The LDM group's work supports the following Unidata funding proposal focus areas:
Broadening participation and expanding community services by providing near real-time atmospheric data for research and education
Advancing data services by providing near real-time atmospheric data for research and education
Developing and deploying useful tools by developing the software and providing it free of charge
Enhancing user support services by providing free expert support for the software
Providing leadership in cyberinfrastructure by being the #1 “advanced application” on Internet-II
Promoting diversity by expanding opportunities by democratizing access to atmospheric data
Installed LDM 6.9.0 on Tom Yoksas' machine (Yakov). So far so, so good.
Dr. Malathi Veeraraghavan, professor of Electrical and Computer Engineering at the University of Virginia, has chosen the LDM as the subject of an NSF EAGER grant on the applicability of using virtual circuits for large-scale data distribution. The grant has been awarded and Steve Emmerson is a co-PI.
An end-to-end skeleton has been created that successfully distributes data using a peer-to-peer-based publish/subscribe system.
We plan to continue the following activities:
Deployment of LDM 6.9.0 on the Unidata Program Center's backend cluster
Release of LDM 6.9.0
Fall LDM training-workshop
Continue development of the next-generation LDM
We plan to organize or take part in the following:
Provide advice to Jie Lie, Dr. Veeraraghavan's graduate student at the University of Virginia, on modifying the LDM to use virtual circuits.
The LDM data-rate on Internet-II is currently about 24 TB/week (or 3.4 TB/day, 140 GB/hr, 2.4 GB/min, 40 MB/s, 320 Mb/s). It has been observed to range up to as high as 34 TB/week during peak summer storm seasons.
