Welcome to the Scientific Data & Computing Center (SDCC) at Brookhaven National Laboratory.


One example of Brookhaven’s computing expertise is the RHIC & ATLAS Computing Facility (RACF). Formed in 1997 to support experiments at RHIC, Brookhaven’s flagship particle collider for nuclear physics research, the RACF is now at the center of a global computing network connecting more than 2,500 researchers around the world with the data from RHIC and the ATLAS experiment at the Large Hadron Collider in Europe. This world-class center houses an ever-expanding farm of computing cores (50,000 as of 2015), receiving data from the millions of particle collisions that take place each second at RHIC, along with petabytes of data generated by the LHC’s ATLAS experiment—storing, processing, and distributing that data to and running analysis jobs for collaborators around the nation and the world. The success of this distributed approach to data-intensive computing, combined with new approaches for handling data-rich simulations, has helped establish the U.S. as a leader in high-capacity computing, thereby enhancing international competitiveness.

How to apply for use of SDCC resources.

Users wishing to access SDCC resources must first submit a proposal through the BNL PASS (Proposals, Allocation, Safety, Scheduling) system. Proposals are evaluated by a review committee, taking into account scientific merit, institutional priorities, resource availability and the likelihood of contributing to continued growth of BNL's computational capabilities.


After an access application has been approved, users can apply for an account.

An active and valid BNL Life or Guest Number is required in order to gain approval for an SDCC computing account. Obtain a guest number here.

  1. Why is this necessary?
    In order to comply with stricter U.S. Department of Energy requirements, we are requiring all of our active accounts to have active Life or Guest Numbers and to have completed CyberSecurity training.
  2. CyberSecurity Training
    Please visit the BNL Training site to complete the relatively short CyberSecurity Training course, which requires your Life or Guest Number for the purpose of recording your progress through the course.
  3. Extending or Reactivating Guest Numbers
    The status of your Brookhaven National Laboratory guest appointment depends on your intention to return to BNL. Please follow the appropriate instructions below:
    1. If you do not plan to return to BNL, please inform us via email and include your name and guest number in the message.
      In addition, please return your BNL ID card to:
      Police Headquarters
      Brookhaven National Laboratory
      Upton, NY 11973
    2. If you do plan to return to BNL, please do the following:
      1. Visit the BNL Guest Extension Form and follow these instructions. This is a secure web site.
      2. Verify that the information listed in the left column is accurate, and make any necessary corrections in the right-hand column.
      3. In order for us to insure your approval for on-site access is completed in a timely manner, we ask if you could enter an anticipated arrival and departure date. We understand this is only an estimate; your actual dates are entered on the check-in/check-out form below.
      4. When all fields are complete, click Send.

Obtaining a New User Account

In order to obtain a new SDCC computer account, you must:

  1. Read and consent to Brookhaven National Laboratory 's Computer Use Agreement by completing the BNL Computer Use Agreement training course.
    Please contact the RHIC & AGS Users' Center with any questions.
  2. Fill out the Computer Account Request Form.
    Once you have submitted the request form, the SDCC will verify your eligibility for a computing account.
    You will be notified, via the email address that you have provided, when your account has been activated.
    All invalid requests will be discarded.


How to gain access to SDCC clusters and resources:

After obtaining an account, please contact your respective Liaison to request cluster access. SDCC Liaisons must submit names of all approved users via our ticketing system.

Once approved, upload your public SSH key to the facility via this form.

Enable SSH agent forwarding, and use your uploaded SSH key to log into either of the following SDCC gateways:

  • ssh01.sdcc.bnl.gov
  • ssh02.sdcc.bnl.gov

Institutional Cluster and Sky Cluster access

From a gateway, SSH to either of the following institutional cluster submit nodes:

  • icsubmit01.sdcc.bnl.gov
  • icsubmit02.sdcc.bnl.gov

Cluster has a debug partition used for debug/interactive sessions

KNL Cluster access

From a gateway, SSH to either of the following KNL cluster submit nodes:

  • knlsubmit01.sdcc.bnl.gov
  • knlsubmit02.sdcc.bnl.gov

Cluster has a debug partition used for debug/interactive sessions

Shared Cluster access

From a gateway, SSH to either of the following shared cluster submit nodes:

  • spool0001.sdcc.bnl.gov
  • spool0002.sdcc.bnl.gov


Storage solutions offered by the SDCC:


BNLBox is a cloud storage service that enables BNL users to store their scientific data and documents locally, and makes it accessible and available from anywhere om the worls with internet access. The files stored in BNLBox can be easily shared with other BNLBox users, as well as any external collaborators.

See this page for more information about BNLBox, including how to obtain access.


Ticket system

For direct support, send an email to one of the following:

  • Application support: help with software applications, optimization, performance, and debugging.
  • Cluster support: help with hardware, OS, batch system, storage, group quotas and access, and connectivity.
  • User account support: help with user accounts, passwords, permissions, login, and SSH.
For other issues, or more details about support, please see this information on our RT ticket system, and create a help ticket in the appropriate queue.

Mailing list

An SDCC mailing list is open to all current and future stakeholders and their user communities. The list is used to communicate operational issues concerning systems operated by the SDCC, such as the Institutional, KNL, LQCD, and Simons Foundation clusters. This list is moderated to reduce the potential for spam.

See this page for more information and to subscribe to the mailing list.
