ABSTRACT
Abstract:
Developing a capacity to test distributed systems hinges on being able to generate, in real-time, the workloads that these systems are to process. Currently, the majority of prior work in this area has focused on the re-production of workload traces at the network-level, e.g., Harpoon, ns-2, OpNet, tcpreplay, etc., whereas for many distributed systems reproducing application level workload characteristics can be more informative from the testing perspective. This seminar details the development of an MPI-based application level workload generation tool that scales to using multiple machines to re-create complex multi-homed workloads. The tool supports the standard abilities to produce both statistically described workloads as well as re-instantiating previously captured workload traces. Unlike prior tools, the contents of the payloads themselves can be varied as part of the workload generation process in a manner that allows the production of both stateless and stateful application level workloads.
