A large contingent of Team ADNET SESDA 3 scientists and engineers participated in the 2014 American Geophysical Union (AGU) Fall Meeting, which took place December 15-19, 2014 in San Francisco, California. The AGU Fall Meeting is one of the largest annual scientific meetings in the world with approximately 24,000 attendees this year in more than 1700 sessions. The AGU Fall Meeting’s scientific program spans the Earth and space sciences, engineering as well as climate related research and the social impacts of climate and environmental changes. Team ADNET participated in this year’s AGU conference with staff members spanning the full spectrum of services that our SESDA 3 contract provides our NASA Goddard Space Flight Center customer. Team ADNET members contributed approximately 20 oral and poster presentations to promote NASA science and information technology services. The exhibit hall is also well attended with over 250 exhibitors showcasing their services and products.

Record-Setting Disk-to-Disk Network Data Transfer by HECN work at SC14

December 15, 2014

96+ Gbps HECN transfer graph
SESDA’s High End Computer Networking (HECN) Team worked with the Mid-Atlantic Crossroads (MAX), Energy Sciences Network (ESnet), and StarLight network R&D partners to establish a 100 GigE wide area network (WAN) path between NASA Goddard Space Flight Center in Maryland and the SuperComputing 2014 (SC14) event in New Orleans (for details of SC14 see: The HECN team built the high performance RAID servers that were used to achieve a record of 96+ Gigabits per second (Gbps) disk-to-disk network file data transfer rate, utilizing 8 cores and 8 network streams to transfer 2 Terabytes of data. The accompanying figure shows some of the data transfer results during the demonstrations.
