Architecturally-diverse systems (containing co- processors such as reconfigurable logic and graphics engines) have received significant attention recently in the high perfor- mance computing community. They are new enough, however, that application development tools are quite limited. This paper describes our performance measurement system, TimeTrial, that automates performance measurements of diverse, streaming data applications. TimeTrial enables low-impact measurements by interpreting performance queries in the TimeTrial language and by compiling these queries to highly-specific, optimized instrumentation that aggressively performs lossy compression on the performance meta-data. Currently, TimeTrial supports multi-core processors and reconfigurable logic, with GPU support under development. We present the TimeTrial language and its associated compiler, including its use in optimizing the performance of an example computational science problem.
