This report evaluates the capabilities, challenges, and future options for the Maui High Performance Computing Center (MHPCC). Located in Kihei on the island of Maui, Hawaii, the MHPCC was established in 1993 as a center within the Department of Defense's (DoD) High Performance Computing Modernization Program (HPCMP). As one of five HPCMP centers, MHPCC's primary mission is to provide computing cycles and other high performance computing capabilities to DoD's research, development, test and evaluation community. In the fall 2014, Congress asked DoD to consider ways to cut about $45 million from the HPCMP so future fiscal years could be supported entirely by the Army's programmed budget of $183 million. The findings within this report are designed to provide decisionmakers with important context about potential future missions and use cases for MHPCC as Congress, the Army, and the HPCMP work toward a solution for resolving the budget gap--
