About High Performance Computing Modernization Program
The United States Department of Defense High Performance Computing Modernization Program (HPCMP) was initiated in 1992 in response to Congressional direction to modernize the Department of Defense (DoD) laboratories’ high performance computing capabilities. The HPCMP provides supercomputers, a national research network, high-end software tools, a secure environment, and computational science experts that together enable the Defense laboratories and test centers to conduct research, development, test and technology evaluation activities.
