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.

すべてのMOAS異常 →

以前は安定していたASによって発信されたプレフィックス27066 は、当社のRIPE RISコレクターから検出された別のASNによってもアナウンスされています(MOAS — Multiple-Origin AS)。多くの場合、無害(エニーキャスト、マルチホーミング、または最近の転送)ですが、ルートリークやプレフィックスハイジャックを示す可能性があるため、調査する価値があります。
