HORNET – The Johns Hopkins Research Network

The Johns Hopkins Research Network (HORNET) is the high-speed network platform specially designed to support the big data needs of the Johns Hopkins research community. At the core of HORNET is a 200-Gigabit backbone that links together researchers on the JHU Homewood Academic Campus and the JHH East Baltimore Medical Campus to the big data compute and storage resources at the Maryland Advanced Research Computing Center (MARCC) and the Institute for Data Intensive Engineering and Science (IDIES). The team at MARCC is now known as Advanced Research Computing at Johns Hopkins (ARCH).

Through HORNET, the Johns Hopkins research community is able to connect to high performance computing resources from ARCH at MARCC and IDIES such as:

  • The Rockfish Cluster – ranked #414 in top500.org at 1.9TFLOPs (June 2022) and 17th among US academic institutions
  • Interactive data analysis, access to XSEDE resources, and HPC education/training resources
  • Short-term data storage and server colocation facilities
  • Managed Globus end points

HORNET also enables Johns Hopkins researchers to collaborate with more than 210 U.S. educational institutions, 70 corporations, and 45 non-profit and government agencies using Globus Data Transfer nodes and a 200-Gigabit Internet2 WAN connection.
