Improving the Efficiency of Parallel Applications on Multithreaded and Multicore Systems
… a runtime system that uses live analysis of hardware event rates through the prediction model to optimize applications dynamically. We discuss a dynamic, phase-aware performance prediction model (DPAPP), which combines statistical learning techniques, including multivariate linear regression …

Structure-based Optimizations for Sparse Matrix-Vector Multiply
… method. We validate performance results using hardware event counters, which demonstrate significantly improved cache and pipeline utilization. Pattern-based Representation (PBR) exploits recurring block nonzero patterns by generating custom code for each recurring block pattern. In this way, …

Automated performance characterization of applications using hardware monitoring events
… of the complexity of the state of the art hardware technologies. Most modern processors incorporate multiple cores that have superscalar, out-of-order, and speculative pipelines. They also have multiple functional units and deeper buffers for sustaining high levels of instruction level …

Selective Dynamic Analysis of Virtualized Whole-System Guest Environments
… environment.</p> <p>DECAF provides a novel, hardware event-based method of just-in-time virtual machine introspection (VMI) to address the semantic gap problem. It also implements a novel instruction-level taint tracking engine at bitwise level of granularity, ensuring that taint propagation …
