An Integrated Global Service for File Transfer and Management in a Network (FTM)

informational resources has emerged as an important requirement for scientific simulations using high-performance computing facilities. Both the input data and the output generated have reached levels exceeding the data management capabilities and the storage capacities of the researcher's workstation or other local facilities. We here describe FTM, a system deployed at the University of Stuttgart for the uniform, secure, interactive Access, Transfer, and Management of informational resources in a network or Grid consisting of facilities at distributed Virtual Organizations. The extension of this system to support computational workflows is also reported Keywords—file transfer, Grid environments.
