Disconnected operation in scientific workflow management systems

Scientific workflows tend to be time consuming and data intensive, and today’s fast paced mobile culture does not afford researchers the luxury of neither sitting at a computer for days at a time, waiting for experiments. While business workflow research has addressed this issue, the solutions developed are not applicable to scientifc workflow systems, as the infrastructure of the two are not trivially interchangeable. we will explore four possible alternatives to the problem of disconnected operation in scientific workflow environmentsdecentralized, proxy, distributed, and hybrid approaches.
