applications and resources (http://helix.nih.gov/Applications). The different machines are intended for different purposes; visit Helix Systems at http://helix.nih.gov for more info; you can also contact the Helix staff (email: staff@helix.nih.gov) if you are unsure of which machine to use.

• Helix is the front-end machine, and is used for interactive computing.
• Biowulf (http://biowulf.nih.gov) is a Linux cluster with over 3500 processors for parallelized scientific applications. Since Biowulf is a specialized system, users need to provide some information about their requirements for Biowulf. If you want to use Biowulf, fill out the form at http://biowulf.nih.gov/account_request.html.
