Challenges and Experience in Prototyping a Multi-Modal Stream Analytic and Monitoring Application on System S

In this paper, the authors describe the challenges of prototyping a reference application on System S, a distributed stream processing middleware under development at IBM Research. With a large number of stream PEs (Processing Elements) implementing various stream analytic algorithms, running on a large-scale, distributed cluster of nodes, and collaboratively digesting several multi-modal source streams with vastly differing rates, prototyping a reference application on System S faces many challenges. Specifically, they focus on the experience in prototyping DAC (Disaster Assistance Claim monitoring), a reference application dealing with multi-modal stream analytic and monitoring.
