The Data Reservoir Project is designing an online 2-PFLOPS system, part of Japanís GRAPE-DR project, to be operational in 2008. Its goal is to create a global grid infrastructure to enable distributed data sharing and high-speed computing for data analysis and numerical simulations.

Data Reservoir Project

In April 2006, the Project set Internet2 Land Speed Records (I2-LSR) in the IPv6 single and multi-stream categories. For the IPv6 records, the Project created a network path over 30,000 kilometers in distance crossing eight international networks and exchange points. The team successfully transferred data at a rate of 8.80Gbps, which is equal to 264,147 terabit-meters per second (Tb-m/s). For the IPv6 record, the team created a path over 30,000 kilometers in distance crossing five international networks, transferring data at a rate of 6.96Gbps, achieving a mark of 208,800 terabit-meters per second (Tb-m/s).

"Data Reservoir on very-long-distance IPv6/IPv4 network" received the SC|05 Bandwidth Challenge award for "Fastest IPv6". They achieved 6.84Gbps peak traffic on IPv6.

On 14 November 2005, this group won the Internet2 Land Speed Records (I2-LSR) in both the IPv6 single-stream and IPv6 multi-stream categories for successfully transferring data at a rate of 5.58Gbps over a distance of over 30,000 kilometers traversing the WIDE, IEEAF, JGN2
