PHP is the dominant server-side scripting language used to implement dynamic web content. Just-in-time compilation, as implemented in Facebook's state-of-the-art HipHopVM, helps mitigate the poor performance of PHP, but substantial overheads remain, especially for realistic, large-scale PHP applications. This paper analyzes such applications and shows that there is little opportunity for conventional...
Scripting languages like Javascript and PHP are widely used to implement application logic for dynamically-generated web pages. Their popularity is due in large part to their flexible syntax and dynamic type system, which enable rapid turnaround time for prototyping, releasing, and updating web site features and capabilities. The most common complex data structure in these languages is the hash map,...
Prior research in neutrally-inspired perceptron predictors and Geometric History Length-based TAGE predictors has shown significant improvements in branch prediction accuracy by exploiting correlations in long branch histories. However, not all branches in the long branch history provide useful context. Biased branches resolve as either taken or not-taken virtually every time. Including them in the...
Sequential consistency is arguably the most intuitive memory consistency model for shared-memory multi-threaded programming, yet it appears to be a poor fit for simple, in-order processors that are most attractive in the power-constrained many-core era. This paper proposes an intuitively appealing and straightforward framework for ensuring sequentially consistent execution. Prior schemes have enabled...
In this paper, we present a timing-driven test generator to sensitize multiple aligned aggressors coupled to a delay-sensitive victim path to detect the combination of a delay spot defect and crosstalk-induced slowdown. The framework uses parasitic capacitance information, timing windows and crosstalk-induced delay estimates to screen out unaligned or ineffective aggressors coupled to a victim path,...
