Open Research Service

Welcome to the DoD HPCMP Open Research Service (ORS). The Open Research Service provides for computationally based science and engineering in support of the DoD. Systems are provided for high performance computing and utility computing. These systems operate entirely at the Unclassified level, with neither sensitive nor classified data or applications.

Obtaining an ORS Account

The process of getting an ORS account begins with getting an account on the HPCMP Portal to the Information Environment, commonly called a "pIE Account." If you do not yet have a pIE User Account, please visit Obtaining An Account and follow the instructions there. If you need assistance with any part of this process, please contact the HPC Help Desk at If you have an active pIE account, you may proceed to the next steps.

HPCMP Open Research Service Account Request

Please email your Open Research Service request to All requests will take a minimum of 24 hours to process once received. Request fulfillment time will vary based on the specific request and lead time required. For questions, please e-mail
