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 Préfixe MOAS — plusieurs ASN d'origine détectés

Toutes les anomalies MOAS →

Un préfixe auparavant stable, originaire de l'AS668 est maintenant également annoncé par un autre ASN (MOAS — Multiple-Origin AS), détecté par nos collecteurs RIPE RIS. Souvent bénin (anycast, multi-homing, ou un transfert récent) — mais cela peut signaler une fuite de route ou un détournement de préfixe, il est donc utile de l'inspecter.
