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.

⚠ 1 MOAS-Präfix — mehrere Origin-ASNs erkannt

Alle MOAS-Anomalien →

Ein zuvor stabiles Präfix, das von AS668 wird jetzt auch von einer anderen ASN angekündigt (MOAS — Multiple-Origin AS), erkannt von unseren RIPE RIS Kollektoren. Oft harmlos (Anycast, Multi-Homing oder eine kürzliche Übertragung) — aber es kann ein Route Leak oder Prefix Hijack signalisieren, daher ist eine Überprüfung sinnvoll.
