Low-Impact Monitoring of Streaming Systems

The centerpiece of the activities to date on this project is the design, development, and implementation of the TimeTrial performance monitor. TimeTrial is a tool that enables observation of critical performance properties of streaming data applications without significantly perturbing the execution of the application under observation. It supports applications deployed on architecturally diverse computer systems, initially including the combination of multicore processors and/or field-programmable gate arrays (FPGAs).
