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


One example of Brookhaven’s computing expertise is the Scientific Data & Computing Center (SDCC). Formed in 1997 to support experiments at RHIC, Brookhaven’s flagship particle collider for nuclear physics research, the SDCC 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.

CyberSecurity Training:

  • In order to comply with U.S. Department of Energy requirements all of our active accounts are required to have active Life or Guest Numbers and to have completed CyberSecurity training found at the BNL Training site http://training.bnl.gov.

Computer Use Agreement Form:

Obtaining a User Account:

  • When you have completed the above steps 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 used when signing up, when your account has been activated. All invalid requests will be discarded.


In order to use/access the SDCC resources you will need a valid allocation.

To have a valid allocation you need to fulfill one of the following:

  • Access to an allocation of computational or storage resources as a member of a project account
  • Commercial allocation by contacting CSI
  • Apply for a free allocation at: PASS
    • 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.

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

Storage solutions offered by the SDCC:


BNLBox site
  • BNLBox is a cloud storage service that enables BNL users to store their scientific data and documents locally, and makes them accessible from any device 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.

Cluster Storage

  • Using the Institutional Cluster (IC), including information about central storage, backups, and transfers
  • See this page for more information about Cluster Storage and 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.
