USENIX Association 11th USENIX Conference on File and Storage Technologies (FAST ’13) 215 Getting Real: Lessons in Transitioning Research Simulations into Hardware Systems

by Mohit Saxena, Yiying Zhang, Michael M. Swift, Andrea C. Arpaci-dusseau, Remzi H. Arpaci-dusseau
"... Flash-based solid-state drives have revolutionized stor-age with their high performance. Their sophisticated in-ternal mechanisms have led to a plethora of research on how to optimize applications, file systems, and internal SSD designs. Due to the closed nature of commercial de-vices though, most r ..."

-expected complexities in implementing extensions to the storage interface. We describe our implementation process and extract a set of lessons applicable to other SSD prototypes. With our prototype we validate the performance claims of FlashTier and show a 45-52 % performance improvement over caching with an SSD and a

In the absence of the branched amino acid biosynthetic pathway in animals, metabolically stable a-IPM presents an EC 50 equal to 0.8837 mM and fast ‘‘OFF-ON’ ’ kinetics (t 50ON = 43 min, t 50OFF = 2.18 h), it enters the cells via passive

Opaque control-flow integrity.

"... Abstract-A new binary software randomization and ControlFlow Integrity (CFI) enforcement system is presented, which is the first to efficiently resist code-reuse attacks launched by informed adversaries who possess full knowledge of the inmemory code layout of victim programs. The defense mitigates ..."

. Moreover, O-CFI's control-flow checking logic is implemented using Intel x86/x64 memory-protection extensions (MPX) that are expected to be hardware-accelerated in commodity CPUs from 2015 onwards. We therefore expect even better performance for O-CFI in the near future. Our contributions

RICE UNIVERSITY Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing

The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demon-strated that structured signals can be acquired with just a small number of linear measurements, on the order of the signal complexity. In practice, this enables lower sampling rates that can be more easily achieved by current hardware designs. The primary bottleneck that limits ADC sam-pling rates is quantization, i.e., higher bit-depths impose lower sampling rates. Thus, the decreased sampling rates of CS ADCs accommodate the otherwise limiting quantizer of conventional ADCs. In this thesis, we consider a different approach to CS ADC by shifting towards lower quantizer bit-depths rather than lower sampling rates. We explore the extreme case where each measurement is quantized to just one bit, representing its sign. We develop a new theoretical framework to analyze this extreme case and develop new algorithms for signal reconstruction from such coarsely quantized measurements. The 1-bit CS framework leads us to scenarios where it may be more appropriate to reduce bit-depth instead of sampling rate. We find that there exist two distinct regimes of operation that correspond to high/low signal-to-noise ratio (SNR). In the measurement

Abstract. Strangeness flavor yield s and the entropy yield S are the observables of the deconfined quark-gluon state of matter which can be studied in the entire available experimental energy range at AGS, SPS, RHIC, and, in near future, at the LHC energy range. We present here a comprehensive analysis of strange, soft hadron production as function of energy and reaction volume. We discuss the physical properties of the final state and argue how evidence about the primordial QGP emerges. 1.
