Accounts are requested using INL’s Nuclear Computational Resource Center. To request an account, go to inl.gov/ncrc, click Make/Manage Requests, and complete the application.

HPC access is provided to users that agree to INL’s HPC policies. Once you have an account, the process differs based on if you are going to access the HPC systems from inside or outside the INL network.

On INL Network

Option 1 (preferred): OnDemand Web-Based Interface

1. Go to https://ondemand.hpc.inl.gov/
2. Enter your HPC username and password (first time users will have been emailed a temporary HPC password from [email protected]).
3. Under Clusters, select the system you want to access (If this is your first time accessing your account, and you are not prompted to change your temporary password, type “passwd” to change your password).

Option 2 (for advanced users): Terminal

1. Open your terminal application
2. SSH to preferred system (remote host). For MS Windows machines, make sure Port 22 is selected if using PuTTY, MobaXterm, etc. using the format: ssh [username]@[machinename].hpc.inl.gov
3. If this is your first time accessing your account, and you are not prompted to change your temporary password, type passwd to change your password.

Outside INL Network

Option 1 (preferred): OnDemand Web-Based Interface

1. Go to https://hpcondemand.inl.gov/
2. Enter your HPC username
3. Enter your HPC RSA SecurID PIN (created in cybele.inl.gov when you activate your RSA token) followed by your token code
4. Under Clusters, select the system you want to access.

Option 2 (for advanced users): Terminal

1. Open terminal
2. SSH [email protected]. For MS Windows machines, select Port 22 is selected if using PuTTY, MobaXterm, etc.
3. Enter your HPC RSA SecurID PIN (created in cybele.inl.gov) plus the token code.
4. SSH to preferred HPC system.
5. If this is your first time accessing your account and you are not prompted to change your temporary password, type “passwd” to change your password.

Those outside the INL network need an HPC RSA token for remote access to INL’s HPC networks.

1. Access Our System via OnDemand Web-Based Interface
2. Go to the Help drop down menu
3. Select Change HPC Password

Overleaf is a collaborative cloud-based LaTeX editor used for writing, editing and publishing scientific documents. To access Overleaf (overleaf.hpc.inl.gov), users must be in the HPC enclave.

On INL Network

1. Go to overleaf.hpc.inl.gov
2. Use your HPC username and password to login

Outside INL Network

1. Go to https://overleaf.hpcondemand.inl.gov.
2. Enter your HPC RSA SecurID PIN followed by your token code.

The Radiation Safety Information Computational Center (RSICC) at Oak Ridge National Laboratory distributes information and codes that are used in various nuclear technology applications.

1. Go to the Request History link on RSICC’s Customer Service homepage at https://rsicc.ornl.gov/CustomerService.aspx.
2. Click on the “Request History” link and enter your RSICC Pass Number and Password.
3.  After you verify the information, you will receive an email at the address listed in your account.
4. Forward this email to [email protected] indicating the package(s) you want to access.

The HPC team is available to answer questions related to running jobs, problem with jobs, storage issues, etc. To submit a ticket to HPC support, send an email to [email protected].

Researchers who use INL’s HPC resources to support their research should include the following standard acknowledgment in their publications and reports:

External users (non-INL employees) must renew their HPC account annually. The renewal process provides us with details on the work that has been accomplished using HPC, information we need to report to our DOE sponsors.
