In the past decade, the world has been dominated by exponential growth of digital information. While the computing hardware (e.g., CPU, storage, and network) has managed to keep the pace, few software systems can effectively and efficiently handle very large, geographically distributed datasets. We are a team that develop open source software to bridge this gap. Our current effort include UDT and Sector/Sphere. UDT is a high speed data transfer protocol. Sector is a high performance distributed wide area storage system with in-storage data processing ability.
