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-префикс — обнаружены ASNs с множественным происхождением

Все MOAS-аномалии →

Ранее стабильный префикс, исходящий от AS668 теперь также объявляется другой ASN (MOAS — Multiple-Origin AS), обнаруженный нашими коллекторами RIPE RIS. Часто это безопасно (anycast, многодомность или недавняя передача) — но может сигнализировать об утечке маршрута или захвате префикса, поэтому стоит проверить.
