As file systems reach the petabytes scale, users and administrators are increasingly interested in acquiring high-level analytical information for file management and analysis. Two particularly important tasks are the processing of aggregate and top-k queries which, unfortunately , cannot be quickly answered by hierarchical file systems such as ext3 and(More)
Power, energy, and compute time are all important metrics that can act as either objectives or constraints in program or system optimization. Recent microprocessors include sensors (counters) for monitoring these metrics as well as on-chip system controllers that may use this information. Code optimization is relatively straightforward if the measurements(More)
Computational modeling of cardiac electrophysiology is a powerful tool for studying arrhythmia mechanisms. In particular, cardiac models are useful for gaining insights into experimental studies, and in the foreseeable future they will be used by clinicians to improve therapy for the patients suffering from complex arrhythmias. Such models are highly(More)
Recent developments in modern computational accelerators like Graphics Processing Units (GPUs) and coprocessors provide great opportunities for making scientific applications run faster than ever before. However, efficient parallelization of scientific code using new programming tools like CUDA requires a high level of expertise that is not available to(More)
