This work performs a thorough characterization and analysis of the open source Lucene search library. The article describes in detail the architecture, functionality, and micro-architectural behavior of the search engine, ...

This chapter evaluates and defines a methodology for the oracle selection of the monitors and knobs to use to configure an HPC system running a scientific application while satisfying the application’s requirements and not ...

This work presents GeST (Generator for Stress-Tests): a framework for automatically generating CPU stress-tests. The framework is based on genetic algorithm search and can be used to maximize different target CPU metrics ...

The goal of the HARPA solution is to overcome the performance variability (PV) by enabling next-generation embedded and high-performance platforms using heterogeneous many-core processors to provide cost-effectively ...

Worst-case dI/dt voltage noise is typically characterized post-silicon using direct voltage measurements through either on-package measurement points or on-chip dedicated circuitry. These approaches consume expensive pad ...

This work proposes sensing CPU voltage noise through wireless electromagnetic (EM) emanations from the CPU. Compared to previous voltage monitoring methodologies, this approach is not intrusive as it does not require direct ...

The common practice for quantifying the benefit(s) of design-time architectural choices of server processors is often limited to the chip- or server-level. This quantification process invariably entails the use of salient ...
