High Performance Computing Modernization Program

The HPCMP funds and oversees the operation of five supercomputing centers, called DoD Supercomputing Resource Centers (DSRCs). The centers are operated by the Engineer Research and Development Center in Vicksburg, MS, the Army Research Laboratory in Aberdeen, MD, the Naval Meteorology and Oceanography Command in Stennis Space Center, MS, the Air Force Research Laboratory in Dayton, OH, and Maui High Performance Computing Center in Maui, HI. The Arctic Region Supercomputing Center (ARSC) in Fairbanks, AK was a sixth DSRC until funding for it was discontinued in 2011. Each center hosts large-scale supercomputers, high-speed networks, multi-petabyte archival mass storage systems, and computational experts. The centers are managed by the HPCMP Assistant Director for Centers, who also funds program-wide activities in user support (the HPC Help Desk) and scientific visualization (the Data Analysis and Assessment Center, or DAAC). ==Defense Research and Engineering Network==

The Defense Research and Engineering Network (DREN) — a high-speed national computer network for US Department of Defense (DoD) computational research, engineering, and testing — is a significant component of the DoD High Performance Computing Modernization Program (HPCMP). DREN is DoD's premier wide area network (WAN) for research, test and engineering missions. DREN is a high-speed, high-capacity, low-latency, low-jitter nationwide computer network in support of the DoD's High Performance Computing, Science and Technology, Test and Evaluation and Acquisition Engineering communities. DREN connects scientists and engineers with the HPCMP's geographically dispersed high performance computing (HPC) sites, including the five DoD Supercomputing Resource Centers (DSRCs). DREN is installed at more than 210 DoD sites including research laboratories, test centers, universities, and industrial locations throughout the United States (including Hawaii and Alaska). The fourth generation DREN network (DREN 4) is provided under a commercial services contract awarded to Verizon in 2021. DREN has been awarded in the past to Lumen (DREN 3), Verizon (DREN 2), and AT&T (DREN 1). DREN service providers typically build DREN as a virtual private network overlay on their commercial network infrastructure. Capabilities provided by DREN 4 include digital data transfer speeds ranging from 1 Gbit/s through 100 Gbit/s. DREN 4 is an IPv6 network, with support for legacy IPv4. The HPCMP is currently in the process of building out DREN 4 which will ultimately replace DREN 3 when fully tested in 2022. The two networks will run in parallel for about one year while the 210 sites are transitioned from DREN 3 to DREN 4. In 2003, DREN was designated the Department of Defense's first IPv6 network by the Assistant Secretary of Defense for Networks & Information Integration. Since that time, DREN has been a pioneer within the DoD and US Federal Government for IPv6 deployment, running both IPv4/IPv6 dual stack and IPv6-only networks. DREN provides an extensive IPv6 Knowledge Base containing best practices and lessons learned, available at no charge on the HPCMP website. Other research networks of interest: • CANARIE • DANTE • Energy Sciences Network • High Performance Wireless Research and Education Network • Internet2 Network • NASA Research and Engineering Network ==Software applications==

In addition to supercomputers and the national wide area research network, the HPCMP funds software applications that help the DoD achieve its research objectives by ensuring that important DoD applications run effectively on the large-scale supercomputers it deploys. HPC Software Applications Institutes HPC Software Applications Institutes, or HSAIs, are cross-disciplinary projects funded by the HPCMP but executed in the DoD labs. The HSAI program both develops tools to solve important computational problems facing the DoD and build organic HPC expertise within the department. User Productivity Enhancement and Training (PET) The High Performance Computing Modernization Program's (HPCMP) User Productivity Enhancement and Training (PET) program gives users access to computational experts with experience spanning a wide variety of HPC technical areas. The PET Team is available to help HPC users become more productive using HPCMP resources with the goal of expediting milestones and reducing overall costs related to technological development to DoD users. In addition to internal expertise, the PET Team also provides virtual training on effective usage of software, hardware, networking, data transfer, data storage, and visualization of data. PET facilitates and promotes the transfer of scientific and technical knowledge between HPCMP users and the broader computational communities, including DoD and other federal agencies. Help in specific Technical Thrust Areas (TTAs) provide a wide range of expertise including, but not limited to, new delivery methods, emerging hardware exploration, High Performance Data Analytics (HPDA), debugging software, performance improvement with user codes, scalability issues, and porting of software to emerging hardware. PET offers three modes of support depending on the type, duration, and level of user support required: • Mission Projects (MPs): Mission Projects are designed to assist users with solving complex issues in mission-critical areas. MPs will last anywhere from 1 to 12 months in duration. PET Team scientists will advise and assist in developing, applying, and/or using algorithms and in maximizing usage of existing software. • Special Projects (SPs): Concentrated efforts involving separately funded projects that may include PET Team support staff or other subcontractors for project/user specific challenges. • Training: Trains the HPC community in applicable tools and technologies using the latest collaboration, distance learning, and training technologies. Computational Research and Engineering Acquisition Tools and Environments CREATE is a federated program approved in the DoD 2006 Program Objective Memorandum (POM) process, with funding starting in 2008. The CREATE Program is part of the Tri-Service Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP). The HPCMP is executed by the US Army Corps of Engineers (USACE) Engineer Research and Development Center (ERDC) Information Technology Laboratory (ITL) in Vicksburg, Mississippi. The charter of CREATE is to reduce the cost, time, and risks of DoD acquisition programs by developing and deploying multidisciplinary, physics-based software applications for the design and analysis of military aircraft, naval ships, and radio frequency antenna systems (expanded to include ground vehicles in 2012) by DoD engineering organizations.

The following table summarizes the chronology of program directors. ==The HPCMP in the DoD Budget==

Since FY2012, the HPCMP's base funding has been provided on two lines in the Army budget, which is itself a portion of the Department of Defense Budget submitted each year by the President and approved by Congress. PE 0603461A provides for RDT&E funds that operate the centers and DREN, and funds R&D efforts in support of program goals. Line item number B66501 (line 103, BA 02, BSA 92) provides procurement funds for the annual purchase of new supercomputing hardware (both supercomputers and related systems). Prior to FY2012, the HPCMP's RDT&E funding was provided on PE 0603755D8Z, while procurement was funded on PE 0902198D8Z (P011). The following table summarizes requested and committee-approved funding amounts for the RDT&E portion of the program for the most recent federal fiscal years (procurement funding, which is supplied on a different line in the federal budget, is not included in this table). The temporary change in Program Element number for FY2004 reflects a planned transition of the program from management by the Office of the Secretary of Defense to the Air Force; this transition did not ultimately occur. ==References==
